Question

question 9 of 10 which of these can develop only in females? a. oxytocin b. a testicle c. the pituitary gland d. a placenta

Explanation:

• Option A: Oxytocin is produced by both males and females (in the hypothalamus, released by pituitary), so not exclusive to females.
• Option B: Testicles are male reproductive organs, so they develop in males, not females.
• Option C: The pituitary gland is present in both males and females, developing in all individuals.
• Option D: The placenta develops during pregnancy, which only occurs in females (as they carry the fetus). So a placenta can only develop in females.

Answer:

D. A placenta
