← Nature & AnimalsWhich outcome occurs when a developing insect pupa's endocrine gland produces excess ecdysone?
A)Premature adult metamorphosis initiation✓
B)Arrested larval stage development
C)Delayed chitin hardening of exoskeleton
D)Inhibited imaginal disc differentiation
💡 Explanation
When excess ecdysone is produced, premature metamorphosis occurs because ecdysone triggers molting and differentiation processes, accelerating transition to the adult form. Therefore, premature adult metamorphosis is initiated, rather than larval arrest, delayed hardening, or inhibited imaginal disc activity, which require different hormonal imbalances or gene expression.
