Question

Choose the correct answers from the alternatives given.
Which of the following characteristics is not associated with flight requirements in birds?

• A. Feet with claws
• B. Light hollow bones
• C. A light horny beak with no teeth
• D. An enlarged breastbone with strong muscles attached

Answer 1

The correct option is A Feet with claws

1. The bodies of birds are adapted for flying. Many of a bird's bones are hollow which makes birds' bodies lightweight.
2. Flying birds have large chest muscles that move the wings. Birds have feathers that help them fly.
   
3. And instead of weighty jawbones and teeth, birds evolved a light and serviceable beak made of keratin. Most birds consume energy-packed foods rich in calories – like seeds, fruits, and meat, which add as little as possible to a bird’s payload.
   

So the correct answer is "feet with claws".
