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:
<u>stonewort, and many green algae such as the Spirogyra.</u>
Explanation:
- As it was believed that the land algae were believed to be evolved from the stonewort plant and the blue-green algae like the cyanobacteria and the spirogyra that colonized the lands some 500 mn years ago was a freshwater alga.

Explanation:
Volume of oxygen used or Vo2 Max is the maximum ability of a person to consume oxygen and the ability of the heart, lungs and blood to transport the oxygen to other tissues and utilize it to produce ATP or energy during intense exercise.
Answer:
The value of control is a quantitative measure of the value of controlling the outcome of an uncertain variable. Decision analysis provides a means for calculating the value of both perfect and imperfect control. The former value, informally known as the value of wizardry, is an upper bound for the latter. Obtaining meaningful value-of-control measurements requires an awareness of important restrictions (concerning the nature of free will and the meaning of counterfactual statements) on the validity of this kind of analysis.
