Answer:
C
Explanation:
Arrow 1 represents the promoter for RNA II.
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.
Metamorphic rock; because a rock that has added heat or pressure is metamorphic because it’s been chemically and physically changed
The answer is Taiga
Hope this helps:D
