Question

if the Earth were to begin to enter another ice age, which of the following characteristics might help an animal survive?

Answer 1

Animals that could survive during an ice age would have characteristics such as adaptations to prevent heat loss, the ability to change behavior and adapt to new conditions, and physiological adaptations to cope with freezing temperatures.

Step-by-step explanation:

An animal that could survive during an ice age would have certain characteristics that would help it deal with the cold conditions. One key characteristic would be having adaptations to protect against heat loss, such as a layer of fat or thick fur. For example, polar bears have thick fur and a dense layer of fat to maintain body temperature. Another characteristic would be the ability to change behavior and adapt to new conditions, such as migrating to areas with more resources. Finally, some animals may have physiological adaptations, like producing antifreeze proteins or adjusting the composition of their cell membranes, to cope with freezing temperatures.

Answer 2

Not sure but i think living things adapt to their environment.
Adaptations are traits giving an organism an advantage in a certain environment. And variations of individuals is important for a healthy species. So i think adaptation might be the right answer because animal will try to adapt the certain environment. I hope this answer will help you.
