Dr. Peterson does an experiment to research the growth rate of mice. He has two groups of mice. He feeds one group a type of food and adds chemical A, which is supposed to increase growth rate. The other group he feeds the same food without chemical A added. His research shows that chemical A increases growth rate by 30%. He does the experiment 4 times and comes up with the same result each time.

Dr. Peterson concludes that chemical A does increase the growth rate of mice. Is Dr. Peterson's conclusion supported by scientific knowledge?

• Yes; any study that involves a percentage is based on scientific knowledge.

• Yes; his conclusion is supported by evidence from his experiment.

• No; science cannot be used to research small animals such as mice.

• No; scientific knowledge never comes from research or experiments.
