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:
Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.
Explanation:
Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.
Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.
