Asked by Jenny
You are testing the injection of a new chemical on mice to see if it can shrink tumors. To properly administer the chemical, it must be dissolved in water with ascorbic acid (vitamin C) and injected into the middle of a tumor. As a positive control, you plan to similarly prepare and inject a chemical that is already known to shrink tumors. What is the best choice for a negative control treatment?
Would it be injection of water and ascorbic acid? A negative control is when you want nothing to happen right? Or would it be injection of nothing?
