Answer 1

no i don't

Answer 2

The brain sends out electrical signals that can be measured with a special instrument. These brain signals change when a mammal or a bird falls asleep. But never change in animals such as fish or frogs--even when these animals look as if they're sleeping. Some scientists think that these animals might have a different kind of sleep. They say that their sleep can't be measured the same way yours can. Other scientists think these animals don't sleep at all but no one really knows for sure.
