ONLiNE UPSC · Accepted Answer

Statement 1 is correct : In colder environments, marine larvae develop at slower rates due to reduced protein synthesis and folding, which helps them conserve energy and better cope with limited resources.

Statement 2 is correct : Polar species generally have slower metabolic rates, allowing them to conserve energy and reduce their need for food, which is critical in environments with limited resources.

Statement 3 is correct : A rounded body shape helps reduce heat loss in polar animals by minimizing the surface area exposed to the cold environment, which is an essential adaptation for surviving extreme cold.
