Answer;
A) island forms and mainland forms descended from common ancestors.
Explanation;
-Islands tend to host very distinct but limited sets or species; on a given island a spectacular collection of one related group of species would be present and thriving, but many entire families or even higher taxa would be completely absent.
-All the species on the islands and the nearest continent are closely related to one another, however, each species had a set of adaptations that suits it for a particular environment. This means that the island forms and mainland forms descended from common ancestors.
Answer:
striated
Explanation:
skeletal muscle: The voluntary muscle of vertebrates, which is striated and anchored by tendons to bone, is used to effect skeletal movement such as locomotion.
Answer:
The correct answer is D. interspecific competition
Explanation:
Niche overlap occurs when two species share a same niche and use the same resource. So niche overlap most frequently leads to competition between these two species called interspecific competition.
So In interspecific competition, the individuals of two different species fight for the same resource present in their niche for their survival. For example, lions and leopard share the same niche because they prey on similar types of animals like deer, wild pigs, etc.
So here niche overlap lead to the competition between these two carnivores. In interspecific competition, one species is more successful than other.
