Will pigs ever fly?
Support your answer with suitable examples. ​

Answers

Answer:

NO

Explanation:

the pigs will never be able to fly as the birds have:

wings – these enable the force of lift.

lightweight, smooth feathers – this reduces the forces of weight and drag

streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)

light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight

Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.

Answer:yes they might

Explanation:

Birds are able to breed with pigs and pigs might get wings
