During an Ames test, an experimental sample of His- bacteria was exposed to a potential mutagen. As a control, another sample of the same His- bacteria was not exposed to the mutagen. A total of 10 million bacteria from each sample were then plated on different plates containing media that did not contain histidine. The results were as follows: Control plate (not exposed to potential mutagen): 12 colonies Experimental plate (exposed to potential mutagen): 1097 colonies   Do the results indicate that the potential mutagen was mutagenic?
