### Image: Bacteria population density as a function of time

Experimental data from measurements of bacteria population density are plotted versus time index. The data was taken from the following table with time rescaled so that each snapshot was one unit of time.

Measurements of bacterial density at pH 6.25.
The units of “Population Density” are those of absorbance as measured by a spectrophotometer.
