← Nature & AnimalsWhich risk is increased when prothoracic gland activity sharply increases?
A)Premature termination of larval feeding✓
B)Disrupted juvenile hormone production
C)Failure of pupal case hardening
D)Increased oocyte production
💡 Explanation
Premature larval molting can arise because earlier peaks in ecdysone secretion via induced prothoracic gland activity signals premature transformation; therefore larval development halts before sufficient reserves accumulate, rather than optimally transitioning to next stages when larger and primed.
