Answer 2

1: Puberty is when a child's body begins to develop and change as they become an adult.

2:In boys, the first puberty change is the enlargement of the scrotum and testes. At this point, the penis does not enlarge. As the testes and scrotum continue to grow, the penis grows. The first growth of pubic hair produces long, soft hair that is only in a small area around the genitals.

3: The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body (target site). In essence, hormones serve as messengers, controlling and coordinating activities throughout the body.

7: The most common cause of goiters worldwide is a lack of iodine in the diet. In the United States, where the use of iodized salt is common, a goiter is more often due to the over- or underproduction of thyroid hormones or to nodules in the gland itself.
