Changes in two hormones, _____ and estradiol, lie at the core of development in puberty.Multiple choice question.androdiolandrogencortisoltestosterone

The correct answer to fill in the blank is "testosterone."

Explanation

1. Testosterone is an important hormone that plays a key role in the development of male secondary sexual characteristics during puberty. It is produced primarily in the testes in males and in smaller amounts in females by the ovaries and adrenal glands.
2. Estradiol is a form of estrogen, which is critical for female development, but testosterone is the hormone that works alongside it to influence many aspects of puberty in both males and females.

In summary, changes in the hormones testosterone and estradiol are indeed central to the physical and sexual maturation associated with puberty.
