Claim: A bacterial population evolved resistance to Antibiotic Q.
A student collected these results:
1) After 20 generations with Antibiotic Q present, 92% of cells in the population can grow on plates containing Antibiotic Q.
2) A control population grown for 20 generations without Antibiotic Q has 4% of cells that can grow on plates containing Antibiotic Q.
3) Sequencing shows a resistance mutation m increased in frequency from 0.02 to 0.85 in the antibiotic-exposed population.
4) When an individual bacterial cell is exposed to Antibiotic Q, it sometimes turns on stress-response genes within minutes.
Which choice best evaluates whether the evidence supports the claim that the population evolved resistance?
