Answer 1

C. they are lighter, which helps with flight

Step-by-step explanation:

Have a great day

Answer 2

C. But see the answer under C. Apparently C is the accepted answer.

Step-by-step explanation:

A. Not A.I don't think that's a problem for gulls especially on beaches.

B. Not B. Their feather do not look like they need much help in keeping their feathers attached when in flight.

C. This is not really the answer, but it is the best answer of these 4. The actual answer is that the bones are porous for better air intake which provides more oxygen and hence they are better able to fly.

D. Not D. Food has nothing to do with the problem. Birds get an adequate amount of food without their wings being porous. See the answer for C.
