← Nature & AnimalsWhich outcome occurs when flight feather barbules' structural integrity degrades, increasing wing loading unevenly?
A)Soaring efficiency decreases significantly✓
B)Enhanced high-speed flapping flight
C)Increased protection from UV radiation
D)Migration patterns remain totally unaltered
💡 Explanation
Soaring efficiency decreases substantially because the degradation disrupts the interlocking barbules, diminishing aerodynamic capability following substantial increased and uneven wing loading; therefore lift is compromised, rather than improved flight, because controlled airflow is essential to maintain lift.
