Education is the process of acquiring knowledge, skills, values, and attitudes through formal or informal instruction. It is a fundamental aspect of human development that empowers individuals with the tools they need to participate effectively in society and pursue personal and professional goals. It is vital for personal growth, social progress, economic development, and the overall well-being of individuals and communities.
Key aspects of education include:
Formal: Formal refers to structured and organized learning that takes place in educational institutions such as schools, colleges, and universities. It follows a predefined curriculum and is delivered by trained teachers or instructors.
Informal: Informal occurs outside of formal institutions and includes learning through daily experiences, interactions with others, and self-directed exploration. They can be equally valuable in acquiring practical skills and life knowledge.
Primary: Primary is the initial phase of formal education and typically covers early childhood through elementary school. It lays the foundation for literacy, numeracy, and critical thinking.
Secondary: Secondary follows primary education and includes middle and high school. It provides a more comprehensive curriculum and prepares students for higher education or vocational paths.
Higher: Higher encompasses post-secondary learning in colleges and universities. It offers specialized knowledge and skills through degree programs in various fields, such as arts, sciences, engineering, medicine, business, and more.
Vocational: Vocational provides training and skills development for specific trades or professions, preparing individuals for careers in fields like plumbing, carpentry, healthcare, and technology.
Continuing: Continuing allows individuals to enhance their knowledge and skills beyond formal education. It includes workshops, seminars, online courses, and professional development programs.
Access and Inclusivity: Ensuring equal access to education for all individuals, regardless of socioeconomic background, gender, ethnicity, or physical abilities, is essential for promoting social equity.
Education is a transformative process that empowers individuals to think critically, solve problems, communicate effectively, and adapt to changing circumstances. It promotes creativity, cultural understanding, and empathy, fostering a more informed and tolerant society. By investing in education, societies can cultivate a skilled and knowledgeable workforce, encourage innovation, and address societal challenges effectively.

In every episode he was in a different profession and he needed to remedy a case. And he did it by investigating the occupation. It could be the military, Hollywood, whatever. And every time he had to very quickly perceive the implicit data in the field.
We have already seen how corporations are the instruments and strategies of information science to improve how we diagnose most cancers, battle global warming and extra.
Data science, for my part, is the way forward for this type of work. It is the only method to do it effectively, replicably, and get great results.
Yet, very few folks actually become knowledge scientists. It’s a combination of exhausting skills (like studying Python and SQL) and delicate expertise (like business skills or communication expertise) and extra. I believe that knowledge science has the facility to enhance the human condition by serving to us examine phenomena, acquire new information and integrate previous knowledge with new ideas. Through the gathering, analysis and interpretation of information, knowledge scientists help improve how humans make decisions and how algorithms optimize outcomes.
It’s an exciting time to be alive, as a result of there’s extra data obtainable than ever before. There is more information than we could ever analyze, a lot much less perceive. In that context, data science is our technique of taming unstructured information and gathering insight. I’m a cultural sociologist and learning data science is essential to me as a result of folks add Content tons of textual content that may inform us about their worldviews and their values, if solely we know tips on how to analyze it. Do you know the present , the old present from the 80s?
Data Scientists and Machine Learning Engineers are in great demand and on the forefront of coming AI revolution, from making new life-saving medicines to self-driving cars to annoyingly personalized adverts. This is one thing that I’ve already talked about within the intro.
Well, a part of the issue is that many aspiring information scientists don’t know what to expect from this subject. Or even worse, based on the numerous Best Data Science Courses in Bangalore misleading (typically scammy) “how to turn into a knowledge scientist” articles, they have false expectations.
And once they hit the wall, they get demotivated and give up. One is the truth that information science is a rapidly evolving area, in order that a large part of a data scientist’s work, a minimum of as I envision it, I actually like that my work is evolving with the progress of information science, in order that I by no means get bored. For me, information science was a approach to become a detective. And because I am very curious about very totally different strategies in science, for me, it is precisely what I wished.
You have much more tools and much more flexibility in the way in which you possibly can collect knowledge, the way in which you possibly can exploit a number of databases all of sudden, and produce something really usable as nicely. Data science is the long run, and it’s better to be on the slicing-edge than left behind. Don’t get me mistaken, I nonetheless assume that right now, you should learn these things as a result of they are half of the present data science and analytics ecosystem and also part of the training curve itself.
He needed to discuss to people, perceive how they thought, stuff like that. And I really feel a bit like that with information science. When you’re knowledge scientist, you spend plenty of time, or no less than I do, talking with specialists of the sector and very often they have plenty of implicit data. Did you flirt with the thought of studying data science? This has been a really scorching subject in the previous couple of years and will probably be one within the upcoming few, for certain.
I’ve been working towards data science for 6+ years now. I’ve held senior DS positions (in addition to teaching). But I wouldn’t say that I mastered information science or analytics.
Many individuals need to be taught information science… yet, not too a lot of them turn into knowledge scientists after all. Data science is the way forward for utilized econometrics, I would positively say…[At my final job], we did a lot of public analysis nevertheless it was not formal.
I know for a proven fact that no one can grasp information science in 1 month. In fact, my private estimation (based on students I labored with) is that from zero to the junior degree the learning process Data Science Training Institute in Bangalore will take ~6-9 months. In this text, I want to show you 4 untold truths that you need to know about learning information science – and I have never seen them written down anyplace else earlier than.

Different branches of psychology: First realize, what’s Psychology? People use the term psychological, mental or psychic or psycho, etc., very freely. But many of these who use these terms are far away from having a true understanding of nature, scope, methods, and uses of psychology as a science. Today, psychology finds useful applications in an individual’s life almost from the womb to the tomb; psychology essay writing topics.
Here are Explain the various Categories or Branches of Psychology.
The commoner is extremely much conscious of the uses of other sciences, like physics, chemistry, biology, medicine and, statistics, in lifestyle but finds it difficult to understand the possible uses of psychology in lifestyle. Various regions of specialization in psychology have emerged over the years; a number of these discussions during this section.
The following the various branches of Psychology below are;
Cognitive Psychology:
It investigates mental processes involved within the acquisition, storage, manipulation, and transformation of data received from the environment alongside its use and communication. the main cognitive processes are attention, perception, memory, reasoning, problem-solving, decision-making, and language. you’ll be studying these topics later during this textbook.
To study these cognitive procedures, psychologists conduct the exercise in laboratory settings; a number of them also follow an ecological approach, i.e. an approach which focuses on the environmental factors, to review cognitive processes during a natural setting. Cognitive psychologists often Co-operation with neuroscientists and computer scientists.
Biological Psychology:
Focus on the connection between behavior and therefore the physical system, including the brain and therefore the remainder of the systema nervosum, the system, and genetics. Biological psychologists often Co-operation with neuroscientists, zoologists, and anthropologists. Neuropsychology has emerged as a region of investigation where psychologists and neuroscientists are working together.
Researchers are studying the role of neurotransmitters or chemical substances that are liable for neural communication in several areas of the brain and thus in associated mental functions. they are doing their research on people with the traditional functioning brain also as on people with the damaged brain by following advanced technologies like EEG, PET, and fMRI, etc. about which you’ll study later.
Developmental Psychology:
It studies the physical, social, and psychological changes that occur at different ages and stages over a life-span, from conception to adulthood. the first concern of developmental psychologists is how we become what we are. for several years the main emphasis was on child and adolescent development. However today an increasing number of developmental psychologists show a robust interest in adult development and aging.
They specialize in the biological, socio-cultural, and environmental factors that affect psychological symptoms like intelligence, cognition, emotion, temperament, morality, and social relationship. Human life passes through various stages of development from conception to adulthood.
This branch explains the expansion and development of varied processes about behavior. Developmental psychologists collaborate with anthropologists, educationists, neurologists, social workers, counselors, and almost every branch of data where there’s a priority for the expansion and development of a person’s being.
Social Psychology:
They Explore how people are suffering from their social environments, how people believe, and influence others. Social psychologists have an interest in such topics as attitudes, homology, and obedience to authority, interpersonal attraction, subsidiary behavior or conduct, prejudice, aggression, social motivation, inter-group relations, and so on; a person’s being maybe a social animal.
Naturally, the behavior of a private is influenced by society, and successively influences society. psychology essay writing topics affect the interrelationships of individuals among themselves likes and dislikes of individuals, attitudes and interests, the prejudices and social distances people have, group behavior, group cohesiveness, group conflicts, etc.
Cross-cultural and Cultural Psychology:
They examine the role of culture in understanding behavior, thought, and emotion. It assumes that human behavior isn’t only a mirrored image of human-biological potential but also a product of culture. Therefore behavior should be studied in its socio-cultural reference. As you’ll be studying in several chapters of this book; culture influences human behavior in some ways and ranging degrees.
Environmental Psychology:
They study the interaction of physical factors like temperature, humidity, pollution, and natural disasters on human behavior. The influence of the physical arrangement of the workplace on health, spirit, and interpersonal relations also are investigated. Current topics of research during this field are the extent to which, disposal of waste, population explosion, conservation of energy, efficient use of community resources are related to, and are functions of human behavior.
Health Psychology:
They specialize in the role of psychological factors (for example, stress, anxiety) within the development, prevention, and treatment of illness. Areas of interest for a health psychologist are stress and coping, the connection between psychological factors and health, patient-doctor relationships, and ways of promoting health-enhancing factors.
Clinical and Counselling Psychology:
Deals with causes, treatment, and prevention of various sorts of psychological disorders like anxiety, depression, eating disorders, and chronic drug abuse. A related area is counseling, which aims to enhance everyday functioning by helping people solve problems in daily living and cope more effectively with challenging situations. This branch deals with the therapeutic aspects of psycho or mental disorders.
There are many sorts of mental diseases requiring varied sorts of therapies like chemotherapy, psychotherapy, recreational and occupational therapies, behavior modification, etc. The work of clinical psychologists doesn’t differ from that of counseling psychologists although a counseling psychologist sometimes deals with people that have less serious problems.
In many illustrations, counseling psychologist works with students, recommending them about personal problems and career planning. Like clinical psychologists, psychiatrists also study the reason, treatment, and prevention of psychological disorders.
How are psychotherapist s and psychiatrists different? A clinical psychologist features a degree in psychology, which incorporates intensive training in treating people with psychological disorders. In contrast, a psychiatrist features a medical degree with years of specialized training within the treatment of psychological disorders. One important difference is that psychiatrists can prescribe medications; and, give electroshock treatments whereas clinical psychologists cannot.
Industrial or Organizational Psychology:
Deals with workplace behavior, that specialize in both the workers and therefore the organizations that employ them. Industrial or organizational psychologists are concerned with training employees, improving work conditions, and developing criteria for choosing employees. citizenry are different from machines.
They will have huge problems in their workplace like adjustment, safety, security, health, financial, and such other problems and solutions. Both the management and workers got to cooperate in handling such problems. applied psychology seeks the appliance of psychological principles, theories, and techniques for the study of these problems and therefore the industrial environment.
For example, an organizational psychologist might recommend that a corporation may adopt a replacement management structure that might increase communication between managers and staff. The background of commercial and organizational psychologists often includes training in cognitive and psychology.
Educational Psychology:
It is Studies how people of all ages learn. Educational psychologists primarily help develop instructional methods and materials wont to train people in both educational and work settings. they’re also concerned with research on problems with relevance for education, counseling, and learning problems.
This is the foremost important field where psychological principles are applied. within the field of education “learner” is that the focus. Another side like management, teachers, teaching, and learning aids are all meant for learners. Learners differ in their abilities, hence they have different approaches to teaching, learning material, etc.
This branch addresses the issues and enhancements in teaching and learning processes. A related field, school psychology, focuses on designing programs that promote the intellectual, social, and emotional development of youngsters, including those with special needs. they struggle to use knowledge of psychology essay writing topics during a school setting.
Sports Psychology:
Applies psychological principles to enhance sports performance by enhancing their motivation. Sports psychology may be a relatively new field but is gaining acceptance worldwide.

Other Emerging Branches of Psychology:
The interdisciplinary specializes in research and application of psychology essay writing topics has led to the emergence of various areas like aviation psychology, space psychology, military psychology, forensic psychology, rural psychology, engineering psychology, managerial psychology, community psychology, the psychology of girls, and political psychology, to call a couple of.
Learn about the different types of environmental pollution and their impact on the natural environment. Find out how pollution can cause adverse changes and harm ecosystems.
What is Pollution and Types of Environmental Pollution?
Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point-source or nonpoint-source pollution.
The meaning of Pollution:“The presence in or introduction into the environment of a substance which has harmful or poisonous effects.”
History of Pollution:
Air pollution has always accompanied civilizations. Pollution started in prehistoric times when man created the first fires. According to a 1983 article in the journal Science, “soot” found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires.” Metal forging appears to be a key turning point in creating significant air pollution levels outside the home. Core samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman, and Chinese metal production. Still, at that time the pollution was comparatively small and could be handled by nature.
What is Environmental Pollution?
Pollution, also called environmental pollution, is the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution are (classified by environment) air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and even plastic pollution.
Although environmental pollution can cause by natural events such as forest fires and active volcanoes. The use of the word pollution generally implies that the contaminants have an anthropogenic source—that is, a source created by human activities. Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place. Indeed, ancient human settlements frequently recognized by their pollutants—shell mounds and rubble heaps. Pollution was not a serious problem as long as there was enough space available for each individual or group. However, with the establishment of permanent settlements by great numbers of people, pollution became a problem, and it has remained one ever since.
Cities of ancient times were often noxious places, fouled by human wastes and debris. Beginning about 1000ce, the use of coal for fuel caused considerable air pollution, and the conversion of coal to coke for iron smelting beginning in the 17th century exacerbated the problem. In Europe, from the Middle Ages well into the early modern era. Unsanitary urban conditions favored the outbreak of population-decimating epidemics of disease, from plague to cholera and typhoid fever. Through the 19th century, water and air pollution and the accumulation of solid wastes were largely problems of congested urban areas. But, with the rapid spread of industrialization and the growth of the human population to unprecedented levels, pollution became a universal problem.
By the middle of the 20th century, an awareness of the need to protect air, water, and land environments from pollution had developed among the general public. In particular, the publication in 1962 of Rachel Carson’s book Silent Spring focused attention on the environmental damage caused by improper use of pesticides. Such as DDT and other persistent chemicals that accumulate in the food chain and disrupt the natural balance of ecosystems on a wide scale.
The presence of environmental pollution raises the issue of pollution control. Great efforts made to limit the release of harmful substances into the environment. Through air pollution control, wastewater treatment, solid-waste management, hazardous waste management, and recycling.
Types of Environmental Pollution
The major types of environmental pollution listed below along with the particular contaminant relevant to each of them:
Air pollution: the release of chemicals and particulates into the atmosphere. Common gaseous pollutants include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smog create as nitrogen oxides and hydrocarbons react to sunlight. Particulate matter or fine dust characterize by its micrometer size from PM10 to PM2.5.
Light pollution: includes light trespass, over-illumination, and astronomical interference.
Littering: the criminal throwing of inappropriate synthetic objects, unremoved, onto public and private properties.
Noise pollution: which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.
Soil contamination occurs when chemicals released by spill or underground leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides, and chlorinated hydrocarbons.
Radioactive contamination, results from 20th-century activities in atomic physics. Such as nuclear power generation and nuclear weapons research, manufacture, and deployment. (See alpha emitters and actinides in the environment.)
Visual pollution, can refer to the presence of overhead power lines, motorway billboards, scarred landforms (as from strip mining), open storage of trash, municipal solid waste, or space debris.
Water pollution, by the discharge of wastewater from commercial and industrial waste (intentionally or through spills) into surface waters. Discharges of untreated domestic sewage, and chemical contaminants, such as chlorine, from treated sewage. Release of waste and contaminants into surface runoff flowing to surface waters (including urban runoff and agricultural runoff, which may contain chemical fertilizers and pesticides). Waste disposal and leaching into groundwater; eutrophication and littering.
The characteristics of the Troposphere: The atmosphere has a multi-layered structure consisting of the following basic layers. Troposphere, Stratosphere, Mesosphere, Ionosphere, and Exosphere. The word troposphere derives from the Greek word Tropo and it means turbulence or mixing. This is the lowermost layer of the atmosphere and is known as the troposphere and is the most important lowest layer of earth surface because almost all the weather events ( e.g fog, cloud, due, frost, hailstorm, storms, cloud-thunder, lightning, etc.) occur in this lowest layer. Thus the troposphere is of the utmost significance for all life forms including man because these are concentrated in the lowermost portion of the atmosphere.
Here explains; What are the Characteristics of the Troposphere? Read and learn.
Temperature decreases with increasing height at the average rate of 6.50 C per 1000m (1 kilometer) Which is called a normal lapse rate. The height of the troposphere changes from the equator towards the poles (decreases) and from one season of a year to the other season(increases during summer while decreases during winter). The average height of the troposphere is about 16km over the equator and 6km over the poles. The upper limits of the troposphere are called TROPOPAUSE.
What is the Importance of the Troposphere?
The troposphere provides several important benefits: it holds nearly all of the water vapor in the Earth’s atmosphere, regulates temperature, and produces weather. The troposphere forms the lowest level of the Earth’s atmosphere, extending down to the surface of the Earth. This lowest layer also features the heaviest weight of all earth surface atmosphere layers, comprising approximately 75 percent of the total atmospheric weight.
The troposphere varies in thickness and height around the world. At its highest point, the troposphere extends 12 miles into the air. At its lowest point, this layer reaches 4 miles above sea level. Regardless of height, the troposphere facilitates temperature regulation and cloud formation. It contains the highest temperatures closer to its base; these warm temperatures help the troposphere retain water vapor, which releases in the form of precipitation.
The troposphere also serves as the starting point for the Earth’s water cycle. This process begins when the sun pulls water into the atmosphere through evaporation. Water then cools and condenses, forming clouds. Clouds store water particles, which are released in the form of rain, sleet, or snow depending on the time of year and region. The troposphere also traps gases, such as carbon dioxide and nitrogen. Excess accumulation of these substances creates environmental problems, such as smog and air pollution.
Characteristics of the Troposphere:
The following Characteristics below are:
Most of the weather phenomena take place in this lowest layer. The troposphere contains almost all the water vapor and most of the dust.
This layer subject to intense mixing due to both horizontal and vertical mixing.
Temperature decreases with height at an average rate of 10C per 167m of height above sea level. This calls the normal lapse rate.
The troposphere extends up to a height of about 18km at the equator and declines gradually to a height of 8km at the poles.
The upper limit of the troposphere calls the tropopause. The temperature stops decreasing in it. It may be as low as -580C.
All-weather changes occur in the troposphere. Since it contains most of the water vapor, clouds form in this layer of earth surface.
Frequently Asked Questions (FAQs)
What is the troposphere?
The troposphere is the lowest layer of earth’s surface atmosphere, where almost all weather events occur, including clouds, rain, and storms. It extends from the Earth’s surface to an average height of about 16 km over the equator and about 6 km over the poles.
Why is the troposphere important?
The troposphere is vital for life on earth surface as it holds nearly all the water vapor in the atmosphere, regulates temperature, and is the primary site for weather formation. It also plays a crucial role in the water cycle.
How does temperature change in the troposphere?
In the troposphere, temperature decreases with increasing height at an average rate of 6.5°C for every 1000 meters (1 kilometer) of elevation. This phenomenon is known as the normal lapse rate.
What is the upper limit of the troposphere called?
The upper boundary of the troposphere is known as the tropopause. At this boundary, the temperature stops decreasing, and it may reach temperatures as low as -58°C.
What gases are found in the troposphere?
The troposphere contains essential gases such as nitrogen and carbon dioxide. However, an excess accumulation of these gases can lead to environmental issues, including smog and air pollution.
How thick is the troposphere?
The troposphere varies in thickness globally; it can reach up to 18 km at the equator and as low as 8 km at the poles.
What is the Troposphere? It is the lowest portion of Earth’s atmosphere and is also where nearly all weather takes place. It contains approximately 75% of the atmosphere’s mass and 99% of the total mass of water vapor and aerosols. The average depths of the troposphere are 20 km (12 mi) in the tropics, 17 km (11 mi) in the mid-latitudes, and 7 km (4.3 mi) in the polar regions in winter. The lowest part of them, where friction with the Earth’s surface influences airflow, is the planetary boundary layer. Also, This layer is typically a few hundred meters to 2 km (1.2 mi) deep depending on the landform and time of day.
Here read and learn; What is the Troposphere? Meaning and Definition.
Atop the troposphere is the tropopause, which is the border between the troposphere and stratosphere. The tropopause is an inversion layer, where the air temperature ceases to decrease with height and remains constant through its thickness.
The word troposphere derives from the Greek: Tropos for “turn, turn toward, trope” and “-sphere” (as in, the Earth), reflecting the fact that rotational turbulent mixing plays an important role in the troposphere’s structure and behavior. As well as Most of the phenomena associated with day-to-day weather occur in them.
The Troposphere:
It is the lowest major atmospheric layer, extending from the Earth’s surface up to the bottom of the stratosphere. Also, It is where all of Earth’s weather occurs. It contains approximately 80% of the total mass of the atmosphere.
It characterizes by decreasing temperature with height (at an average rate of 3.5 degrees F per thousand feet, or 6.5 degrees C per kilometer). In contrast, the stratosphere has either constant or slowly increasing temperatures with height.
The boundary between the troposphere and the stratosphere is called the “tropopause”, located at an altitude of around 5 miles in the winter, to around 8 miles high in the summer, and as high as 11 or 12 miles in the deep tropics.
When you see the top of a thunderstorm flatten out into an anvil cloud. It is usually because the updrafts in the storm have reached the tropopause. Where the environmental air is warmer than the cloudy air in the storm, and so the cloudy air stops rising.
Definition of The Troposphere:
The lowest densest part of the earth’s atmosphere in which most weather changes occur and temperature generally decreases rapidly with altitude and which extends from the earth’s surface to the bottom of the stratosphere at about 7 miles (11 kilometers) high.
Overview of The Troposphere:
It is the lowest layer of Earth’s atmosphere. Most of the mass (about 75-80%) of the atmosphere is in them. Most types of clouds are found there, and almost all weather occurs within this layer.
The bottom of them is at Earth’s surface. Also, They extend upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of them varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer). Also, It can be as high as 20 km (12 miles or 65,000 feet) near the equator, and as low as 7 km (4 miles or 23,000 feet) over the poles in winter.
Air is warmest at the bottom of the troposphere near the ground level. Also, Air gets colder as one rises through them. That’s why the peaks of tall mountains can be snow-covered even in the summertime.
Air pressure and the density of the air also decrease with altitude. That’s why the cabins of high-flying jet aircraft pressurize.
The layer immediately above them calls the stratosphere. Also, The boundary between the troposphere and the stratosphere calls the “tropopause“.
Frequently Asked Questions
What is the Troposphere?
The troposphere is the lowest portion of Earth’s atmosphere, extending from the Earth’s surface up to the bottom of the stratosphere. It is where nearly all weather occurs and contains about 75-80% of the atmosphere’s mass.
How deep is the Troposphere?
The average depth of the troposphere varies by location: it is about 20 km (12 mi) in the tropics, 17 km (11 mi) in the mid-latitudes, and 7 km (4.3 mi) in the polar regions during winter.
What is the Tropopause?
The tropopause is the boundary layer between the troposphere and the stratosphere. It is characterized by a temperature inversion, meaning the air temperature remains constant or increases with altitude.
Why does temperature decrease in the Troposphere?
Temperature in the troposphere generally decreases with altitude at an average rate of 3.5 degrees F per thousand feet (6.5 degrees C per kilometer) due to the thermal structure and the influence of the Earth’s surface heating.
What types of weather phenomena occur in the Troposphere?
Most types of weather phenomena, including clouds, rain, thunderstorms, and wind patterns, occur within the troposphere.
How does altitude affect air pressure in the Troposphere?
Air pressure and density decrease with altitude in the troposphere. This change is significant, which is why high-flying jets must pressurize their cabins to ensure passenger comfort and safety.
Where is the warmest air located in the Troposphere?
The air is warmest at the bottom of the troposphere, near ground level. As altitude increases, the temperature decreases, leading to colder air at higher elevations.
How does the height of the Troposphere change?
The height of the troposphere varies depending on latitude and season. It is generally higher in tropical regions (up to 20 km) and lower over polar regions (as low as 7 km in winter).
What happens to updrafts in a thunderstorm as they reach the Tropopause?
When the updrafts in a thunderstorm reach the tropopause, they encounter warmer environmental air, which stops the cloudy air from rising further, often causing the characteristic anvil shape of thunderstorm clouds.
What do a human, a rose, and a bacterium have in common? Each of these things along with every other organism on Earth contains the molecular instructions for life, called deoxyribonucleic acid or DNA. Encoded within this DNA (Deoxyribonucleic Acid) are the directions for traits as diverse as the color of a person’s eyes, the scent of a rose, and the way in which bacteria infect a lung cell.
DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus. Organisms composed of cells that contain nuclei are classified as eukaryotes, whereas organisms composed of cells that lack nuclei are classified as prokaryotes. In eukaryotes, DNA is housed within the nucleus, but in prokaryotes, DNA is located directly within the cellular cytoplasm, as there is no nucleus available.
But what, exactly, is DNA? In short, DNA is a complex molecule that consists of many components, a portion of which are passed from parent organisms to their offspring during the process of reproduction. Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals. In turn, this pattern of arrangement ultimately determines each organism’s unique characteristics, thanks to another set of molecules that “read” the pattern and stimulate the chemical and physical processes it calls for.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA’s instructions, or genetic code. Similar to the way the order of letters in the alphabet can be used to form a word, the order of nitrogen bases in a DNA sequence forms genes, which in the language of the cell, tells cells how to make proteins. Another type of nucleic acid, ribonucleic acid, or RNA, translates genetic information from DNA into proteins.
The entire human genome contains about 3 billion bases and about 20,000 genes. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs. The bases on one strand pair with the bases on another strand: adenine pairs with thymine, and guanine pairs with cytosine.
DNA molecules are long so long, in fact, that they can’t fit into cells without the right packaging. To fit inside cells, DNA is coiled tightly to form structures we call chromosomes. Each chromosome contains a single DNA molecule. Humans have 23 pairs of chromosomes, which are found inside the cell’s nucleus.
Why does a DNA molecule consist of two strands? The primary function of DNA is to store and transmit genetic information. To accomplish this function DNA must have two properties. It must be chemically stable so as to reduce the possibility of damage. DNA must also be capable of copying the information it contains. The two-stranded structure of DNA gives it both of these properties. The nucleotide sequence contains the information found in DNA. The nucleotides connect the two strands through hydrogen bonds. Because each nucleotide has a unique complementary nucleotide, each strand contains all the information required to synthesize a new DNA molecule. The double-stranded structure also makes the molecule more stable.
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins.
DNA is well-suited to perform this biological function because of its molecular structure, and because of the development of a series of high-performance enzymes that are fine-tuned to interact with this molecular structure in specific ways. The match between DNA structure and the activities of these enzymes is so effective and well-refined that DNA has become, over evolutionary time, the universal information-storage molecule for all forms of life. Nature has yet to find a better solution than DNA for storing, expressing, and passing along instructions for making proteins.
Alternative DNA structures
DNA Structure A-DNA B-DNA and Z-DNA
DNA (Deoxyribonucleic Acid) exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although, only B-DNA and Z-DNA have been directly observed in functional organisms. The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and concentration of metal ions, and the presence of polyamines in solution.
The first published reports of A-DNA X-ray diffraction patterns—and also B-DNA—used analyses based on Patterson transforms that provided only a limited amount of structural information for oriented fibers of DNA. An alternative analysis was then proposed by Wilkins et al., in 1953, for the in vivo B-DNA X-ray diffraction scattering patterns of highly hydrated DNA fibers in terms of squares of Bessel functions. In the same journal, James Watson and Francis Crick presented their molecular modeling analysis of the DNA X-ray diffraction patterns to suggest that the structure was a double-helix.
Although the B-DNA form is most common under the conditions found in cells, it is not a well-defined conformation but a family of related DNA conformations that occur at the high hydration levels present in living cells. Their corresponding X-ray diffraction and scattering patterns are characteristic of molecular para crystals with a significant degree of disorder.
Compared to B-DNA, the A-DNA form is a wider right-handed spiral, with a shallow, wide minor groove and a narrower, deeper major groove. The A form occurs under non-physiological conditions in partly dehydrated samples of DNA, while in the cell it may be produced in hybrid pairings of DNA and RNA strands, and in enzyme-DNA complexes. Segments of DNA where the bases have been chemically modified by methylation may undergo a larger change in conformation and adopt the Z form. Here, the strands turn about the helical axis in a left-handed spiral, the opposite of the more common B form. These unusual structures can be recognized by specific Z-DNA binding proteins and may be involved in the regulation of transcription.
What is an LNA? A locked nucleic acid (LNA), often referred to as inaccessible RNA, is a modified RNA nucleotide. The ribose moiety of an LNA nucleotide is modified with an extra bridge connecting the 2′ oxygen and 4′ carbon. The bridge “locks” the ribose in the 3′-endo (North) conformation, which is often found in the A-form duplexes. LNA nucleotides can be mixed with DNA or RNA residues in the oligonucleotide whenever desired and hybridize with DNA or RNA according to Watson-Crick base-pairing rules. Such oligomers are synthesized chemically and are commercially available. The locked ribose conformation enhances base stacking and backbone pre-organization. This significantly increases the hybridization properties (melting temperature) of oligonucleotides. LNA was independently synthesized by the group of Jesper Wengel in 1998, soon after the first synthesis by the group of Takeshi Imanishi in 1997. The exclusive rights to the LNA technology were secured in 1997 by Exiqon A/S, a Danish biotech company.
LNA nucleotides are used to increase the sensitivity and specificity of expression in DNA microarrays, FISH probes, quantitative PCR probes and other molecular biology techniques based on oligonucleotides. For the in situ detection of miRNA, the use of LNA is currently (2005) the only efficient method. A triplet of LNA nucleotides surrounding a single-base mismatch site maximizes LNA probe specificity unless the probe contains the guanine base of G-T mismatch.
Using LNA-based oligonucleotides therapeutically is an emerging field of biotechnology. The Danish pharmaceutical company Santaris Pharma a/s owns the sole rights to therapeutic uses of LNA technology and is now developing a new, LNA-based, hepatitis C drug called miravirsen, targeting miR-122, which is in Phase II clinical testing as of late 2010.
Definition of an LNA?
Locked nucleic acid (LNA) is a nucleic acid analogue containing one or more LNA nucleotide monomers with a bicyclic furanose unit locked in an RNA mimicking sugar conformation. LNA oligonucleotides display unprecedented hybridization affinity toward complementary single-stranded RNA and complementary single- or double-stranded DNA. Structural studies have shown that LNA oligonucleotides induce A-type (RNA-like) duplex conformations. The wide applicability of LNA oligonucleotides for gene silencing and their use for research and diagnostic purposes are documented in a number of recent reports, some of which are described herein.
What is an LNA?
LNA (Locked Nucleic Acids) are synthetic modified nucleic acids where the carbohydrate part of the nucleic acid has been synthetically changed. The modification results in an increased bonding strength between the DNA-bases in a double-helix when one of the DNA-bases has been modified. The overall result is a higher melting point of a DNA double-helix containing LNA-modified nucleic acids and thereby an increased stability. By designing the complementary DNA-strand in a double helix so it consists more or less of LNA-units, it is possible to regulate the rate of transcription – even to block it completely. In this way, it is possible to control the expression of genes and thereby the synthesis of selected proteins. The LNA technology is, therefore, a promising tool in the treatment of diseases which originate from genetic defects.
Ribonucleic Acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the letters G, U, A, and C to denote the nitrogenous bases guanine, uracil, adenine, and cytosine) that directs the synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.
Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling gene expression, or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis, a universal function where RNA molecules direct the assembly of proteins on ribosomes. This process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where ribosomal RNA (rRNA) then links amino acids together to form proteins.
Ribonucleic acid is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared to a copy from a reference book, or a template, because it carries the same information as its DNA template but is not used for long-term storage.
Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation.
RNA is synthesized from DNA by an enzyme known as RNA polymerase during a process called transcription. The new RNA sequences are complementary to their DNA template, rather than being identical copies of the template. RNA is then translated into proteins by structures called ribosomes. There are three types of RNA involved in the translation process: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
Although some RNA molecules are passive copies of DNA, many plays crucial, active roles in the cell. For example, some RNA molecules are involved in switching genes on and off, and other RNA molecules make up the critical protein synthesis machinery in ribosomes.
“Research on RNA has led to many important biological discoveries and numerous Nobel Prizes. Nucleic acids were discovered in 1868 by Friedrich Miescher, who called the material ‘nuclein’ since it was found in the nucleus. It was later discovered that prokaryotic cells, which do not have a nucleus, also contain nucleic acids. The role of RNA in protein synthesis was suspected already in 1939. Severo Ochoa won the 1959 Nobel Prize in Medicine (shared with Arthur Kornberg) after he discovered an enzyme that can synthesize RNA in the laboratory. However, the enzyme discovered by Ochoa (polynucleotide phosphorylase) was later shown to be responsible for RNA degradation, not RNA synthesis. In 1956 Alex Rich and David Davies hybridized two separate strands of RNA to form the first crystal of RNA whose structure could be determined by X-ray crystallography.”
What is meaning of RNA?
Ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
What is Definition of RNA?
RNA is a Ribonucleic Acid and is same copy of DNA (Deoxyribonucleic Acid).
What is RNA?
Ribonucleic acid or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”. Proteins are the workhorses of the cell; they play leading roles in the cell as enzymes, as structural components, and in cell signaling, to name just a few. DNA (deoxyribonucleic acid) is considered the “blueprint” of the cell; it carries all of the genetic information required for the cell to grow, to take in nutrients, and to propagate. RNA–in this role–is the “DNA photocopy” of the cell. When the cell needs to produce a certain protein, it activates the protein’s gene–the portion of DNA that codes for that protein–and produces multiple copies of that piece of DNA in the form of messenger RNA, or mRNA. The multiple copies of mRNA are then used to translate the genetic code into protein through the action of the cell’s protein manufacturing machinery, the ribosomes. Thus, RNA expands the quantity of a given protein that can be made at one time from one given gene, and it provides an important control point for regulating when and how much protein gets made.
For many years RNA was believed to have only three major roles in the cell–as a DNA photocopy (mRNA), as a coupler between the genetic code and the protein building blocks (tRNA), and as a structural component of ribosomes (rRNA). In recent years, however, we have begun to realize that the roles adopted by RNA are much broader and much more interesting. We now know that RNA can also act as enzymes (called ribozymes) to speed chemical reactions. In a number of clinically important virus’s RNA, rather than DNA, carries the viral genetic information. RNA also plays an important role in regulating cellular processes–from cell division, differentiation and growth to cell aging and death. Defects in certain RNAs or the regulation of RNAs have been implicated in a number of important human diseases, including heart disease, some cancers, stroke, and many others.
