The question is incomplete as it does not have the options which are:
A. Merocrine gland
B. Apocrine gland
C. Salivary gland
D. Holocrine gland
Answer:
D. Holocrine gland
Explanation:
Exocrine glands are the organs or the subcellular structures which secrete a substance which is excreted out of the body.
The exocrine glands are different from the endocrine glands as their secreted products are released out of the body which is not in the case of endocrine glands.
The wax is secreted by the sebaceous glands by the production of cells that break along the base of the garland with substance into the ductal system by the exocrine glands called Holocrine glands.
Thus, Option-D is the correct answer.
Holocrine glands will release whole broken open cells into their ductal system. These cells contain the stores of substance to be released by the gland. This method of secretion requires frequent cell turnover and replacement.
Answer:
The correct answer is option C. "pleiotropy".
Explanation:
Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.
I believe it is E. Could be wrong though.<span />
A small amount of fat is an essential part of a healthy, balanced diet. Fat is a source of essential fatty acids, which the body can't make itself. Fat helps the body absorb vitamins A, D and E. These vitamins are fat-soluble, meaning they can only be absorbed with the help of fats.
