What is the difference in the adaptation of a sled dog's (such as a Husky) thick coat of hair to help it withstand the cold temperatures of Arctic winters and a dog that adapts to cold temperatures in the fall by growing a thickened coat? The adaptation of the sled dog best describes adaptation at the ____________ level while the dog exposed to seasonal colder temperatures has _____________.
A) regional; natural selection at the individual level
B) individual; physiological modifications at the population level
C) population; physiological modifications at the individual level
D) species; natural selection at the population level
E) ecosystem; physiological modifications at the individual level

The adaptation of a sled dog's thick coat of hair to withstand the extreme cold temperatures of Arctic winters is an adaptation at the population level, as sled dogs have been bred specifically for their ability to thrive in cold environments. On the other hand, a dog that naturally grows a thicker coat during the fall season in response to colder temperatures is an individual level adaptation. This adaptation occurs through physiological modifications at the individual level, not through natural selection of the population as a whole. Therefore, the best answer choice is C: population; physiological modifications at the individual level.
