Answer and Explanation:
In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:
- The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
- Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
- The metabolic rate falls so that the body generates less heat. You also become less active
- Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
The right answer is hyphae for the first gap, mycelium for the second gap.
The hyphae constitute the vegetative apparatus of the mushrooms, while the visible part, that which is improperly called mushroom, is in fact its reproductive apparatus.
Hyphae are less branched filaments consisting of a single cell that can be several centimeters long. They contain several nuclei and can sometimes be partitioned.
The mycelium is a part of the mushroom (composed by many hyphae), which is in the form of white filaments and grows about fifteen centimeters under the ground. It is this part of the mushroom that has therapeutic properties because the filaments of the mycelium are going to draw the minerals in the soil.

Answer:
The correct answer will be option-B.
Explanation:
Sertoli cells are the large somatic cells present in the testis which helps in the formation of spermatozoa. The Sertoli cells create a suitable environment for the production and maturation of the sperms as they produce certain molecules which nourishes the sperms.
The Sertoli cells act as a barrier between the testis and blood and secrete enzymes like inhibin. They eliminate the apoptotic germ cells and also produce seminiferous fluid to nourish the sperm. They do not play any role in primary spermatocytes.
Thus, Option-B is the correct answer.
