Ascientist wants to determine whether a new chemical she isolated can cure a certain disease. to test her hypothesis that the new chemical cures the disease more effectively than current treatments, she infects mice with the disease and gives them the new chemical. she then assesses how many mice were cured of the disease. what is missing from her experimental design?

       What is missing from her experimental design is a control group.

Explanation:

       Every scientific design nowadays need a control group. This control group will serve as a comparison to her after she treats the other group with her hypothesis. In this case, the control group needs to be related to her hypothesis, so it would be a control group treated with the old chemical treatment. With this, after she treats the mouse she can do the comparison and the math needed to finish her research.

that is true   : ) hope this you
