Lupe is conducting an experiment to find out what type of antibacterial soap kills the most bacteria. in her experiment, lupe grows e. coli bacteria in ten different petri dishes. lupe then sprays 10 milliliters of an antibacterial soap on nine of the petri dishes. each of the nine petri dishes is sprayed with a different brand of soap. lupe doesn't spray any soap on the tenth petri dish. in lupe's experiment, what is the independent variable? a. the brand of antibacterial soap b. the type of bacteria grown c. the tenth petri dish

The correct answer is "The brand of antibacterial soap "

Explanation:

An independent variable in an experiment is the variable that is changed by the scientist. Independent variables are also known as manipulated variables.

In Lupe's experiment, the independent variable is the brand of soap.

In controlled scientific experiments, only one variable should be changed at a time (i.e., there should only be one independent variable per experiment). If only one variable is changed, then it is possible to clearly relate experimental results to a particular variable.
