Biology is the natural science that studies life and living organisms , including their physical structure , chemical processes , molecular interactions , physiological mechanisms , development and evolution. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity , and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy [2] to maintain a stable and vital condition defined as homeostasis.

Branches of biology

Branches of Biology Biology , the scientific study of life , includes several relevant branches. Below is a list of major branches of biology with a brief description for each. Agriculture — science and practice of producing crops and livestock from the natural resources of the earth. Anatomy — study of the animal form , particularly human body Astrobiology — branch of biology concerned with the effects of outer space on living organisms and the search for extraterrestrial life.

Biochemistry — the study of the structure and function of cellular components, such as proteins, carbohydrates , lipids , nucleic acids, and other biomolecules , and of their functions and transformation s during life processes Bioclimatology — a science concerned with the influence of climates on organisms , for instance the effects of climate on the development and distribution of plants, animals, and humans Bioengineering — or biological engineering, is a broad-based engineering discipline that deals with bio-molecular and molecular processes, product design, sustainability and analysis of biological system s.

Biogeography — a science that attempts to describe the changing distributions and geographic patterns of living and fossil species of plants and animals Bioinformatics — information technology as applied to the life sciences, especially the technology used for the collection, storage , and retrieval of genomic data Biomathematics — mathematical biology or biomathematics is an interdisciplinary field of academic study which aims at modelling natural , biological processes using mathematical techniques and tools.

It has both practical and theoretical applications in biological research. Biophysics — or biological physics is an interdisciplinary science that applies the theories and methods of physical sciences to questions of biology Biotechnology — applied science that is concerned with biological systems, living organisms , or derivatives thereof, to make or modify products or processes for specific use Botany — the scientific study of plants Cell biology — the study of cells at the microscopic or at the molecular level.

Bios means life and logy means study. So, study of living organisms is called biology. It is a subdivision of science. Biology is a way of understanding nature. Biologists compare living and non living parts of world which affect the living things in any way. The meaning of biology is the study of life. It is difficult to define life.

biology. This branch also deals with the study of cell division. Taxonomy. Taxonomy is means the transmission of characters from one generation to another.

(General Science) BIOLOGY - Main Branches of Biology and Fields of Biology

The science which deals with the study of living objects and their life processes is called biology Greek words, bios — life, logos — study. It covers all aspect of the study of living creatures like occurrence, classification, ecology, economic importance, external form, organization, internal structure, nutrition, health and other body functions, reproduction, life history, inheritance and origin. Being broad — based and multi- disciplinary, the term biology is often replaced by the term life sciences or biological sciences.

So thank you for giving me a head start. Thanks for the web. I thank you for making me understanding the branches of biology and thank you so very much for this website.

Biology , study of living things and their vital processes. The field deals with all the physicochemical aspects of life. The modern tendency toward cross-disciplinary research and the unification of scientific knowledge and investigation from different fields has resulted in significant overlap of the field of biology with other scientific disciplines. Modern principles of other fields— chemistry , medicine , and physics , for example—are integrated with those of biology in areas such as biochemistry , biomedicine, and biophysics. Biology is a branch of science that deals with living organisms and their vital processes.

Он вспомнил факультетские заседания, лекции - все то, что заполняло девяносто процентов его жизни.

Он почувствовал, что сзади что-то произошло, возникло какое-то замешательство, и подумал о человеке, у которого купил пиджак. Беккер надеялся, что тот внял его совету не надевать пока пиджак. Он начал было вертеть головой, но испугался, что очки в тонкой металлической оправе только этого и ждут, и весь сжался, надеясь, что черный пиджак хоть как-то прикроет его брюки защитного цвета. Увы, это было невозможно. Чаша быстро приближалась к нему справа.

Смит поднял брови. - Выходит, выбор оружия был идеальным. Сьюзан смотрела, как Танкадо повалился на бок и, наконец, на спину. Он лежал, устремив глаза к небу и продолжая прижимать руку к груди.

 Успокойся, Грег. Сирена продолжала завывать. - Но я же ни в чем не виноват. - Ты лжешь.
