A) hibernation
B) aestivation
C) diapause
D) moulting
Correct Answer: A
Solution :
Hibernation is a state of inactivity and metabolic depression in mammals to escape cold weather and food shortage over the winter. In reptiles, it is called brumation. Aestivation is similar to hibernation. It is also a state of animal dormancy in which invertebrate and vertebrate animals enter to avoid damage from high temperatures. Diapause is a predictive strategy that is predetermined by an animals genotype. It is common in insects, mammals, etc. Moulting also known as sloughing, shedding or for some species, ecdysis, is the manner in which an animal routinely casts off a part of its body, either at specific times of the year or at specific points in its life cycle.
