Definition of Science Biology
Biology
or life (in English: Biology) (from the Greek: Bios Life and Logos science) is
the study of living organisms in terms of their structure, and feeding, and
reproduction, and the nature and characteristics, types, and the laws that
govern ways of life, evolution and interaction with the middle
natural.
And
biology is very wide and is divided into several branches of the most important
science microorganisms and zoology and botany, as well as physiology,
biochemistry and ecology. With
the advancement of science, since the nineteenth century, became a close links
to other sciences, both theoretical and applied, such as medicine, pharmacy and
other technical areas meet essential human needs and ongoing.
Handles
biology with the study of all forms of life, where cares characteristics of
organisms, classification and behavior, as taught how emergence of these species
to exist and mutual relations between each other and between them and their
environment, so the biology embraces within many disciplines and branches
independent scientific, but they all meet in
relation to living organisms (the phenomenon of life) to a wide range of types
and sizes begin studying viruses and bacteria and then plants and animals, while
concerned with other branches to study biological processes within the cell,
such as biochemistry to branches examining the relationships between the living
and the environment in ecology.
Membership
level, take biology undertook study phenomena birth, growth, aging aging, and
death death and decomposition of living organisms, not to mention the study
similarities between generations offspring and their parents (Genetics
heredity), as taught also plants and other phenomena that baffled
humanity through history.
Other
phenomena such as the secretion of milk lactation, metamorphosis, and lay eggs,
the recovery and healing, and Run out Tropism. Within
wider areas taught biologists hybridization of animals and plants, as well as
the diversity of the huge plant and animal life and (biodiversity biodiversity),
and the change in living organisms over time and evolution and the theory of
evolution and the phenomenon of extinction of some neighborhoods, or the
emergence of new types Speciation, as well as the study of social behavior among
animals ... etc..
Includes
biology botany that in examining the plants while animal science is the study
animals either anthropology فيختص study of the human being, and At the molecular
level, Life Vtders in molecular biology, biochemistry and molecular genetics.
At
the next level, namely cell He studies in cell biology.
And
when you go to the level of CR cells multicellular, appears to have science like
physiology and anatomy and tissue. The
growth Biology Developmental biology is the study of life in the level of
development and growth of individual organisms or so-called ontogeny.
But
when we move to more than one membership, highlights geneticist who studies how
the laws of heredity works heredity between parents and progeny. And
studying Alaathologia science Ethology behavior of the animal groups.
The
genetics Altgmaa Population genetics takes into account the entire gathering
Categories population. The
systematics Vtders areas multiple types of strains lineage (types of common
origin). Dynasets
interconnected relationships and habitats studied in the framework of Ecology
and Evolutionary Biology evolutionary biology. A
Biological Sciences is Astrobiology astrobiology (or xenobiology) who is
studying the possibility of the existence of extraterrestrial
life.
