← Nature & AnimalsWhich functional outcome emerges when certain signals disrupt imaginal disc eversion during metamorphosis?
A)Antennal duplication develops improperly over the thorax✓
B)Ecdysis is expedited before the critical period
C)Larval molting accelerates within several hours
D)Juvenile characteristics are retained due increased feeding
💡 Explanation
Antennal structures duplicate abnormally because localized disruption of morphogen gradients causes improper activation, violating positional information. This antennal development occurs ectopically on the thorax therefore, rather than normal differentiation, because discs lose spatial context under disruptive signaling.
