← Nature & AnimalsWhich outcome results when iron-containing organelles degrade in migratory birds?
A)Diminished magnetic field sensitivity✓
B)Increased susceptibility to viral infection
C)Reduced plumage coloration intensity
D)Impaired muscle energy production
💡 Explanation
Iron-containing organelles facilitate magnetoception via the radical-pair mechanism, sensing Earth's magnetic field during migration; therefore, their degradation impairs navigation, rather than enhancing disease vulnerability or pigmentation, because it interrupts magnetic sensing pathways.
