Answer:
Enzymes are biological molecules that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism
Explanation:
The correct answer is: Hares with a mutation that causes them to change color in response to temperature rather than day length
Since the climate is changing (as a consequence of global warming) temperatures are increasing more and more through the years. These changes affect populations, so they need to adapt to new environment conditions in order to survive. In this example above, mutations within snowshoe hares that will help them to change color in response to temperature rather than day length is very advantageous. Hares will be brown more often, because there are less and less colder temperatures and snow.
