Question

Thirteen-year-old Grace's blood tests indicate that her levels of testosterone are about twice as high as they were a few years ago and that her estradiol levels are about eight times higher than earlier. This indicates that Grace is most likely to

A) undergo normal pubertal changes.
B) be depressed and show extreme behavior.
C) develop abnormal male physical characteristics.
D) develop abnormal female physical characteristics.

Answer 1

Grace is most likely undergoing normal pubertal changes as indicated by the increase in testosterone and estradiol levels.

Step-by-step explanation:

The changes in Grace's hormone levels, specifically the increase in testosterone and estradiol, indicate that she is most likely undergoing normal pubertal changes.

During puberty, the pituitary gland signals the testes to secrete testosterone in boys and the ovaries to secrete estrogen in girls. These hormones are responsible for the development of secondary sexual characteristics.

Since Grace's hormone levels are within the range expected during puberty, it suggests that she is experiencing normal physiological changes associated with puberty.
