ZOO 101 Skeleton and Supporting Systems Objective Question

Question

Why do animals with a cuticle undergo moulting or ecdysis?
Options
A Because the cuticle is living and grows with the animal.
B Because the cuticle is a non-living substance that does not grow.
Correct Answer
C To change their color.
D To produce more chitin.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Chitin is a non-living substance, so the cuticle cannot grow. Animals with this type of skeleton must undergo moulting or ecdysis to shed the old cuticle and grow a new one.

Hint

They shed their outer covering to increase in size.
