These precautions are very important to have a successful crime scene investigation (A Guide for Investigating Bomb and Explosion Scenes: Evaluating the Scene‚ 2001). To decrease the risk of contamination the scene must be investigated as soon as possible. Fire accelerants and explosive powders can evaporate within hours or days

Similarly‚ the “old” musics should not be approached with the attitude of preserving or mimicking other people’s

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate
