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:
conscious neural control
Explanation:
Neural control of digestive tract is unconscious achieved via the autonomic nervous system.
Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:
• The myenteric plexus – controls digestive tract motility
• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.
The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
processing information that is received from the stimuli receptors
sending out information so that the body can react appropriately to stimuli
coordinating reflexes and reactions to stimuli

B)
Explanation:
Natural selection describes how organisms change, and adaptation explains why. Charles Darwin, theory.
