Which consequence prevents adult structures during larval development?

A)Imaginal disc growth arrest
B)Ecdysone receptor downregulation
C)Juvenile hormone excess
D)Apoptosis signaling blockade

💡 Explanation

Excess juvenile hormone maintains larval characteristics because it prevents metamorphosis via inhibiting imaginal disc maturation; therefore, adult structures can't develop, rather than the hormone cascade triggering adult transformation, prematurely halting programmed cell death, or blocking structural growth.
