Answer:
The Answer is likely D, none of the above because all of these would cause damage in any area, however, climate change is what deals the most damage to tropics due to the fact that the already hot tropical climate is getting even hotter, which can cause rivers and what not to dry out, whereas though climate change is a big problem around the world, it is least apparent in the southern hemisphere, and not nearly as apparent in the northern hemisphere when you compare it to research in the equatorial region.
(Please note that this answer is more of a matter of my own opinion than anything, and under most circumstances, none of the above would be wrong. Please do not hold it against me if this answer is wrong. If it is wrong, then the answer would probably be A)

Answer:
I'm not sure what the answers are but
Polar bears begin to eat goose eggs as a way to survive when seals, their usual prey, are not available.
Mountain goats restrict their range to higher altitudes because of warmer low-altitude temperatures.
Snowshoe hares change their fur from white to brown to match their warm summer habitats.
Early humans learn to make tools like flint arrows and knives to help them hunt more efficiently.
if these are your options then the answer is
C) Snowshoe hares change their fur from white to brown to match their warm summer habitats.
At the inner mitochondrial membrane<span>, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the </span>membrane<span>, through ATP synthase.</span>
