Question Description
Directions:Read the passage and choose the best answer to each question.PassageA scientist tested the ability of 5 newly engineered drugs to kill penicillin-resistant bacteria.Experiment 1Equal numbers of penicillin-resistant bacteria were put into flasks containing 10.0 milliliters of a nutrient medium.The flasks were incubated for 1 hour at 37 C with different concentrations of the 5 drugs shown in Table 1. A control consisted of bacteria incubated in the medium without any drugs. The bacteria were washed to remove residual drug traces and grown on nutrient agar plates for 7 days. During this time, the bacteria reproduced, forming colonies, which were then counted at the end of the seventh day. Plates with more colonies were assumed to have more live bacteria at the end of the 1-hour incubation period. Table 1 shows the number of colonies counted. The drug-free control showed 50 colonies at the end of 7 days.Experiment 2Bacteria were handled as described in Experiment 1 with two exceptions: all drugs were tested at the same concentration and the incubation time of each culture was varied. Table 2 shows the number of colonies counted for Experiment 2.Experiment 3Permeability coefficients measure a drug’s ability to break through the cell membrane of a bacterium. The larger the permeability coefficient, the faster the drug is able to transfer through the membrane. The molecular mass, in atomic mass units (amu), and permeability coefficient, in centimeters per second (cm/s) of the 5 drugs at 37 C were measured. The results are shown in Table 3.Q.Which of the following statements best describes the relationship between the molecular mass and the permeability coefficient of the drugs, as shown in Experiment 3?a)As the molecular mass decreases, the permeability coefficient increases.b)As the molecular mass increases, the permeability coefficient increases.c)As the molecular mass decreases, the permeability coefficient remains constant.d)As the molecular mass increases, the permeability coefficient remains constant.Correct answer is option 'A'.
