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?

A.

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

B.

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

C.

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

D.

    Option A, Yes; his conclusion is supported by evidence from his experiment.

    Explanation:

    Dr. Peterson's study is supported by scientific knowledge. In his research he found that chemical A increase the growth rate of mice by 30% and in order to assure the validity of result obtained, he conducted the same experiment 4 times. And since all the time same result was obtained, the conclusions from his study can be accepted.

    Thus, any scientific knowledge which is tested and trialed and has established similar results every time can be considered a valid study.
