Answer 1

Aldosterone promotes sodium retention in the kidneys and is secreted in response to elevated levels of potassium in the blood.

Step-by-step explanation:

Aldosterone is a hormone secreted by the adrenal cortex in response to certain conditions. It promotes the reabsorption of sodium in the kidneys, helping to retain sodium and water and increasing blood volume and blood pressure. It is also released in response to elevated levels of potassium in the blood. Therefore, the correct answer is option e. A and B only. Aldosterone is a hormone secreted by the adrenal cortex in response to certain conditions. It promotes the reabsorption of sodium in the kidneys, helping to retain sodium and water and increasing blood volume and blood pressure.
