Question

Quizplus · Accepted Answer

Chitin and the cuticle form a protective barrier on the surface of the insect, which reduces water loss through evaporation. The tracheae and spiracles are respiratory structures, and the proteinaceous epidermis provides structural support and protection against foreign objects, but they do not have a direct role in reducing water loss. The alimentary canal is involved in digestion and absorption of nutrients and does not play a role in reducing water loss.
