By: Deepika Mukhara Experimental Design The independent variable in this experiment is temperature, concentration, and the acidity. The three levels of the independent variable are 5°C, 22°C, and 37°C. There are six trials at the 5°C and 10°C levels and 6 trials at the 22°C level are conducted. For the independent variable of concentration, the three levels are 100%, 50%, and 25%. Six trials at the 100% level, six trials at the 50% level, and six trials at the 25% level were conducted. The 100% concentration level was the control in this instance. For the independent variable of acidity, the three levels were pH

Unformatted text preview: levels of four, seven, and ten. Six trials for the level of a pH of four, 6 trials for the level of a pH of seven, and six trials for the level of the pH of ten were conducted. The level of a pH of seven is the control in this instance. The dependent variable is catalase activity. Catalase activity is measured by the rate of oxygen gas evolved in milliliters per thirty seconds. The constants in this experiment were temperature of the environment, the amount of time given for the experiment. Without these variables remaining constant, our data would not be accurate....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
