A scientist does an experiment on mice. She feeds one group of mice regular food and a second group of mice blueberries. The scientist keeps all of the other conditions exactly the same.

The mice that eat the blueberry diet do not get cancer when exposed to cancer-causing chemicals. Many of the mice that eat the regular food do get cancer when exposed to the same chemicals.

The scientist concludes that people should eat blueberries in order to avoid cancer. Is the scientist's conclusion valid?

a Yes; all scientific conclusions drawn from an experiment are valid.

b No; the study did not demonstrate that a blueberry diet can protect a mouse from cancer.

c No; the scientist did not test the effect of a blueberry diet on humans.

d Yes; the study showed that blueberries can protect animals from cancer.

The answer is C. No; the scientist did not test the effect of a blueberry diet on humans

Liana Peck · Answer 2

C, because since the blueberry has on effect on mouse, does not mean it has straight effect on human directly, they still need to test on human and record the data
