A microbiologist has isolated a new strain of bacteria, and is trying to characterize aspects of its growth. Three flasks of the same media have different amounts of NaCl added. Other growth conditions are identical, and the flasks inoculated at the same time. At regular intervals over a 3 hour period, culture samples are taken and turbidity is measured. Here are the absorbance values over time in a table and graphed.
