Rumex obtusifolius is a perennial herbaceous flowering plant that grows to a height of 40 to 150 cm (16 to 59 in). [2] It is easily recognizable by its very large oval leaves with cordate bases and rounded tips, some of the lower leaves having red stems. [2] The edges of the leaves are slightly "crisped" or wavy, the upper surface is hairless ...
Macromolecular docking is the computational modelling of the quaternary structure of complexes formed by two or more interacting biological macromolecules. Protein –protein complexes are the most commonly attempted targets of such modelling, followed by protein– nucleic acid complexes [1]. The ultimate goal of docking is the prediction of ...
Connexon. In biology, a connexon, also known as a connexin hemichannel, is an assembly of six proteins called connexins that form the pore for a gap junction between the cytoplasm of two adjacent cells. This channel allows for bidirectional flow of ions and signaling molecules. [1] The connexon is the hemichannel supplied by a cell on one side ...
Membrane channel. Membrane channels are a family of biological membrane proteins which allow the passive movement of ions (ion channels), water (aquaporins) or other solutes to passively pass through the membrane down their electrochemical gradient. They are studied using a range of channelomics experimental and mathematical techniques.
Rump (animal) The rump or croup, in the external morphology of an animal, is the portion of the posterior dorsum – that is, posterior to the loins and anterior to the tail. Anatomically, the rump corresponds to the sacrum. The tailhead or dock is the beginning of the tail, where the tail joins the rump. It is known also as the base or root of ...
White fish (Atlantic cod) White fish fillet (halibut – on top) contrasted with an oily fish fillet (salmon – at bottom)Whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly Atlantic cod (Gadus morhua), whiting (Merluccius bilinearis), haddock (Melanogrammus aeglefinus), hake (Urophycis), and pollock (Pollachius), among others.
Marine biology is a branch of biology. It is closely linked to oceanography, especially biological oceanography, and may be regarded as a sub-field of marine science. It also encompasses many ideas from ecology. Fisheries science and marine conservation can be considered partial offshoots of marine biology (as well as environmental studies).
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 and Mark ...
