Answer 1

Answer:

option 2

Explanation:

growth sprut is caused by pitiutary gland

Answer 2

Answer:

1)The increased secretion of testosterone from the testes during puberty causes the male secondary sexual characteristics to be manifested. In males, testosterone directly increases size and mass of muscles, vocal cords, and bones, deepening the voice, and changing the shape of the face and skeleton

2)During normal adolescent development in males testosterone induces the adolescent growth spurt, at least in part, by increasing GH production via an increase in the amplitude of the peaks of GH which are released, and not by increasing the frequency of GH pulses.
