← Nature & AnimalsWhich process impedes complete wing development of a holometabolous insect if imaginal disc ecdysteroid conversion is blocked?
A)Apoptosis inhibition in larval tissues
B)Cellular differentiation is prematurely activated
C)Chitin synthesis in exocuticle malfunction
D)Pupal-adult epidermal transition stalling✓
💡 Explanation
When ecdysteroid conversion is blocked, the hormone cannot properly trigger the pupal-adult metamorphosis because epidermal transitions rely on its signaling, which affects the imaginal discs leading to incomplete wing formation. Therefore, epidermal transition stalls rather than other processes related to larval apoptosis, uncontrolled differentiation, or disruptions in basic skeletal structure synthesis.
