Question

Quizplus · Accepted Answer

The onset of puberty is regulated by the pituitary gland, which secretes hormones that stimulate the release of estrogen and testosterone. These hormones then trigger the development of secondary sexual characteristics in boys and girls.

Answer: D
 Inadequate nutrition can lead to malnourishment, which can adversely affect the timing of puberty. Research has shown that girls who experience poor nutrition or chronic stress may begin to enter puberty earlier than their peers. This is thought to be due to changes in the levels of hormones that regulate growth and development.
