Walking down a dark New York street late at night you suddenly feel the metal barrel of a pistol press against your head behind your ear and hear the instructions "Don’t move a muscle while I slip your wallet out of your pocket." Unfortunately, you do move, the gun is fired, and the bullet enters the brain. Breathing and heart beat stop almost immediately. Where is the bullet?

in the Brain Stem

Explanation:

When the gun has fired the casing of the bullet would have been expelled from the gun and most likely landed on the floor, while the projectile in this scenario would have entered the victim's brain and destroyed the brain stem. Most likely stopping in the brainstem or nearby it. This is the most likely scenario because the brainstem is what completely controls the bodies breathing, heart rate, and other important functions of the body by giving it instructions. Damage to the brain stem would cause breathing and heartbeat to stop immediately as all communication would come to a complete stop between the brain these organs.

answer: the answer is d.

explanation: this is because when you exercise you make your muscle produce a certain liquid, that does not evaporate it.   also when you exercise you do not reduce muscle fiber.   and it does not really control your twitch that much.
