Lizette’s teacher suggests that she use a strong solution of vinegar to kill the weeds. Vinegar is acidic and prevents plants from maintaining homeostasis. Lizette sets up a controlled experiment to test her hypothesis that the solution will kill the weeds without harming nearby vegetables. She plans to spray one group of weeds with the solution and another group of weeds with water as a control. What variables should Lizette keep the same between the control group of weeds and the sprayed weeds?

I think lizette should use the water because the vinegar would kill the weed and the vegetables because it is acidic.
