Question

PLOT DATA?

In this experiment, each student received 5 tubes of each of the following: Broth A (no sugar, no buffer), Broth B (1.0% glucose, no buffer), Broth C (1.0% glucose, buffer, and Broth D (0.1% glucose, buffer). Five organisms, which included 3 bacterial cultures, one yeast, and one mold as indicated in the table below, were used to inoculate the broths. The tubes were then incubated for 24 hours at 37°C. On day 2, the pH of each tube was approximated using a separate strip of pH paper and recoded. Data from all students was pooled and averaged. The turbidity of each of the broths was measured spectrophotometrically using a wavelength of 650 nm. Data from all students was again pooled and averaged.
