← Nature & AnimalsWhich developmental abnormality results when larval exposure to juvenile hormone analogs induces permanent activation of imaginal discs?
A)Repressed molting into pupal stage✓
B)Accelerated egg deposition in adults
C)Enhanced regenerative limb growth
D)Delayed differentiation of neurons
💡 Explanation
When larvae are exposed to juvenile hormone analogs, the perpetual presence of juvenile hormone inhibits molting into pupae because metamorphosis requires suppression of juvenile hormone enabling pupal structures from imaginal disks development . Therefore, repressed molting occurs, rather than egg acceleration, limb enhancement, or neuron delay, which involve different hormonal pathways.
