• Surface area octuples, volume quadruples.

• Surface area triples, volume six times.

What is the main reason a tiny elephant would freeze to death and a giant mouse would explode?

• Tiny animals have too much surface area to retain heat, while giant animals have too little surface area to release heat.

• Tiny animals have a slow metabolism, and giant animals have a fast metabolism.

• The number of cells changes drastically with size, affecting organ function.

• The square-cube law only applies to inanimate objects, not living beings.

How does the metabolic rate of an animal's cells generally change as the animal's size increases?

• The cells become more active to produce more energy.

• The cells become less active to produce less heat.

• The cells' activity remains the same regardless of animal size.

• The cells change their type to adapt to the new size.

What is a unique characteristic of the Etruscan Shrew's metabolism due to its small size?
