The answer to this question is A. true. When aldosterone is produced, it helps regulate the levels of potassium in the blood by promoting potassium excretion through the kidneys. The mechanism behind this involves aldosterone binding to receptors in the cells of the kidney tubules, which leads to an increased reabsorption of sodium and an enhanced elimination of potassium. As a result, the levels of potassium in the blood decrease when aldosterone is produced.
