Explanation:
Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.
One reason is because the short days and long nights prevent the earth from warming up, another reason could be because the sun's rays in winter are more spread out thus minimizing the amount of energy
Explanation:
D. A change in the amount of polar ice will alter how ocean currents move.
An adaptation that makes bipedalism possible is the need to get around. If your slithering on the ground, you could get diseases, or get hurt.
