Is it true sharks have never evolved?
No, but they've remained very much the same for a very long time.

It would be possible, especially if a cow with blood on it (from a cut, for example) wandered into the ocean (or was dropped there by cruel individuals).
Why do sharks leave the meatless carcass?
Their natural diet is only interested in the fat of its prey, so a meatless carcass would be unwanted in their senses.
How does the ocean move up and down?
that depends on the type of fish. Some have swim bladders that they add or remove gas to to make them more or less buoyant respectively. Other fish such as elasmobranchs (sharks etc) have oily livers to help them float (oil floats in water) but they have to just keep swimming to stay up. Some fish live on the bottom and don't bother with any buoyancy mechanisms.
Sharks bite people because they are always in pain with their teeth growing bigger and bigger. They also feel with there mouth.
