Which process is affected when juvenile hormone analogue disrupts Galleria mellonella imaginal disc development?

A)Apoptosis signaling during pattern formation
B)Chitin synthesis during exoskeletal hardening
C)Hemolymph transport across epidermis
D)Mitochondrial respiration within flight muscles

💡 Explanation

When exposed to juvenile hormone analogue, imaginal discs can undergo abnormal apoptosis due to disruptions in gene expression, leading to defects preventing proper differentiation and pattern formation as concentrations normally decline for differentiation. Therefore apoptosis signalling changes, rather than chitin synthesis, hemolymph transport or mitochondrial respiration, which operate through distinct mechanisms.
