Question

question 3 which of the following is an action of aldosterone? the release of renin that circulates in the blood it causes the kidneys to resorb na+ and therefore water it causes the release of angiotensin ii it causes the release of insulin growth factors (igfs)

Explanation:

Aldosterone is a hormone that acts on the kidneys. Its main function is to increase the re - absorption of sodium ions ($Na^+$) in the distal convoluted tubule and collecting duct of the nephron. Water follows sodium due to osmotic pressure, so water is also re - absorbed. Renin release is part of the renin - angiotensin - aldosterone system but not an action of aldosterone itself. Angiotensin II stimulates aldosterone release, not the other way around. Insulin growth factors are not related to aldosterone actions.

Answer:

it causes the kidneys to resorb Na+ and therefore water
