1. Which one of these statements is true about the way the metabolic rates of different species of animals have been observed to change with their body size?

a. The total metabolic rate declines with body length

b. The metabolic rate per gram of tissue declines with body mass

c. The total metabolic rate declines with body mass

d. he metabolic rate per gram of tissue increases with length

2. Which one of these statements is true about the way the metabolic rate of an individual ectotherm varies with increasing temperature? It...

a. Rises nonlinearly

b. Remains constant in the thermoneutral zone

c. Rises sharply and then drops gradually as temperature becomes stressfully hot

d. Fluctuates in a linear manner

3. Which one of these statements is false about the way the metabolic rate of an individual endotherm varies with environmental temperature? It...

a. Fluctuates in a non-linear manner

b. Starts high when temperature is very low, then drops to a minimum, before rising again as temperature becomes stressfully hot

c. Rises if body temperature decreases

d. Remains constant in the thermoneutral zone

4. Endotherms normally regulate a high and constant body temperature but can drop their body temperature over hours or months to save energy and water. This body temperature drop is called:

a. torpor

b. ectothermy

c. homeothermy

d. aestivation
