What are some ways that mammals differ from birds?
To start off, birds flap their wings to propel themselves forward whereas airplanes propel themselves forward using a propeller that spins around. Airplanes use wires (both electrical and cables) to maneuver. Birds twist their wings to maneuver. Airplanes also have lights to show their orientation and location. Birds on the other hand have no lights because they really don't need them! Airplanes are made out of metal which doesn't repair itself it it gets broken or injured like a bird does. Airplanes need aviation fuel to run where birds just get their energy from seeds, bugs..etc. hope that helped
Difference and similarities of birds reptils and mammals?
SIMILARITIES. Birds, reptiles, and mammals are all a part of the animal kingdom! (OH MY GOSH!) They all need the same things- food, water, vitamins, nutrients, and things of the such. They are all multi-cellular, eukaryotic organisms. They all have the ability to mate and raise/have offspring. These three also all have similar body parts, and body functions. DIFFERENCES. Mammals give birth to live offspring- birds and some reptiles don't and lay eggs. Birds have the ability of flight- mammals and most reptiles do not. Reptiles are covered in scales or some other form of rough 'coat'- birds have feathers (though some like the Cassowary have some rough and slightly scaly napes and such), and mammals have fur and things of the such. Reptiles and most birds are warm blooded- mammals are cold blooded. Hope it helped! :D ~AP Wulf
