Question

phylum arthropoda insects have: 3 body sections head thorax 2 antennae 6 legs how does the arthropods exoskeleton help them? it allows them to swim better. it provides support and protection. it helps them to see better

Explanation:

Arthropods' exoskeleton is a hard outer structure. Swimming ability is related to appendages/body shape, not exoskeleton. Vision is related to eyes, not exoskeleton. The exoskeleton’s main roles are structural support (for body shape/movement) and protection (from predators, environment), so this option is correct.

Answer:

B. It provides support and protection.
