4.  secretion of aldosterone

5. sodium reabsorbed from distal tubules and collecting ducts

Explanation:

The RAAS pathway or Renin-angiotensin II-aldosterone pathway gets activated in the human body to maintain the osmolarity and blood volume.

When the receptors in the blood sense the low volume of water in the body sends signals to the brain which activates the secretion of the renin from the juxtaglomerular cells. Renin helps converts the inactive angiotensin to angiotensin I and II which help reabsorption of sodium ions. This activates the production of aldosterone which increases the reabsorption of the sodium ions into distal and collecting ducts.

How does crystal size compare in extrusive vs. intrusive rock? Explain the cause of this difference
Ede4ka [16]
The difference between extrusive and intrusive rocks are how they cool down. Extrusive rocks cool down quickly and are created by lava; because of this they have very small, fine-grained crystals. Intrusive rocks cool slowly beneath the surface of the earth and are created by magma; because the cooling process is very slow the rocks have very large crystals.
