Answer:
The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. ... 6,331 groups of genes common to all living animals have been identified; these may have arisen from a single common ancestor that lived 650 million years ago in the Precambrian.
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

The aerodynamic shape and lightness of the blue shark body allow it
to move “elegantly” across the oceans. It exhibits countershading like
many other sharks. The upper part is an indigo blue tone while the
ventral and the sides are white.
It has a long caudal heterocercal fin. The second dorsal fin measures
almost half the size of the first and its pectoral fins are unusually
long compared to other sharks. Its eyes are large, its teeth are
triangular, and it has a conical snout.
It reaches a length ranging from 3.8 to 4 meters and weighs about 240
kilograms. This species presents slight sexual dimorphism since the
female tends to measure little more than 1 meter in comparison with the
male.
