Verified by ExpertsD
Both Statement I and Statement II are correct.
When the animals feel cold, they curl their bodies to decrease the surface area of their bodies. As we know, the total energy radiated by body varies directly as the surface area of the body. Larger is the surface area, the loss of heat due to radiation is more and vice-versa.
