Question 1:

Discuss metabolic scaling. Think about all factors that contribute to metabolism and how these

change with body size. For simplicity, use the prairie dog and bison as your examples.

Question 2:

Think about the organelles, the cells, and the tissues used in maintaining endothermic body

temperatures. How are these different in a slow-moving sloth versus a cheetah that need burst

of energy to chase prey?

Question 3:

Explain how the nervous system works. Start with the resting potential, describe a stimulus,

and continue until the signal has affected a motor neuron. Be very specific.

Question 4:

We have discussed the blubber in whales a few times. With regard to the topics discussed, how

does the breeding season fast affect whales and their blubber. Consider all physiological relevant topics
