Biology students use raw eggs an experiment on tonicity and osmosis. students put their eggs into vinegar to remove the shelves.
8_murik_8 [283]

The vinegar removed only the shell of the egg because it was acidic. But it was unable to mess with the egg, because as it removed the shell of the egg, it was unable to get past the sac, the part that protects the inner egg. It is hard to puncture this sac, unless dropped or punctured by a nail or something hard.

They can be very dangerous and usually require medical care right away. Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Ventricular tachycardia is an abnormal electrical impulses that start in the ventricles and cause an abnormally fast heartbeat. This often happens if the heart has a scar from a previous heart attack. Usually, the ventricle will contract more than 200 times a minute. Ventricular fibrillation is an irregular heart rhythm consisting of very rapid, uncoordinated fluttering contractions of the ventricles.The ventricles do not pump blood properly, they simply quiver. Ventricular fibrillation is life threatening and usually associated with heart disease. It is often triggered by a heart attack.</span>
