Answer to Question #91502 in Physical Chemistry for nyjah saunders

Question

A scientist is testing the effectiveness of Drug X on cancer. She gives a small amount of the drug to mice that have cancer. She gives each mouse a different amount from 1 to 10 grams, and then measures the size of the tumor in each mouse before the drugs and two weeks after the drugs. She gives one of the mice sugar instead of Drug X. What is her independent variable in this experiment?

Answer 1

Solution.

To answer this problem, you need to understand what an independent and dependent variable is. An independent variable is a variable that does not change over time. That is, these are the quantities of drugs X. The dependent variable is a variable that depends on time, that is, mice that will be given medication. Therefore, the independent variable in this experiment is the amount of drug X given to mice.

Answer:

The independent variable in this experiment is the amount of drug X given to mice.
