The question is incomplete. The complete question is as follows:
Which of the following is not true regarding fenestrated capillaries?
A) Fenestrated capillaries in endocrine organs allow hormones rapid entry into the blood.
B) Fenestrated capillaries in the small intestine receive nutrients from digested food.
C) Fenestrated capillaries are essential for filtration of blood plasma in the kidney.
D) Fenestrated capillaries form the blood-brain barrier.
Answer:
Fenestrated capillaries form the blood-brain barrier.
Explanation:
The fenesterated capillaries are small fine thin capillaries that helps in the exchange of substances. These capillaries are mainly found in the kidney, small intestine and glands.
The fenestrted capillaries allow the exchnage of hormone in the blood and in the kidney for the filtration. The nutrients can be easily exchanged by the capillaries present in the small intestine. The blood brain barrier function is not performed by the fenesterated capillaries. They allows the rapid exchange function and not as the barrier.
Thus, the correct answer is option (D).
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.
I think the correct answer from the choices listed above is option A. Cells divide in order to maintain a surface area large enough to support their cytoplasm. When they divide, their volume decreases which enables them to obtain enough nutrient and expel wastes.
