Answer :

Final answer:

Temperature-sensitive proteins influence fur color change in animals like arctic foxes and rabbits based on environmental temperatures.


Explanation:

Temperature-sensitive proteins play a crucial role in changing the fur color of certain animals, such as arctic foxes and rabbits, from white in winter to darker in summer. The protein product of the gene does not fold correctly at colder temperatures, resulting in the color change. This adaptation is advantageous to these species, allowing them to thrive in their respective environments.
