← Nature & AnimalsWhich developmental outcome prevents complete metamorphosis if juvenile hormone concentration remains high during larval molts?
A)Prolonged feeding and growth phase✓
B)Premature pupation and dwarfing
C)Immediate reproduction bypassing adulthood
D)Arrested development and death
💡 Explanation
When high juvenile hormone concentration persists, continued larval molts occur because imaginal discs, which form adult structures, are repressed by juvenile hormone, preventing pupation. Therefore prolonged larval stage results, rather than early pupation, immediate reproduction, or death, which require low or absent juvenile hormone.
