Answer:

presence of the new antibiotic.

Explanation:

According to my research on the experimental process, I can say that based on the information provided within the question in this experiment the independent variable is the presence of the new antibiotic. This can be said because the differences in results do not necessarily depend on the new antibiotic since all of the cultures are being given the same antibiotic.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
