Answer 2

Answer:

here is answer

Explanation:

Boys. In boys, the first puberty change is the enlargement of the scrotum and testes. At this point, the penis does not enlarge. Then, as the testes and scrotum continue to enlarge, the penis gets longer. Next, the penis will continue to grow in both size and length.

Girls. In girls, the first puberty change is the development of breast buds. This is when the breast and nipple elevate. The dark area of skin that surrounds the nipple of the breast (the areola) gets larger at this time. The breasts then continue to enlarge. Over time, the nipples and the areolas will rise again. They then form another mound on the breasts. When a girl becomes an adult, only the nipple is raised above the rest of the breast tissue.

Both boys and girls. Pubic hair development is similar for both girls and boys. The first growth of hair produces long, soft hair that is only in a small area around the genitals. This hair then becomes darker and coarser as it continues to spread. Over time the pubic hair looks like adult hair, but in a smaller area. It may spread to the thighs. It sometimes goes up the stomach.
