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 ...
This glossary of cellular and molecular biology is a list of definitions of terms and concepts commonly used in the study of cell biology, molecular biology, and related disciplines, including genetics, biochemistry, and microbiology. [1] It is split across two articles:
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are linearly related.
In mathematics, a function is a rule for taking an input (in the simplest case, a number or set of numbers) [5] and providing an output (which may also be a number). [5] A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. [6]
This glossary of genetics and evolutionary biology is a list of definitions of terms and concepts used in the study of genetics and evolutionary biology, as well as sub-disciplines and related fields, with an emphasis on classical genetics, quantitative genetics, population biology, phylogenetics, speciation, and systematics.
Although the basic principles are fairly similar, the treatment of synonyms in botanical nomenclature differs in detail and terminology from zoological nomenclature, where the correct name is included among synonyms, although as first among equals it is the "senior synonym": Synonyms in botany are equivalent to "junior synonyms" in zoology.
Dependence receptors display the common property that they mediate two different intracellular signals: in the presence of ligand, these receptors transduce a positive signal leading to survival, differentiation or migration; conversely, in the absence of ligand, the receptors initiate and/or amplify a signal for programmed cell death.
Facultative means "optional" or "discretionary" (antonym obligate), used mainly in biology in phrases such as: Facultative (FAC), facultative wetland (FACW), or facultative upland (FACU): wetland indicator statuses for plants; Facultative anaerobe, an organism that can use oxygen but also has anaerobic methods of energy production. It can ...
