Antidiuretic hormone (ADH) and the renin-angiotensin-aldosterone system (RAAS) work together in maintaining osmoregulatory homeo
julsineya [31]

Answer:

The correct answer will be- ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions.

Explanation:

To maintain the osmolarity of the blood in the human body, the body activates the RAAS pathway and the production of ADH.

RAAS pathway gets activated when the receptors sense low blood pressure in the body. This activates the production of renin from the juxtaglomerular cells of the body which converts the angiotensin to angiotensin I and later angiotensin II.

This allows the reabsorption of sodium ions in the blood through proximal and distal tubules in the nephron.  This activates the synthesis of aldosterone which increase the permeability to sodium ions.

The Antidiuretic hormone helps regulate the low blood pressure by adding aquaporins to the distal tubule membrane which help absorb the water.

Thus, ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions is the correct

Kruka [31]

Answer:

Option B, It increases the probability that some offspring will survive long enough to reproduce.

Explanation:

The larger the number of eggs, the larger will be the available opportunities for at least few of the youngsters to develop into adult being and survive till the age of fertility. This shall enhance the chances of producing new offspring before the older  one dies thereby replacing them without changing the population number and further producing offspring that can survive to replace them and continue this chain.

Hence, option B is correct
