Question

Quizplus · Accepted Answer

Estradiol is primarily known for its role in the female reproductive system, where it stimulates the growth of the uterine lining during the menstrual cycle. This is an activational effect, as the hormone is acting on existing tissue to induce a specific response. The other choices either involve developmental effects (B, C, D) or effects not mediated by estradiol (E).
