Answer:
The correct answer is option - d. Production of primary spermatocytes.
Explanation:
The accessory cells or supporting cells present within the seminiferous tubules of reproductive system termed as the Sertoli cells. They play various roles in the body and reproductive system.
Sertoli cells make blood-testis barrier in adjacent Sertoli cells in the seminiferous tubules. These cells secrete different types of enzymes and hormones such as inhibin which are also secreted by ovary and placenta in females. Sertoli cells produce seminiferous tubular fluid to provide nutrition to the sperm. Apoptotic germ cells are timely eliminated by these cells.
Thus, the correct answer is option D. Production of primary spermatocytes.
Imagining the illustration where a<span> pencil is beside a metric ruler, </span>scaled from 1 centimeter to 10 centimeters, with markings for millimeters between each number and o<span>ne end of the pencil is beside the 0 on the ruler, and the pencil point is midway between the 5 and 6, we can conclude that the precise and accurate measurement of the ruler would 5.5 centimeters. Since the point is pointing in the midway of 5 and 6, we can interpret that the point is pointing in the exact half between 5 and 6 thus we can conclude that this would be a 0.5 addition to 5, giving us the 5.5 cm.</span>

<span>This is true. Pioneer species are introduced to infertile soil so that the soil may become suitable for growing other plant species. These species do not rely heavily on soil; instead, they live on rocks and minerals. Moreover, they break down these rocks into soil so and eventually create a thicker layer of soil, allowing other plant species to inhabit the same region.</span>
