← Nature & AnimalsWhich consequence results when a larval insect lacks the enzyme ecdysone oxidase?
A)Cuticle sclerotization will prematurely occur
B)Metamorphosis cannot properly be initiated✓
C)Pupation proceeds at an accelerated rate
D)Increased cold tolerance is observed
💡 Explanation
Without ecdysone oxidase, the larval insect cannot synthesize the hormone ecdysone which triggers molting; therefore, metamorphosis is halted because prothoracic gland stimulation fails, rather than precocious hardening, fast pupation, and cold acclimatization.
