High genetic diversity and a large population can protect the lion population from being wiped out completely. Those lions whose genetics offer them protection from the virus may be immune. The small genetic diversity and low population of the cheetahs could leave the cheetah population with only a handful of immune individuals.
Answer:
Subduction zones are important for several reasons: ... Subduction zones drag down subducted oceanic sediments, oceanic crust, and mantle lithosphere that interact with the hot asthenospheric mantle from the over-riding plate to produce calc-alkaline series melts, ore deposits, and continental crust.
Explanation:
Natural selection is a process where organisms that are suited to a particular environment are better able to survive and reproduce than organisms that are not. On the other hand, artificial selection is the breeding of animals and plants to produce desirable traits (traits such as size or taste).
An example of artificial selection that is well known is the cross breeding of dogs.
Nature is responsible for natural selection, while humans are responsible for artificial selection.
