Question 6 Which of the following is NOT an example of homeostasis? a During rigorous exercise the heart rate increases to deliver more blood to the cells. b When blood glucose is high, the hormone insulin reduces blood glucose. C When body temperature rises, nerve impulses cause sweat glands to release more sweat. d As humans age, they become more susceptible to disease and cancer.

Answer 1

The correct answer is d.

The statement "As humans age, they become more susceptible to disease and cancer" is not an example of homeostasis. Instead, it describes a change in the body’s overall health and resilience as a function of aging.

The other options (a, b, and c) are examples of homeostasis, which is the body's ability to maintain stable internal conditions despite external changes.
