Question

scientists are studying the effectiveness of an antibiotic. they have a mixed population of 33% resistant and 67% nonresistant bacteria. they add an antibiotic to the bacterial environment and allow the bacteria to grow. what percent of the population would be expected to be resistant to the antibiotic at the end of the experiment? enter the answer in the box. the number of resistant bacteria will change to %.

Explanation:

Step1: Analyze the situation

The non - resistant bacteria will likely be killed by the antibiotic, while the resistant bacteria will survive.

Step2: Determine the final percentage

Since only the resistant bacteria will remain after the antibiotic takes effect, the percentage of resistant bacteria in the population at the end of the experiment will be 100%.

Answer:

100
