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.
Elicitor. In plant biology, elicitors are extrinsic or foreign molecules often associated with plant pests, diseases or synergistic organisms. Elicitor molecules can attach to special receptor proteins located on plant cell membranes. These receptors are able to recognize the molecular pattern of elicitors and trigger intracellular defence ...
The Rho family of GTPases is a family of small (~21 kDa) signaling G proteins, and is a subfamily of the Ras superfamily. The members of the Rho GTPase family have been shown to regulate many aspects of intracellular actin dynamics, and are found in all eukaryotic kingdoms, including yeasts and some plants. Three members of the family have been ...
Phylogenies showing the terminology used to describe different patterns of ancestral and derived character or trait states. [1] In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). [2][3][4] A synapomorphy is an apomorphy shared by two or more taxa ...
The internal environment (or milieu intérieur in French; French pronunciation: [mi.ljø ɛ̃.te.ʁjœʁ]) was a concept developed by Claude Bernard, [1] [2] a French physiologist in the 19th century, to describe the interstitial fluid and its physiological capacity to ensure protective stability for the tissues and organs of multicellular organisms.
The structure of the complex of sodium (Na +) and the antibiotic monensin A Structure of a potassium complex of a crown ether, a synthetic ionophore-ion complex. Biological activities of metal ion-binding compounds can be changed in response to the increment of the metal concentration, and based on the latter compounds can be classified as "metal ionophores", "metal chelators" or "metal ...
Telescoping generations. Telescoping generations can occur in parthenogenetic species, such as aphids or other life forms that have the ability to reproduce without ovum fertilization. [1] This occurrence is characterized by a viviparous female having a daughter growing inside her that is also parthenogenetically pregnant with a daughter cell.
Episome. An episome is a special type of plasmid, which remains as a part of the eukaryotic genome without integration. Episomes manage this by replicating together with the rest of the genome and subsequently associating with metaphase chromosomes during mitosis. Episomes do not degrade, unlike standard plasmids, and can be designed so that ...
