The problem is then deleted, or "dumped" to make room for the next problem. With all of these new advances, the computer was becoming easier to use. Also, with the new ferrite coils and other smaller parts, the computer was shrinking very much. Soon they would be affordable and small enough for every household to have one. This all became possible with two simple inventions: The...

Hydrogen Peroxide Degrees Celsius
539 wordsCatalase Which Is Found In The Liver' Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme, it fits into a depression on the surface of the enzyme molecule. This depression is called the active site. The reaction then takes place and the molecules of product leave the acti...
