Problem: You would like to determine if a particular type of bacteria has developed a change in its genetic material that causes it to be resistant to certain antibiotics. You set up an experiment to test which antibiotics are effective for treating these bacteria and which antibiotics the bacteria are resistant to. You grow the bacteria and expose them to different antibiotics. At the end of your experiment, you count how many bacterial colonies there are. If the antibiotic works, there will only be a few to no bacterial colonies present. If the bacteria are resistant to that antibiotic, a lt of colonies will be present.
What would you say is the dependent variable in this scenario and how is it measured? Select one. Need Assignment Help?
