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 ...
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
It was the No. 1 slang word used by teens in 2023, according to a survey of more than 600 parents by the language learning platform Preply. In the survey, 62% of parents said "sus" is the most ...
In behavioral ecology, a behavioral syndrome is a correlated suite of behavioral traits, often (but not always) measured across multiple contexts. The suite of traits that are correlated at the population or species level is considered the behavioral syndrome, while the phenotype of the behavioral syndrome an individual shows is their behavioral type.

Access Consciousness is an alternative medicine technique similar to a combination of phrenology, reiki, energy therepies and theraputic touch, where health and wellness can be improved by touching the 32 "Energy Bars" on a person's head. [69] Acupuncture – use of fine needles to stimulate acupuncture points and balance the flow of qi.
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
Alarm calls have been studied in many species, such as Belding's ground squirrels. Characteristic 'ticking' alarm call of a European robin, Erithacus rubecula. In animal communication, an alarm signal is an antipredator adaptation in the form of signals emitted by social animals in response to danger.
