positive feedback occurs when the hormone oxytocin stimulates ______ to increase the number and intensity of contractions during labor and delivery.
○ leutenizing hormones
○ progesterones
○ prostaglandins
○ estrogens

Explanation:

To solve this, we recall the role of oxytocin in labor. Oxytocin stimulates prostaglandins, which increase uterine contractions (positive feedback). Leutenizing hormones are for ovulation, progesterone maintains pregnancy, and estrogens have other roles in pregnancy but not direct contraction stimulation here.

Answer:

C. prostaglandins
