Question 1

Which of the following would NOT be an example of negative feedback control in homeostasis?

Accepted Answer

A)  Blood volume and pressure drop due to minor bleeding.This decreased pressure causes the kidneys to increase water reabsorption to restore blood volume and pressure.
B)  Exposure to cold water causes body temperature to drop.Decreased stimulation of heat receptors causes constriction of blood vessels near the skin and better retention of heat.
C)  Glucose levels rise following consumption of a big dessert,triggering release of insulin which causes glucose levels to fall.
D)  During the birth process,stretch receptors in the uterus stimulate the release of oxytocin from the pituitary glanD.This hormone stimulates uterine muscle contraction that increases stimulation of the stretch receptors.
E)  Blood levels of glucose fall during sustained exercise,causing the release of glucagon which stimulates the release of glucose into the blood.F) None of the above
G) A) and B)

Accepted Answer

A)  positive feedback control.
