← Nature & AnimalsWhich immediate effect results when avian wing loading exceeds structural limits during rapid ascent?
A)Feather barbule separation increases drag✓
B)Alula feathers stall to improve lift
C)Air sac compression aids exhalation
D)Bone microfractures initiate stress remodeling
💡 Explanation
When wing loading surpasses structural limits, feather barbule interlocking, which maintains the airfoil shape, degrades because aerodynamic forces cause excessive separation, increasing profile drag and reducing lift. Therefore increased drag results, rather than stall, improved ventilation, or long-term bone modification which invoke different avian flight responses.
