Jeff wants to know what concentration of bleach would be most effective at killing bacteria without overdoing it and using too much bleach. Jeff makes 3 solutions of bleach in water, 1, 5, and 10% solutions. He then adds a specific number of bacteria to a test tube of each solution and waits 3 minutes. He puts these bacterial on a petri plate and later counts colonies to see how many bacteria survived. In this experiment, the
number of bacteria that were killed would be:
response/dependent variable
