(C) its genetic diversity is very low.

<h3>What is meaning of Extinction?</h3>

Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction.

Determining this point is challenging because a species' potential range may be quite wide, and is typically done after the fact. Due to this problem, there are phenomena like Lazarus taxa, in which a species that was thought to be extinct suddenly "reappears" after a period of apparent absence (usually in the fossil record). Estimates place the number of extinct species at over five billion, or more than 99% of all species that have ever existed on Earth.

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
