← Nature & AnimalsWhich outcome occurs when flight feathers become detached?
A)Reduced lift and increased drag✓
B)Improved thermal regulation is gained
C)More efficient respiratory function
D)Enhanced bacterial resistance achieved
💡 Explanation
Loss of flight feathers hinders flight because the aerodynamic profile is compromised; lift decreases and drag rises due to disrupted airflow over the wing via Bernoulli's principle, therefore flight efficiency suffers, rather than other physiological changes.
