← Nature & AnimalsWhich mechanism initiates exoskeleton shedding during molting stages?
A)Increased ecdysone hormone secretion✓
B)Decreased juvenile hormone sensitivity
C)Chitin synthase gene repression
D)Prothoracic gland apoptosis trigger
💡 Explanation
Increased ecdysone secretion triggers apolysis and ecdysis because these elevate enzymes dissolving the old cuticle (molting fluid), therefore, initiating shedding, rather than suppression of chitin or disruption of prothoracic secretions at this stage of metamorphosis.
