Which airflow outcome enables prolonged soaring flight because of vulture feather alignment?

💡 Explanation

Vulture wingtip feathers create slots that energize the boundary layer resulting in reduced wingtip vortices; therefore stall speed lessens, boosting soaring via lower drag, rather than parasitic drag which would hinder flight.

• Which limitation arises when elevated oxygen concentrations compete with carbon dioxide during the Calvin cycle?
• Which risk increases when reduced air sac pressure causes asynchronous breathing during thermal soaring?
• Which vulnerability occurs where a tall tree excessively exposed to wind undergoes rapid transpiration?
• Which communication enhancement occurs when plankton generate bioluminescence?
• Which outcome impairs buoyancy when gas bladder volume decreases?
