← Nature & AnimalsMetamorphosing insects undergo precisely timed molts; which consequence arises when a mutation delays ecdysone production during larval stages?
A)Premature pupation occurs independently of size
B)Increased larval size despite stage extension✓
C)Accelerated imaginal disc programmed apoptosis
D)Uniformly reduced juvenile hormone concentration
💡 Explanation
Delayed ecdysone causes extended larval feeding which increases larval size because molting inhibition depends on constant juvenile hormone signals, therefore extra large final stage larvae result, rather than alternatives dictated by normal ecdysone triggered pupation timing.
