← Nature & AnimalsWhich risk increases within a butterfly pupae upon premature ecdysone exposure?
A)Reduced complete wing vein formation✓
B)Increased melanism enzyme production rates
C)Enhanced antioxidant enzyme activity
D)Elevated metabolic conversion chitin synthase
💡 Explanation
Reduced wing vein architecture appears because the premature surge in ecdysone triggers incomplete differentiation involving apoptosis cascade of imaginal cells destined for wing vein structuring; therefore, wing veins are diminished, rather than increased pigment or metabolic processes initiated.
