Biological Phenomena

Medical Definition:	Biological functions and activities at the organic and molecular levels in humans, animals, microorganisms, and plants. For biochemical and metabolic processes, BIOCHEMICAL PHENOMENA is available.
Guide Notes:	GEN or unspecified; prefer specifics; BIOCHEMICAL PHENOMENA is also available

Biological Phenomena Categories.

	Adaptation, Biological - Changes in biological features that help an organism cope with its ENVIRONMENT. These changes include physiological (ADAPTATION, PHYSIOLOGICAL), phenotypic and genetic changes.
	Biogenesis - The origin of life. It includes studies of the potential basis for life in organic compounds but excludes studies of the development of altered forms of life through mutation and natural selection, which is EVOLUTION.
	Eutrophication - Growth of a superabundance of algae and other microscopic plant life usually from an enrichment of a natural body of water by the addition of dissolved nutrients, especially nitrogen and phosphorus. It may be natural, induced (water pollution), or controlled (harvesting phytoplankton for food in an aquaculture system).
	Evolution - The process of cumulative change over successive generations through which organisms acquire their distinguishing morphological and physiological characteristics.
	Host-Parasite Relations - The interactions between two organisms, one of which lives at the expense of the other.
	Microbiologic Phenomena - Physiological processes and activities of microorganisms, including archaea, bacteria, rickettsia, viruses, protozoa, and fungi.
	Recovery of Function - A partial or complete return to the normal or proper physiologic activity of an organ or part following disease or trauma.
	Regeneration
	Remission, Spontaneous - A spontaneous diminution or abatement of the symptoms of a disease.
	Symbiosis - The living together of organisms of different species.
	Tissue Survival - The span of viability of a tissue or an organ.
