B. Allostasis corrects disturbances in the body
C. Allostasis anticipates needs and avoids errors
D. Allostasis relies solely on negative feedback
5. What is basal metabolism?
A. The energy used to maintain a constant body temperature while at
rest

3. What strategies do endothermic animals use to cope with cold
environments?
4. Why is maintaining a constant core body temperature essential for
birds and mammals?
5. How does fever help the body fight infections, and what are the risks
associated with high fevers?
9.2 Thirst
Multiple choice questions
1. What is the primary function of vasopressin?
A. To decrease blood pressure by dilating blood vessels
