Question

question 12 (2 points) females are able to reproduce at the onset of ______.
a ejaculation
b endocrine
c pubic hair
d menstruation

Explanation:

To determine when females can reproduce, we analyze each option:

• Option a (Ejaculation) is a male reproductive function, so incorrect.
• Option b (Endocrine) refers to hormone - related systems, not the onset of female reproduction.
• Option c (Pubic hair) is a secondary sexual characteristic, not directly related to reproductive ability.
• Option d (Menstruation) marks the start of the menstrual cycle, which means the female reproductive system is mature enough for potential reproduction (ovulation occurs, enabling fertilization).

Answer:

d. Menstruation
