← Nature & AnimalsWhich consequence occurs when the prothoracic gland atrophies prematurely in a beetle larva?
A)Adult structures develop in larval stage
B)Ecdysone production diminishes spuriously
C)Larval molting stages arrests abruptly✓
D)Imaginal disc differentiation is prematurely initiated
💡 Explanation
Premature gland atrophy prevents ecdysone release; thus, larval molting arrests because the hormonal trigger is absent. Without sustained ecdysone, the larva cannot attain pupation, therefore correct rather than prematurely metamorphosizing or wrongly differentitiating, needing ecdysone.
