ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

Cause/Effect of health issue such as heart disease The easiest way to define cause and effect is “one thing leads to another”. The one thing is the cause that leads to (or results in) “another”‚ the effect.
