Question :
51. (p. 14) What positive feedback?
A. The body's ability : 1777289
51. (p. 14) What is positive feedback?
A. The body's ability to maintain homeostasis
B. The process the body uses to reverse the direction of movement away from homeostasis
C. The process the body uses to increase the movement away from homeostasis
D. The body's ability to function outside of the optimal range
52. (p. 15) All of the following are examples of positive feedback except:
A. sweating in response to elevated body temperature.
B. secretion of insulin in response to increased blood glucose.
C. secretion of glucagon in response to decreased blood glucose.
D. uterine contractions in response to the pressure of the baby's head on the cervix.
As the fetus reaches full term, its head pushes on the cervix. The increased pressure on the cervix causes the cervix to release prostaglandins, which cause the uterus to contract, moving away from homeostasis. The contractions cause the fetal head to push harder on the cervix which increases the pressure. The cervix responds by making more prostaglandins, leading to more contractions, further increasing the fetal head's pressure on the cervix.
53. (p. 15) Which of the following statements regarding homeostasis is false?
A. If the body detects a change and works to make the levels move even farther away from homeostasis, that is positive feedback.
B. If the body detects a change beyond its normal homeostasis range (either too high or too low), and it works to reach its homeostasis range by reversing the direction of movement; that is positive feedback.
C. Homeostasis is the body's ability to maintain a steady internal environment. This is achieved through using positive and negative feedback mechanisms.
D. Homeostasis is the body's ability to overcome an imbalanced internal environment. This is achieved through using positive and negative feedback mechanisms.
