NB :answer in at most 4 sentences.One advantage of using bacteria and viruses for genetic study is the fact that they have haploid genomes. Explain why a haploid genome facilitates genetic analysisThe graphs show a spectrum of antibiotic-resistant organisms, from 1 to 11, where 1 is the least-resistant and 11 is the most resistant. Notice that before the population replicates (graph on the left), there are no bacteria with resistance 2 or 3, OR 11. But after the population replicates, there are some bacteria with these resistance levels, indicated by the yellow arrows. Which of the following explains the origin of the bacteria pointed at by the yellow arrows? A mutations that happen when the cells in the population replicate their DNA and divide in two B some bacteria just shift one way or the other. C bacteria learn how to become more resistant
