During childbirth, a hormone produced by the pituitary gland causes muscles of the mother's uterus (or womb) to contract. the more contractions there are, the more hormone is produced.

which best explains why this occurs?

a. positive feedback is used to build more contractions.

b. positive feedback is used to lessen the effects of the contractions.

c. negative feedback is used to build more contractions.

d. negative feedback is used to lessen the effects of the contractions.

The correct answer is A.

Positive feedback is a regulatory mechanism, a type of feedback loop in which the stimulus generates a response that in turns acts as a stimulus  for the same response resulting in the amplification or exaggeration of the response.

The hormone oxytocin causes contractions of the uterine wall, and the contraction in turns causes the release of more oxytocin and thus contractions increase.

The answer is A
