Answer:
Vasopressin
Explanation:
Vasopressin is an anti-diuretic hormone. Its main function is to control the osmolality and volume of body fluids, helping the body to lose fluids. The secretory neurons are activated as a result of increased osmotic pressure or reduced blood pressure, which is also reduced by this hormone. The release of this hormone has a potent vasoconstrictor effect, causing water retention to increase, acting as an antidiuretic hormone. The increased permeability of the collecting tubules and the thick ascending branches of the Henle loop, resulting from the exposure of aquaporins to the apical membrane, enables the diffusion of water found in the tubule cells to the medullary region of the kidney.

Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.
