Can cause acid rain because the chemicals mix with the water vapor
1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).
Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).
It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.
2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.
Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.
Nerve cells communicate by sending an electrical signal through an axon, from this molecules get released into the synapse this then binds itself onto receptor sites. With ion-linked channel receptors, the ligands get binded to a protein. The ion channels are then opened and the proccess gets repeated. Does that help?
Helicase breaks hydrogen bonds of the DNA helix. Therefore it “unzips” the DNA helix and separates the strands for free complementary RNA strands which use the strands as a template during replication.
