Question

The forelimbs of birds are modified

• A. For walking
• B. For swimming
• C. For flying
• D. For grasping

Hint:

The structure of bird wings is highly specialized, including features like feathers and a lightweight skeletal system, which are all adaptations for flight.

Answer 1

The Correct Option is C

In birds, the forelimbs have undergone a significant modification to adapt to flight. The forelimbs are modified into wings, which are essential for flight. These wings are specialized for generating lift and thrust to allow birds to fly. The bones of the forelimbs are lighter and have a different structure compared to those of terrestrial animals, aiding in flight efficiency. - The forelimbs of birds are not modified for walking, swimming, or grasping (though some birds like parrots and eagles have adaptations for grasping with their feet). The primary function of bird forelimbs is flight.
