amm1812

The hormone vasopressin stimulates the kidneys to retain water.

Vasopressin or antidiuretic hormone is secreted by the posterior pituitary gland and acts on the nephron tubules which increase the reabsorption of water, thus decreasing water content in urine while increasing that of blood.

The increase in water concentration in the blood elevates blood pressure as well as blood volume which makes the urine concentrated.

It regulates the tonicity of body fluids and therefore, in response to hypertonicity stimulates the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus restoring the tonicity of the body fluids toward normal.

A science club has 16 members. How many ways can a president, a vice president, and a treasurer be selected from the members?
boyakko [2]

Answer:

The answer would be D. 3,360

Explanation:

The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.
