    Biology investigation: Liver and hydrogen peroxide By Cuong Tran Abstract: The purpose of this investigation was to determine the optimum temperature for enzyme activity. The stated hypothesis was that 37oC would be the optimum temperature for liver enzymes to break down hydrogen peroxide into water and oxygen. The dependent variable was to measure the amount of foam being produced‚ while testing 4 different temperatures with 3 repetitions each. Out of the 12 trials only 2 outliers were found

    relation to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United
