This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism.
midparent value The mean of the two parental values for a quantitative trait in an individual offspring or in a specific cross. [8] migration mimicry The process by which an organism evolves to resemble another object, often an organism of another species. Mimicry can also occur between individuals of the same species.

[ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
Potter's work laid the foundation for global ethics, a discipline centered around the link between biology, ecology, medicine, and human values. [3] [4] Sargent Shriver, the spouse of Eunice Kennedy Shriver, claimed that he had invented the term "bioethics" in the living room of his home in Bethesda, Maryland, in 1970.

Biocentrism (from Greek βίος bios, "life" and κέντρον kentron, "center"), in a political and ecological sense, as well as literally, is an ethical point of view that extends equal inherent value to all living things. [1]
Examples of principles are, entropy in a number of fields, least action in physics, those in descriptive comprehensive and fundamental law: doctrines or assumptions forming normative rules of conduct, separation of church and state in statecraft, the central dogma of molecular biology, fairness in ethics, etc.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
