Answer:
Four
Explanation:
During spermatogenesis, some diploid spermatogonia become larger in size and transform into primary spermatocytes. These diploid primary spermatocytes enter meiosis to produce haploid spermatids. One primary spermatocyte enters meiosis-I and produces two secondary spermatocytes. These secondary spermatocytes are haploids. Each of these two secondary spermatocytes enters the meiosis-II and produces two haploid spermatids. In this way, one diploid primary spermatocyte produces four haploid spermatids.

The sharks that live in the marine environment do not need to drink sea water unlike others.
This is because the concentration of the urea and oxide is trimethyl amine gets deposited in the tissues of the shark which is hyper osmotic condition to the outside environment( sea water).
There is an adequate amount of potassium, sodium and chloride in the body of shark.
This is how the shark maintains the osmoregulatory mechanism in marine environment.
