Hola!
Geographic Isolation prevents the cross breeding between the populations that have been separated by the isolation.
Without the separation the two growing population would be brought closer together and members of the two populations will cross breed.
♦ Example:
There are two populations of squirrels on either side of the grand canyon.

These populations are considered two different species.
We can conclude that these 2 populations were once one population.
Isolation allowed the two populations to move apart and speciation occurred.
hope it helps!
Answer:
A) hypertonic, out of the cell.
Explanation:
When cells are exposed to high levels of salt (sodium chloride) they lose water by osmosis and shrink. The cytoplasm condenses and the movement of cellular components, such as the cytoskeleton and organelles, stops. Cells adapt to high salt by quickly importing salt in order to attract water and regain volume, at the expense of increased salt concentration. Unlike cell volume, the movements of cellular components are slow to recover and, depending on the dose of salt, may not recover fully.
Answer:
Yes, but humans are slowly destroying it and recently there are a few species about to go extinct like polar bears
