← Nature & AnimalsWhich outcome increases when juvenile hormone concentration falters prematurely during a larval stage's ecdysis?
A)Accelerated pupation occurs prematurely✓
B)Organogenesis within the pupal stage delays
C)Enhanced expression of chitin synthesis
D)Reduced immune cell differentiation occurs
💡 Explanation
Prematurely lowered juvenile hormone causes inappropriate activation of the pupal developmental program because of reduced inhibition of the Broad-Complex gene; therefore, direct transition to pupation will occur, rather than further larval growth because imaginal discs are no longer suppressed.
