Which outcome results when ecdysone signaling is disrupted specifically within imaginal discs of a caterpillar?

💡 Explanation

When ecdysone signaling is disrupted, specifically in imaginal discs, cell differentiation to form adult structures is inhibited because ecdysone triggers expression of genes required for metamorphosis outcome. Therefore, failure of adult structures results, rather than other effects, which rely on hormone signalling outside imaginal discs.
