Worked Solution

Step 1: Arctic environments are extremely cold. Step 2: Blubber is a layer of fat that acts as an insulator to trap body heat. Step 3: Small ears have less surface area, which reduces the amount of heat escaping to the surroundings.

Correct answer: The blubber reduces heat loss and the small ears reduce heat loss.
