Figure 1
- According to Figure 1, as the concentration of Drug X increased, the percent of bacterial cells killed from Strain C:
A. increased, then remained the same.
B. decreased, then remained the same.
C. increased only.
D. decreased only.
- Based on Table 1, which strain of bacterium requires the highest concentration of Drug X to achieve a therapeutic effect for 50% of
the population that is given the medication?
F. Strain A
G. Strain B
H. Strain D
J. Strain E
- Based on Figure 1, if cells from Strain B had been treated with Drug X at a concentration of 200 mg/L, the percent of bacterial cells
killed would most likely have been:
A. less than 75%.
B. between 75% and 80%.
C. between 80% and 85%.
D. greater than 85%.
