Importance of Biology in Human Life

Biology is the science of life. It is the study of living systems. Biology is considered with life and characteristics of life. It includes study of cellular organization, development, growth, response to stimuli, metabolism, and reproduction.

Let us try and understand the importance of biology in human life in the following.

Important reasons for studying biology are to understand how cells and organisms work. It involves the study of life and it is very important as it tells us about the natural world. Biology tells us about our body, helping us to develop cures and treatments for many diseases. It also tells us about the bodies of other animals and it can provide clinical treatment for farm animals and also pets.

Biology also tells us about plants and how they can be beneficial to human life. Biology gives us a method to classify animals and help us understand animals. It also tells us do's and don’ts for our planet. It gives us a thorough picture of human body and the organisms inside us, also about the metabolism and other processes inside the human body. Biology also tells us about the behavioral acts of humans and animals.

Biology as a science helps human life in many ways. It helps in increasing production of food, combating diseases and also aids in protecting and conserving our environment. The advances in the field of biology have resulted in high standard of living in the field of food and health. Production of plants has been increased by improving the varieties and development of high-yield and diseases resistant varieties of plants and animals that are used as food.

Biology is the study of living things that are basically of two categories plants and animals. Importances of plants in human life are: plants are useful to human life and hence there is necessity in carrying out studies and to also to find more benefits from them. Plants are used as food like beans, rice, wheat, potatoes, etc; as medicine, and also for shelter. Wood is used for roofing, furniture, plants help in air purification. We study animals as we live together with animals, to understand their behavior and benefits to human life. Some types of animals are also an important source of food.

Biology is an important area of study as it reveals the facts and has taken us where we are today. All the other fields of study are dependent on the facts that are revealed by the studies that are carried out in field of biology.

life although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction. Protozoa perform, in a single cell, the same life functions as those carried on by the complex tissues and organs of humans and other highly developed organisms. The attributes of life are inherent in such minute structures as viruses, bacteria, and genes, just as they are in the whale and the giant sequoia. In seeking an understanding of life, scientists have broken down many barriers that once separated the physical sciences from the biological sciences; a result of the growth of biochemistry, biophysics, and other interrelated fields of study has been a better understanding of the composition and functioning of living tissues of all kinds. Characteristics of Life Organization is found in the basic living unit, the cell , and in the organized groupings of cells into organs and organisms. Metabolism includes the conversion of nonliving material into cellular components (synthesis) and the decomposition of organic matter (catalysis), producing energy. Growth in living matter is an increase in size of all parts, as distinguished from simple addition of material; it results from a higher rate of synthesis than catalysis. Irritability, or response to stimuli, takes many forms, from the contraction of a unicellular organism when touched to complex reactions involving all the senses of higher animals; in plants response is usually much different than in animals but is nonetheless present. Adaptation, the accommodation of a living organism to its present or to a new environment, is fundamental to the process of evolution and is determined by the individual's heredity. The division of one cell to form two new cells is reproduction; usually the term is applied to the production of a new individual (either asexually, from a single parent organism, or sexually, from two differing parent organisms), although strictly speaking it also describes the production of new cells in the process of growth. The Basis of Life Much of the history of biology and of philosophy as related to biology has been marked by a division of thought between vitalistic (or animistic) and mechanistic (or materialistic) concepts. In the most antithetic interpretations of these concepts, the vitalistic school maintains that there is a vital force that distinguishes the living from the nonliving and the mechanistic school holds that there is no essential difference between the animate and inanimate and that all life can be explained by physical and chemical laws. Such diametrically opposed views have actually seldom been held by investigators of either school; elements of both are usually involved. The animistic school, largely predicated on the inexplicability of the basic phenomena of life, has been greatly overshadowed by the accumulating weight of scientific data. As more and more is learned of the minute details of the structure and composition of the substances that make up the cell (to the extent that some have been synthesized chemically), it has become increasingly apparent that living matter is made up of the same (and only those) elements found in inorganic material, except that they are differently organized. The Origin of Life Fundamental religious concepts center around special creation and belief in the infusion of life into inanimate substance by God or another superhuman entity. On the other hand, many scientists have hypothesized that during an early geological period there gradually formed in the atmosphere increasingly complex organic substances composed of available inorganic compounds and water, utilizing ultraviolet rays and electrical discharges as energy sources. At a certain stage they formed a diffuse solution of "nutrient broth." Then in some way they were drawn together and developed the capacity for self-renewal and self-reproduction. In 1953, S. L. Miller synthesized several of the most basic amino acids in a glass flask by introducing an electrical discharge into an atmosphere of water vapor and some simple compounds thought to have been present naturally at the time when life first developed on earth. A more recent theory now widely held is that life originated in a volcanic setting more than 3.5 billion years ago, perhaps in hot deep-sea vents, utilizing a biochemistry based largely on sulfur and iron. The theory that life on earth came in a simple form from another planet has had small currency, although the discovery by Melvin Calvin of molecules resembling genetic material in meteors has given it some force.

Question:importance of studying chemistry and its contribution to human resources in terms of: 1. providing energy 2. promoting health 3. feeding the world 4. clothing the world 5. change the quality of human life

Answers:Well, there you go. That pretty much sums it up.

Question:I've grown up in L.A. and I am so sick of it now, yet as a musician I feel like I should stay here. At the same time thre are so many other places to go and see and experience life in, and with the music industry changing there really is not too much of a reason to stay here. Is it important to try life in a new city in order to make that step as an individual?

Answers:It is possible to grow as a person anywhere, by reading, and by taking an interest in the people and the world around you. But it is much easier to grow if you travel, just as it is easier to learn more about the world by eating many different foods or listening to lots of different music than it is to do so by eating noodles and listening to the same Sonic Youth album every day.

Vitamins And Their Importance :Check us out at A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. The term vitamin was derived from "vitamine," a combination word from vita and amine, meaning amine of life, because it was suggested that the organic micronutrient food factors which prevented beriberi and perhaps other similar dietary-deficiency diseases, might be chemical amines. This proved incorrect for the micronutrient class, and the word was shortened. Today, a chemical compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Thus, the term is conditional both on the circumstances and the particular organism. For example, ascorbic acid (vitamin C) is a vitamin for humans, but not for most other animals, and biotin and vitamin D are required in the human diet only in certain circumstances. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but are otherwise required less often. Vitamins are classified by their biological and chemical activity, not their structure. Thus, each "vitamin" refers to a number of vitamer compounds that all show the biological activity associated with a particular vitamin. Such a set of chemicals are grouped under an alphabetized vitamin "generic descriptor" title, such as "vitamin ...
