← Nature & AnimalsWhich outcome diminishes gecko adhesive ability during rapid arboreal pursuit?
A)Reduced van der Waals contact area✓
B)Increased seta-substrate hydrogen bonding
C)Elevated substrate surface cohesive forces
D)Optimized capillary adhesive bridging
💡 Explanation
Reduced van der Waals contact area lowers gecko adhesion on rough surfaces during climbing because dynamic peeling reduces contact under speed, therefore grip fails incrementally, rather than maintaining adhesion which a slower rate would allow due to complete seta contact.
