Answer:

An exoskeleton.

Explanation:

Tough outer shell of many insects is known as exoskeleton that represents an external skeleton. The exoskeleton provides protection and support to the insects body as they lack an internal skeletal system as higher organisms. In insects, it is made up of chitin.

Exoskeleton also plays role in sensing, feeding, excretion, and protection against desiccation in land insects.

Thus, the correct word to be filled in the blank is 'exoskeleton.'

The brain's psychological mechanisms and the behaviors they produce can largely be understood through Darwin's theories; the theories of natural and sexual selection have directed much of psychological research.

In general, scientists accept Darwin's theories but in specific fields, such as social psychology and neuroscience, scientists have formulated surprising explanations using Darwinian ideas.
