The experimental setup consists of two (2) culture plates, each containing a different type of bacteria, either Bifidobacterium. longum or Bifidobacterium. pseudolongum. After a period of growth, the number of cells of each type are recorded as Log10 Cell Count per mL culture. The researcher then adds a set amount of the antibiotic ampicillin to each plate and measures the number of cells in each plate at various time points. Table 1 represents the data recorded for this experiment. a. Identify the dependent and independent variables
