What role does selection pressure (presence of antibiotics) have in antibiotic resistance? A) The presence of the antibiotics maintains the change in the genome that allows for resistance in the population B) The presence of the antibiotic allows more bacteria to be present, creating an ideal environment for gene exchange C) The presence of the antibiotic has no role in resistance D) The presence of the antibiotics causes the mutation

Why are bacteria often transformed with an antibiotic resistance gene? Group of answer choices The antibiotic will not kill the bacteria without the gene The gene causes the bacteria to resistant to all antibiotics The gene can be used as a selectable marker when culturing bacteria All plasmids must have an antibiotic resistance gene for the transformation to be successful.

Look at the image above. The red bacteria contain one or more genes that express resistance to antibiotics, while the yellow bacteria do not have this variation. Describe how the changes in trait distribution within this bacterial population are affected by the presence of antibiotics and the environment. Describe the relationship between antibiotic resistance and natural selection.

What are the two mechanisms through which bacteria acquire antibiotic resistance (two points)? Modify or bypass the target of the antibiotic and stop the antibiotic from reaching its target. What is the selective pressure in our environment that causes bacteria to become resistant to antibiotics (one point)? More than half of antibiotics sold in America go to production (one point). When we test for antibiotic production from bacteria, we look for killing of safe relative bacteria by looking for a (two points). When we test for antibiotic resistance of bacteria, we look for of bacteria on food containing the antibiotic (two points). Why do we store/preserve bacteria in glycerol solution (one point)? At what temperature do we store our glycerol stocks (one point)?
