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.
