Which of the following is an example of positive feedback? Select one: a. Insulin stimulates cells to absorb glucose, which inhibits the release of insulin. b. Oxytocin causes uterine contractions during childbirth, which causes more oxytocin to be released from the posterior pituitary. c. The release of thyroxine from the thyroid causes the anterior pituitary to stop releasing TSH. d. When calcitonin from the thyroid causes blood calcium levels to decrease, PTH is released from the parathyroid to increase blood calcium levels.
