Commensalism. Remora are specially adapted to attach themselves to larger fish (or other animals, in this case a sea turtle) that provide locomotion and food. Commensalism is a long-term biological interaction ( symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. [ 1]
A family contains one or more genera. Intermediate minor rankings are not shown. Genus ( / ˈdʒiːnəs / pl.: genera / ˈdʒɛnərə /) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. [ 1] In binomial nomenclature, the genus name forms the first part ...
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 ...
Urinary casts are microscopic cylindrical structures produced by the kidney and present in the urine in certain disease states. They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy . They form via precipitation of Tamm–Horsfall mucoprotein ...
Surface of an organ facing away from the organ's axis, e.g. the lower surface of a lateral organ such as a leaf or petal. [ 2] Contrast adaxial. abort. To abandon development of a structure or organ. [ 3] abscission. Natural shedding of an organ that is mature or aged, as of a ripe fruit or an old leaf.
Intermediate minor rankings are not shown. In biological taxonomy, a domain ( / dəˈmeɪn / or / doʊˈmeɪn /) ( Latin: regio[ 1 ] ), also dominion, [ 2 ]superkingdom, realm, or empire, is the highest taxonomic rank of all organisms taken together. It was introduced in the three-domain system of taxonomy devised by Carl Woese, Otto Kandler ...
Category. v. t. e. Darwin's finches. Evolutionary biology is the subfield of biology that studies the evolutionary processes ( natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth.
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.
