Correct answer: A. Grow larger in size
- A. Grow larger in size
- B. Protect against enemies
- C. Allow diffusion of gases
- D. Prevent from desiccation
Explanation
Arthropods need to molt, or shed their exoskeleton, because the rigid structure does not allow for growth. This process, known as ecdysis, enables them to grow larger in size. While the exoskeleton provides protection and helps in preventing desiccation, these are not the reasons for molting. Gas exchange occurs through other specialized structures and is not a reason for shedding the exoskeleton.

About Human Skeleton
The human skeleton provides support, protects organs, enables movement with muscles and stores minerals while bone marrow produces blood cells. Questions cover the axial and appendicular skeleton, types of bones and joints, cartilage, ligaments and tendons, and the difference between fixed, slightly movable and freely movable joints.
