← Nature & AnimalsWhich process causes developmental arrest during the diapause stage of insect metamorphosis?
A)Mitochondrial uncoupling triggering apoptosis
B)Hormone signaling pathway downregulation✓
C)Lysosomal enzyme degradation cascade
D)Ribosomal RNA transcription termination
💡 Explanation
During diapause stage, reduced temperatures cause epigenetic modification, suppressing key hormone signaling pathways such as ecdysone and juvenile hormone, arresting development. Therefore hormonal downregulation results, instead of apoptosis, lysosomal degradation, or transcription termination, which involve different cellular mechanisms of developmental change.
