Answer;
Population; physiological modifications at the individual level.
The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
Explanation;
-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.
-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent. This adaptation best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
