Nadusha1986 [10]

Answer:

C. disruptive natural selection

Explanation:

Disruptive selection is a type of natural selection in which extreme phenotypes are favored over intermediate phenotypes in a population. Environmental change is a major factor that can bring about disruptive selection. The individuals with the extreme phenotypes adapt well and are able to survive in the particular environment, while those individuals with intermediate phenotypes would hardly survive or be greatly reduced in number.

The gray rock outcrops and the brown soils of the Island favors the survival of mice with brown and gray fur color respectively. The fur colors of these two extreme phenotypes in the population of mice, have helped both varieties against Hawks as their main predators, hence establishing their existence on the Island.

If a person was unable to absorb nutrients from the large intestine, would this be lethal? What about if one could not absorb fr
Zolol [24]
It would in fact be lethal. The main function of the digestive system is just that, to digest food. Both intestines play an important part in the digestive system( to digest and absorb all nutrients possible from stomach contents) The function of the large intestine is to absorb water, left over nutrients from the small intestine and, electrolytes. It would be equally if not more deadly if the small intestine couldn’t absorb nutrients. Since the small I intestine also plays an important role with providing the body with nutrients and other vital materials it would be deadly if you could not absorb anything. You would go into a state of malnutrition and would need to be treated immediately.
