← Nature & AnimalsWhich consequence results when a larval insect's steroid production is impaired during a critical instar?
A)Premature pupation without imago development
B)Adult longevity immediately and drastically increases
C)Enhanced disease resistance and growth
D)Complete stunting without pupal initiation✓
💡 Explanation
Complete stunting of growth results because the steroid hormone ecdysone triggers molting; therefore, without sufficient ecdysone production, the insect cannot progress to the next instar stage, rather than reaching a pupal stage with imaginal disc development.
