Why should deepwater shrimp on different sides of the isthmus have diverged from each other earlier than shallow-water shrimp?
Nataly_w [17]

Answer:

Reproductive isolation occurs faster in deep-water shrimp than shallow-water shrimp.

Explanation:

Though in the same territory, the blockage caused by the isthmus would quickly and permanently isolate shrimps living in the deeper parts of the water, thus making them unable to breed. This situation would then caused lack of gene flow within the deep-water shrimps , and the emergence of new species that are genetically different (diverge) from one another

The shallow-water shrimp, on the other hand, experience minimal isolation due to the shallowness of water, and could still breed with one another. Thus, they experience a relatively lower reproductive isolation

Suppose a star is undergoing a nuclear reaction. What happens to the elements around the star as it begins to emit more and more
kompoz [17]
The composition of a star is abundant in hydrogen and helium, both of which are two of the lightest elements. Because they are very light, they are usually unstable. To becomes stable, hydrogen atoms spontaneously combine with each other through a radiation process called nuclear fusion, to yield helium atoms. This process requires very high energy in the form of heat. Therefore, these lighter elements are burned in order to keep the star alive with energy.

Therefore, the answer is D.
