Which instar results if ecdysone declines before competence?

💡 Explanation

A failed larval pupal transition happens because low ecdysone prevents pupal commitment. Larval-larval molting continues rather than ceasing, therefore, resulting in delayed molting into more larval stages, instead accelerating metamorphosis into a pupa stage.

• Which outcome results from ecdysone deficiency during larva's final molt?
• Which risk is amplified when some desert plants experience extended drought conditions?
• Which outcome occurs when a raptor experiences localized feather structural failure during a dive?
• Among honeybees, which effect dominates when ambient light obscures portions of the waggle dance observation?
• Which developmental outcome results when an insect's imaginal discs fail to receive sufficient ecdysone during molting?
• Which risk increases when a bony fish migrates rapidly between fresh, saltwater regions?
