← Nature & AnimalsWhich disruption results when ecdysone production fails in butterfly pupae?
A)Arrested differentiation of imaginal discs✓
B)Premature sclerotization of the exoskeleton
C)Lack of melanization post-eclosion
D)Impaired oxygen diffusion into tissues
💡 Explanation
Arrested differentiation occurs because the mechanism of ecdysone initiates development of imaginal discs during the pupal stage, therefore metamorphosis fails, rather than premature hardening or melanization, which are independent hormone-mediated processes.
