← Nature & AnimalsWhich outcome occurs when juvenile hormone (JH) concentration is moderately sustained during activation of imaginal discs?
A)Complete pupation does not occur✓
B)Larval molting cycles continue normally
C)Adult structures fully differentiate
D)Uncontrolled cell proliferation is triggered
💡 Explanation
A sustained moderate JH level allows some development; however, complete development to pupation does not occur because gene expression isn't fully switched on. This prevents the transition into the pupa stage, rather than normal molting; therefore, outcome A. Full differentiation requires lower JH.
