What do the results tell us about the experiment? The bacteria from all 3 farms were almost 100% alive in the control samples, meaning that the experiment did not work. None of the bacteria from the 3 farms survived in the control samples. Because the bacteria in the control were almost 100% alive, we know that any deaths of bacteria in the other samples was because of the antibiotics.

Antibiotic is effective in controlling of bacterial growth.

Explanation:

The results tell us a lot of information about the experiment because in the experiment, different samples of bacteria were taken and check the effect of antibiotics on them. From the result we know that bacteria survive in all that samples which was not treated with antibiotics while those samples which was treated with antibiotics, bacteria was not survive so we conclude from this results that antibiotic is effective in controlling of bacterial growth.
