During silk moth metamorphosis, which consequence occurs relating to the larval epidermis during the pupal quiescent stage?

A)Apoptosis eliminates larval-specific cells
B)Cell division creates adult structures
C)Chitin synthesis halts permanently
D)Prothoracicotropic hormone dominates permanently

💡 Explanation

Apoptosis removes larval epidermal cells because of hormonal signals that activate programmed cell death—a crucial part of metamorphosis—therefore only imaginal discs’ cells differentiate, rather than reverting larval cells or halting chitin production.
