You would discover that you had superhuman abilities,and that you could most likely rule the world.(you would also be extremely smart)
You would die. Without your brain your heart would forget to beat. The brain is responsible for all bodily functions. ( I know that sounds weird >.>) Oh, and there would be one happy Alien. ^^
If the brain completely stops working, the body will die, since the brain controls all the important functions for keeping the body alive. If the brain is damaged and only partially shuts down, the body enters a comatose state.
A brain bleed can have serious consequences. It is best to follow your doctor's advice. Do not take the medication until your doctor tells you that it is safe.
Well, tht would probably never happen, but if it did, you can purify salt water, its just more expensive
It depends on what organism you are talking about. Some organisms do not require a brain to "live". Organisms without a brain are usually rather simple and have a limited nimber of functions abailable to them.
All body systems are controlled by the brain.
Any human with no brain at all will not live long. The autonomic nervous system is needed to keep you alive.
unfortunately we already are using all of our "brain cells". we have no extra brain, despite the popular misconception.
Nothing would happen at all.
Nothing real - all measuring units are equally valid - BUT there would be a bit of human confusion.
all of them
This cannot possibly happen, so asking what would happen if it did happen is an exercise in stupidity.
