Question

The students conducted a second experiment, using raw chicken liver as they did in the previous experiment. They modified the chicken liver and used: one whole piece, one piece cut into two, a piece that they pulverized in a blender. All the livers were the same mass. The liver was placed in test tubes and hydrogen peroxide was then added to each. Here are their results: Chicken Liver and Enzyme Action Liver Condition Rate of fizzing whole 9 two pieces 11 pulverized 14 In the second experiment, how does the students' design mimic the digestive process? A) There is little difference between the various states of the chicken liver and the rate of digestion. B) The blending or pulverization represents mechanical digestion and the enzyme activity represents chemical digestion. C) In the second experiment, the students represent chemical digestion by adding the hydrogen peroxide to the chicken liver. D) Changing the condition of the liver represents mechanical digestion; adding the hydrogen peroxide represents chemical digestion.
