Answer:

B. differential reproductive success caused by genetic variation is necessary for the process of natural selection.

Explanation:

Natural selection is the process wherein individuals with adaptive genetic variations are favored. Genetic variations are present among the individuals of a population. Individuals with adaptive genetic variations survive more and reproduce to leave more progeny. Their progeny also carries the selected adaptive genetic variations.

Over the generations, the population evolves into a population with more number of individuals carrying those beneficial genetic variations.

Since natural selection favors the individuals with the genetic traits that make them better adapted to prevailing surroundings, it leads to the evolution of populations.

Renin hydrolyzes angiotensinogen, which is released from the _________, to form angiotensin i.
tia_tia [17]

Renin is an enzyme that helps control blood pressure and regulate levels of sodium and potassium in the body. Angiotensinogen is the hormone that causes the narrowing of blood vessels. It is released from liver to form angiotensin.

<h3>What is the role of angiotensin?</h3>

Angiotensinogen is a hormone that on hydrolysis forms angiotensin

Angiotensinogen is hydrolyzed by renin enzyme and forms angiotensin.

This angiotensin helps to increase blood pressure by the process of vasoconstriction,  increased aldosterone biosynthesis and renal actions.

Thus, it can be concluded renin hydrolyzes angiotensinogen, which is released from the liver, to form angiotensin.
