Question 4

You are studying a large tropical reptile that has a high and relatively stable body temperature. How would you determine whether this animal is an endotherm or an ectotherm?

Accepted Answer

A) You know from its high and stable body temperature that it must be an endotherm. 
B) You know that it is an ectotherm because it is not a bird or mammal. 
C) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. 
D) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. 
E) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm. 
A) You know from its high and stable body temperature that it must be an endotherm.

Question 5

Hibernation and estivation during seasons of environmental stress are both examples of

Accepted Answer

A) acclimatization. 
B) torpor. 
C) evaporative cooling. 
D) nonshivering thermogenesis. 
E) shivering thermogenesis. 
A) acclimatization. 
B) torpor. 
C) evaporative cooling. 
D) nonshivering thermogenesis. 
E) shivering thermogenesis.

Question 6

-The horizontal arrows in the figure above show that

Accepted Answer

A) the warmer arterial blood can bypass the legs as needed, when the legs are too cold to function well. 
B) the warmer venous blood transfers heat to the cooler arterial blood. 
C) the warmer arterial blood transfers heat to the cooler venous blood. 
D) the arterial blood is always cooler in the abdomen, compared to the temperature of the venous blood in the feet of the goose. 
E) the goose's legs get progressively warmer as the blood moves away from the abdomen to the feet.
