what is biology?

Question

such cells and nitrustion and also what else things biology is

Answer 1

Biology (from Greek βίος λόγος, see below) is the branch of science dealing with the study of living organisms. It is concerned with the characteristics, classification, and behaviors of organisms, how species come into existence, and the interactions they have with each other and with the natural environment. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. However, together they address phenomena related to living organisms (biological phenomena) over a wide range of scales, from biophysics to ecology. All concepts in biology are subject to the same laws that other branches of science obey, such as the laws of thermodynamics and conservation of energy.



Biology studies the variety of life (clockwise from top-left) E. coli, tree fern, gazelle, Goliath beetleAt the organism level, biology has partially explained phenomena such as birth, growth, aging, death and decay of living organisms, similarities between offspring and their parents (heredity) and flowering of plants which have puzzled humanity throughout history. Other phenomena, such as lactation, metamorphosis, egg-hatching, healing, and tropism have been addressed. On a wider scale of time and space, biologists have studied domestication of animals and plants, the wide variety of living organisms (biodiversity), changes in living organisms over many generations (evolution), extinction, speciation, social behaviour among animals, etc.

While botany encompasses the study of plants, zoology is the branch of science that is concerned about the study of animals and anthropology is the branch of biology which studies human beings. However, at the molecular scale, life is studied in the disciplines of molecular biology, biochemistry, and molecular genetics. More fundamental than these fields is biophysics which deals with energy within biological systems. At the next level, that of the cell, it is studied in cell biology. At the multicellular scale, it is examined in physiology, anatomy, and histology. Developmental biology studies life at the level of an individual organism's development or ontogeny. Moving up the scale towards more than one organism, genetics considers how heredity works between parent and offspring. Ethology considers the behaviour of organisms in their natural environment. Population genetics looks at the level of an entire population, and systematics considers the multi-species scale of lineages. Interdependent populations and their habitats are examined in ecology and evolutionary biology. A speculative new field is astrobiology (or xenobiology), which examines the possibility of life beyond the Earth.

Molecular biology is the science of study of biology at the molecular level.
William Astbury in Nature described molecular biology as:

"... not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan. It is concerned particularly with the forms of biological molecules and ..... is predominantly three-dimensional and structural - which does not mean, however, that it is merely a refinement of morphology - it must at the same time inquire into genesis and function" (W.T. Astbury, Nature 190, 1124. 1961)

Molecular biology has allowed us to uncover the mysteries of the human body, viruses, bacteria and all other life. As such, it has allowed the progress of medicine to advance to such a degree so that we may begin to cure the previously incurable, and to eventually find cures for every disease that afflicts human kind.

Molecular biology depends not only on biology but also chemistry, genetics, and biochemistry. The understanding of the interactions between DNA, RNA, proteins and lipids is vital in understanding how cells work and how diseases affect these interactions. Researchers and scientists are slowly piecing together these interactions and how each biological molecule functions. By understanding this, scientists can then examine disease conditions, and see if the function of any of the molecules has changed. If a molecule or interaction is affected by disease, scientists can then create therapies which target these alterations and repair them.

In conclusion, molecular biology is a vital field in our advancement of medicine and technology. By understanding how biological molecules interact and function, we will be able to not only gain an appreciation of the workings inside the cell, but also it will allow us detect and to fix any problems that arise during disease states.

Answer 3

Biology is the science of life. Biologists study the structure, function, growth, origin, evolution and distribution of living organisms. There are generally considered to be at least nine “umbrella” fields of biology, each of which consists of multiple subfields.

Biochemistry: the study of the material substances that make up living things
Botany: the study of plants, including agriculture
Cellular biology: the study of the basic cellular units of living things
Ecology: the study of how organisms interact with their environment
Evolutionary biology: the study of the origins and changes in the diversity of life over time
Genetics: the study of heredity
Molecular biology: the study of biological molecules
Physiology: the study of the functions of organisms and their parts
Zoology: the study of animals, including animal behavior

Adding to the complexity of this enormous idea is the fact that these fields overlap. It is impossible to study zoology without knowing a great deal about evolution, physiology and ecology. You can’t study cellular biology without knowing biochemistry and molecular biology as well.

Answer 4

Biology is just the study of living organisms

Answer 5

Biology is the study of Life.

Answer 6

Biology is the study of Living thing .
living thing are plants and animal.we
call plants and animals Living Organisms.

Answer 7

Biology is the study about living organisms,including human ,animal ,plant,microorganism,and insects

Answer 8

Biology comes from two Greek words "bios" means "life" and "logos" means study, so literally it is the study of life. It is a science concerned with studying any aspects of life including the animal, plants, and other living creature.

Answer 9

The word biology is derived from the greek words /bios/ meaning /life/ and /logos/ meaning /study/ and is defined as the science of life and living organisms.
