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 ...
The yellow tail is a plesiomorphy and symplesiomorphy for all living species. In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy, all mean a ...
Rabbits are small mammals in the family Leporidae (which also includes the hares), which is in the order Lagomorpha (which also includes pikas).The European rabbit, Oryctolagus cuniculus, is the ancestor of the world's hundreds of breeds [1] of domestic rabbit and has been introduced on every continent except Antarctica.
A species is considered semelparous if it is characterized by a single reproductive episode before death, and iteroparous if it is characterized by multiple reproductive cycles over the course of its lifetime. Iteroparity can be further divided into continuous iteroparity (primates, including humans and chimpanzees) and seasonal iteroparity ...
In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits. Genetic changes include mutations, which are caused by damage or replication ...
Lens. Fresnel. Range. 22 nautical miles (41 km; 25 mi) Characteristic. 3 Fl R 15s. 1990 electrification. La Jument ("the mare") is a lighthouse in Brittany, Northwestern France. [1] The lighthouse is built on a rock (that is also called La Jument) about 300 metres from the coast of the island of Ushant.
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
Cell proliferation is the process by which a cell grows and divides to produce two daughter cells. [1][2][3][4] Cell proliferation leads to an exponential increase in cell number and is therefore a rapid mechanism of tissue growth. Cell proliferation requires both cell growth and cell division to occur at the same time, such that the average ...
