Ecdysone is_________________?
Correct answer: C. A hormone that regulates moulting in arthropods
- A. An enzyme that digest endocuticle during an arthropodal ecdysis
- B. A newly formed exoskeleton in authropods
- C. A hormone that regulates moulting in arthropods
- D. A process that involves moulting
Explanation
Ecdysone is a hormone produced by arthropods that initiates and regulates moulting by promoting changes in the old cuticle and development of a new one. The likely distractor is an enzyme digesting the endocuticle, but that is an enzymatic process associated with moulting, not the identity of ecdysone.

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.
