← Nature & AnimalsWhich outcome during complete insect metamorphosis affects the survival probability of the transitioning pupal stage?
A)Precise hormonal regulation imbalance✓
B)Chitin synthesis pathway alteration
C)Imaginal disc differentiation suppression
D)Enhanced nutrient storage inefficiency
💡 Explanation
When precise hormonal regulation is imbalanced during pupation, it causes developmental defects due to timing errors in gene expression within the pupa, negatively affecting imaginal disc formation and pupal survival. Therefore, hormonal imbalance becomes the main danger, rather than chitin issues, disc suppression, or inefficiencies affecting earlier larval stages, requiring a different problem profile.
