Which outcome arises when the prothoracic gland atrophies during insect metamorphosis?

💡 Explanation

Premature atrophy prevents ecdysone production, a key molting hormone; this arrests the normal progression through developmental stages because the pupal or adult stage cannot be initiated, therefore development ceases, rather than progressing or uncontrollably continuing larval stages.

• Which adaptation allows marine mammals to dive for extended periods without surfacing?
• Which outcome results from the endocrine gland failing during the larval stage?
• Which limitation impacts manta ray respiration when suspended mid-water?
• Which hormonal event disrupts pupal development when ecdysone production is prematurely terminated?
• Which outcome occurs in hot, arid climates when a C3 plant's stomata close to conserve water, impacting photosynthesis?
• Which consequence results when antivenom contains competing antibodies?
