Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
The best description of predictable development of plant structure in an area over time is primary succession. The correct option is a.
<h3>What is succession?</h3>
Changes in the physical environment and the population of the species cause succession. There are two types of succession: primary and secondary succession.
Nudation, invasion, competition and coaction, reaction, and stabilization are the five stages of ecological succession. Autogenic succession is derived by biotic factor in an ecosystem.
Thus, the correct option is a. primary succession.

The major action of angiotensin II is C) increased vasoconstriction.
Angiotensin II is a vasoconstrictor and stimulates the adrenal cortex to supply aldosterone. Vasopressin is launched whilst osmoreceptors inside the hypothalamus are stimulated by means of hyperosmolarity.
The Parathyroid's fundamental function is to adjust calcium, phosphorus, and magnesium tiers via multi-organ impact
Even as angiotensin II is a part of the renin-angiotensin system, aldosterone manufacturing, and secretion by using the adrenal gland is simply stimulated by using angiotensin II so tiers boom and purpose renal reabsorption of sodium and multiplied blood volume.
