Which of the following is NOT an example of homeostasis?

Question

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
As humans age, they become more susceptible to disease and cancer.
d
When body temperature rises, nerve impulses cause sweat glands to release more sweat.

Answer 1

The option that is NOT an example of homeostasis is:

c) As humans age, they become more susceptible to disease and cancer.

Homeostasis refers to the mechanisms that maintain stable internal conditions in an organism despite changes in external conditions. The other options (a, b, and d) describe processes that help maintain homeostasis in response to various stimuli. Option c, however, describes a general trend related to aging rather than a specific regulatory mechanism that maintains internal stability.
