Answer:
Spermatogenesis is stimulated by FSH acting on sertoli cells.
Explanation:
Spermatogenesis is the process by which spermatozoa grow and develop from germ cells into mature form. There are many hormones that are involved in this process and one of them is FSH (Follicle Stimulating Hormone). Another factor that play a vital role in the process are sertoli cells.
The FSH stimulates sertoli cells to release androgen-binding protein into the lumen portion of seminiferous tubules. The sertoli cells are the epithelial supporting cells that are located inside the seminiferous tubules. The sertoli cells are responsible for keeping the germ cells nourished and for extracting excess cytoplasm from newly formed spermatozoa cells just before they are released into the lumen of the seminiferous tublules.
So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck.
Answer:
Peptide Bonds
Explanation:
The bond that joins the amino acids to prepare long chain proteins are called 'Peptide bonds'.
Answer:
increase
Explanation:
when the energy intake is more than the energy required it tends to increase the weight of the person.
the basic fundamental is that we take energy from the food as intake of food is more and the calorie burn is less i.e. exercise is less as compare to the intake then this will lead to gain extra fat which will make the person obese.
