Questão 2
Questão
How would you describe the similarities between a bird and a plane? Or, what is the major similarity that the two have? Please give a detailed answer...=D
Questão 3
Questão
What is the greatest difference between a plane and a bird?
Responda
-
One is an animal and one is a machine
-
One is bigger than the other
-
Birds have feathers, and planes don't

Questão 4
Questão
How are helicopters aerodynamic?
Responda
-

-
The shape of the body is aerodynamic, and the blades slice through the air, and how the air hits the airfoil
-
The way the air hits the airfoil
Questão 5
Questão
Birds have microscopic magnets in their beaks, which allows them to know where they are going while flying. So, it's like birds that migrate have a little compass on/in their beaks. True or false?
Questão 6
Questão
A bird needs feathers to fly because the feathers provide a strong enough surface to catch the wind. Birds also need feathers to keep themselves warm, and protect them from the rain.
