The lemming is a small mammals with a very high daily energy expenditure for its size. Based on what you learned in the panda case study, what would you predict about the lemming?

A) It would have a very large brain, heart and kidney for its sizeB) It would be a very active animal. C) It would have a very high metabolic rate for its size. D) B and C only.

E) All of the above.

Answer: B and C only (Option D)

B. It would be a very active animal.

C. It would have a very high metabolic rate for its size.

Explanation:

Lemming is a mammal that has relatively small body size. Due to its small body size, it encounter issues when exchanging material from the extrinsic environment. Lemming's surface: volume ratio affects its energy consumption. It consumes higher energy at much rates compare to their body size.

However, more energy consumption is directly proportional to increased metabolic activities within the body system for lemming. Hence, the activeness of lemming is determined by the rate of catabolic and anabolic reactions that takes place in the body system for their respective life activities functions (e. g thermal control).
