← Nature & AnimalsWhich orientation failure occurs when a migrating bird's epigenetic clock malfunctions, impairing celestial navigation?
A)Inaccurate direction calculation during flight✓
B)Failure to initiate seasonal movement
C)Improper immune system development
D)Reduced foraging success mid-migration
💡 Explanation
Malfunctioning impacts the epigenetic clock, disrupting time-compensated celestial navigation. This degrades a bird's ability to use patterns in the night sky during orientation activities, because the location calculation relies on correct timing. Therefore, direction becomes unstable rather than migrating, or foraging.
