Graph of Catalase

The table shows the results of an experiment done by Juan and Cindy. Juan and Cindy placed hydrogen peroxide on several food samples and recorded the relative amount of fizz that each produced. The fizz was produced by oxygen bubbles released by the action of the enzyme catalase, which is found in almost every living cell. Which of these is a valid conclusion from their data?

Farmer Brown tests the hypothesis that the more alfalfa sprouts cattle eat, the more milk they produce. He divides his pasture into four fields and puts twenty cattle in each field. Field 1 cows get no alfalfa sprouts, field 2 cows get 10 pounds of sprouts per day, field 3 cows get 20 pounds of sprouts, and field 4 cows get thirty pounds. He feeds all groups 50 pounds of regular hay per day, uses the same breed of cattle and gives them the same amount of water. He measures gallons of milk produced per cow every day. What is the independent variable in Farmer Brown’s experiment?

Question 5 options:

The amount of alfalfa sprouts the cattle are fed


The number of cattle in each field



The amount of milk the cows produce


The ratio of hay to milk produced
