21. As the season turns from fall to winter, what is the most likely response that a wolf's body has to the changing season?

Wolf´s body stores energy in the form of fat tissues that also avoid heat loss

Explanation:

Many mammals living in cold climates, accumulate subcutaneous fat to survive during the winter season. In wolves, these fats provide energy and nutrients to support the winter season, which is the worst season for hunting. These fats are stored as adipose tissue that not only provides energy but also they provide thermal insulation (fatty tissue is known to be a poor heat conductor).
