Question

7. Which of the factor in the birds does not help them to fly-

Answer 1

Answer:

d) beaks and claws

Explanation:

Birds have many physical attributes that help them fly in the air. They include a lightweight body, streamlined boat shaped body, and wings made of feather to flap through the air.

Though birds' beaks and claws are important factors for survival and catching prey, they are not necessarily the factors which help them fly. However, beaks are considered aerodynamic and hydrodynamic because most of them are coned shaped.

So option D is the correct answer.
