Insects Prevent Water Loss and Disturbance in the Osmotic Balance

Question

Insects prevent water loss and disturbance in the osmotic balance in cells by
A) having a water-proof cell wall around each cell.
B) having a cuticle that makes the body water-proof.
C) having an outer epidermis made of keratinized cells.
D) having equal concentration of molecules in ECF and ICF.

Accepted Answer

Insects have a cuticle, a protective, waxy or hard layer covering the epidermis of plants, fungi, and some invertebrates, including insects. This cuticle acts as a barrier to water loss, helping to prevent dehydration and maintain osmotic balance within their cells.
