Homeostasis is the maintenance of internal stability. Options a, c, d describe regulatory mechanisms to stabilize body temperature, blood glucose, and blood delivery, respectively. Option b (aging increasing disease susceptibility) is a natural decline, not homeostasis.

Answer:

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