A) ecdysone levels increase
B) ecdysone levels decrease

Question

Quizplus · Accepted Answer

Molt-inhibiting hormone (MIH) normally acts to suppress the secretion of ecdysone, the hormone that triggers molting in arthropods. When the secretion of MIH is prevented, there is no suppression of ecdysone, leading to an increase in ecdysone levels, which in turn promotes molting.
