Question

Some animals can survive freezing, and others cannot. Which of the following is associated with the ability of animals to survive freezing?

A. High metabolic rate
B. Antifreeze proteins
C. Small body size
D. Nocturnal behavior

Answer 1

Animals that can survive freezing have adaptations such as antifreeze proteins, torpor, and insulation to cope with extreme temperatures.

Step-by-step explanation:

Animals that can survive freezing have adaptations that help them cope with extreme temperatures. One adaptation is the production of antifreeze proteins. These proteins prevent ice crystal formation in the tissues and help retain the integrity of the cells. Another adaptation is the ability to enter a state of torpor during hibernation or estivation. Torpor is a condition in which the metabolic rate is significantly lowered, allowing the animal to conserve energy and survive until more favorable conditions arise. Some animals also have insulation, such as fur or fat, which helps them maintain a constant body temperature.
