Which hormone is responsible for the development of the male secondary sex characteristics? a)estrogen b)progestin c)progesterone d)testosterone

d)testosterone

Explanation:

Testosterone is the major male sex hormone and a steroid hormone that is produced primarily in the testes of the male. Testosterone is responsible for the development of the male secondary sex characteristics (such as the growth of facial and pubic hair, voice deepening, increased muscle and bone mass, and the beginnings of sex drive) during adolescence. This hormone stimulates the sperm production process in the testes, and it is also involved in the development of male reproductive tissues such as testes and prostate.

Testosterone is a hormone that is responsible for the development of male secondary sex characteristics.

Further Explanation:

Men are born with primary sex characteristics that differentiate females from a male; that is, a male has a penis and a female has a vagina. But after puberty, there is a development of secondary characters in males and also in females. Some secondary characteristic of males are:

•Pubic hair

•Narrow hip

•Muscular chest

•Heavier musculature

•Body hair

•Deeper voice

The testosterone is a hormone that is synthesized and secreted by the testes. The major function of this hormone is to regulate the development of the secondary characters of the male. They are also responsible for the production of red blood cells and the fertility of a male. If the level of testosterone in males is low, then it can lead to infertile conditions in men. As the age of an individual is increased, the level of testosterone decreases.

explanation:

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
