Water Loss from Insect Surface is Minimal Due to Which

Question

Water loss from insect surface is minimal due to which of the following structures?
A) a small surface area/volume relationship
B) a proteinaceous epidermis
C) chitin and the cuticle
D) tracheae and spiracles

Accepted Answer

Chitin and the cuticle provide a waterproof barrier that reduces water loss from the insect's surface. A small surface area/volume relationship may also help reduce water loss, but it is not as significant as the role of chitin and the cuticle. A proteinaceous epidermis and tracheae and spiracles are not directly related to water loss prevention from the surface.
