Question

Which of these best describes how an insect's exoskeleton is similar to a human skeleton?

A) It is attached to groups of muscles.
B) It is composed of the same materials.
C) It is capable of producing red blood cells.
D) It is periodically replaced by a new skeleton.​

Answer 1

The answer is A.

They are not composed of the same material. Insects’ Exoskeleton(IE) is chitinous, human skeleton(HS) isn’t. That cancels out option B.

The IE DOESNT produce RBCs. This is because Insects don’t have RBCs. Instead they have a fluid called HAEMOLYMPH. That cancels out option C.

Humans DO NOT undergo ecdysis( periodic shedding/replacement of old skeleton by nee skeleton). That cancels out option D.

I hope this explains it. You welcome!

Answer 2

Answer: D) It is periodically replaced by a new skeleton.

Explanation: The correct answer is D) It is periodically replaced by a new skeleton. An insect's exoskeleton serves a similar purpose to a human skeleton in providing support and protection, but unlike a human skeleton, an insect's exoskeleton is external and periodically shed and replaced as the insect grows.
