Which outcome occurs when ecdysone triggers programmed cell death during fruit fly metamorphosis?

💡 Explanation

Cell apoptosis by ecdysone causes selective larval structure degeneration, due to initiating expression in imaginal discs. This targets specific cells via programmed cell death, because some larval tissues must be removed for adult formation, therefore favoring degeneration rather than preservation of existing functional anatomy.
