Unformatted text preview: absorbent to light the product was. The cause of the shape of this graph could be because as we added enzymes, and we decreased the amount of water to the product, resulting in a stronger absorbency and we experimented with each trial. If we did not decrease the amount of water, we would show a much slower increase of absorbency. If we were to repeat this experiment another control could be to keep a consistent amount of water, as well as the enzymes. This way we could see a true increase in absorbency rather than a drastically altered result. However if we kept the water consistent, it would not match the consistent 5.0 ml of liquid in each test tube.
