Which developmental outcome occurs when ecdysone receptor genes lack expression?

💡 Explanation

Morphogenesis fails because proper ecdysone signaling initiates insect molting and metamorphosis via sequential activation and repression of target genes, therefore lacking receptors blocks adult transformation rather than altering larval molting or pupation timing.

• Which outcome follows from uneven feather wear during avian molting?
• Which thermoregulatory consequence results when soaring birds excessively gular flutter during intense sun exposure?
• Which process prevents oxygen depletion near teleost fish lamellae?
• Which biomechanical advantage results when an avian's air sacs increase lung ventilation while soaring?
• Which outcome occurs when cut herbaceous plants lack free-flowing water columns subject to tension?
• Which effect increases when shade-tolerant plants experience sudden, intense light?
