Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Arthropod bodies are protected and supported by a(an)
A
internal skeleton
B
exoskeleton
C
circulatory system
D
vertebrae
Explanation: 

Detailed explanation-1: -The bodies of arthropods are supported, not by internal bones, but by a hardened exoskeleton made of chitin, a substance produced by many non-arthropods as well. In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor. It is produced by the “skin” and then hardens into a protective outer-covering.

Detailed explanation-2: -One advantage of an exoskeleton is that it covers and protects the internal body structures. Another benefit is the way the muscles attach to the exoskeleton, giving the arthropod support. An advantage for land arthropods is the waxy layer that prevents dehydration and keeps the body from drying out.

Detailed explanation-3: -The hard outer coverings of arthropods is a cuticle that acts as an exoskeleton. This exoskeleton protects from adverse environmental conditions and enemies.

Detailed explanation-4: -Arthropod and vertebrate skeletons are quite distinct from each other. Basically, the vertebrate skeleton is internal (an endoskeleton) while the arthropod skeleton is external (an exoskeleton).
