Question

which of the following is consistent with homeostasis? a decreases in blood pressure cause a corresponding decrease in heart rate b as body temperature rises, sweating occurs to cool the body. c elevated blood glucose levels cause insulin secretion to decline d as blood pressure falls, blood flow to the heart decreases e when a person drinks large quantities of water, urine output decreases to raise blood volume

Explanation:

Homeostasis is the body's ability to maintain a stable internal environment. When body temperature rises, sweating is a negative - feedback mechanism that cools the body and helps maintain a stable temperature. A decrease in blood pressure should typically cause an increase in heart rate to maintain blood flow (not a decrease as in A). Elevated blood glucose levels should cause an increase in insulin secretion to lower glucose levels (not a decline as in C). When blood pressure falls, the body tries to increase blood flow to the heart, not decrease it (not D). When a person drinks a large quantity of water, urine output should increase to maintain fluid balance, not decrease (not E).

Answer:

B. As body temperature rises, sweating occurs to cool the body.
