← Nature & AnimalsWhich process occurs when the prothoracic gland atrophies during metamorphosis?
A)Larval molting cycle continuation
B)Imaginal disc cell proliferation arrests
C)Ecdysone production ceases entirely✓
D)Juvenile hormone synthesis intensifies again
💡 Explanation
Cessation of ecdysone production occurs, because atrophy leads to functional gene inactivation, suppressing ecdysone synthesis within the prothoracic gland; therefore further development proceeds into the pupal stage, rather than triggering another larval molt driven by ecdysone.
