Question

name the layer present in arthropods exoskeleton

Answer 1

The arthropods are covered with a tough, resilient integument or exoskeleton of chitin.

Answer 2

Answer:

The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss.
