(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.

There is no element with one valence electron and six energy levels. Only two valence electrons and six energy levels.
Answer:
Calcium
Explanation:
A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.

The answer to this question is option D
Answer:
Consider the arteriolar end of a capillary bed. During capillary exchange, the process of <u>filtration </u>is favored at the arteriolar end due to the higher <u>hydrostatic</u> pressure.
Explanation:
The <u>net filtration pressure</u> at the arteriolar end of the capillary bed is more than 10mmHg. That is why the fluid exits capillary since <u>capillary hydrostatic pressure</u> is 35mmHg that is greater than <u>blood colloidal osmotic pressure</u> which is 25mmHg.
Hence during capillary exchange, the process of <u>filtration </u>is favored at the arteriolar end due to the higher <u>hydrostatic</u> pressure.
