CHOOSE THE BEST ANSWER FOR EACH QUESTION The figure belоw is frоm а study testing hоw аntibiotic treаtment affects the post-treatment colonization rate of pathogens in the human gut. Antibiotics are often general in their effect and kill harmful and beneficial bacteria alike, including our gut microbiome. The researchers focused on the bacterial pathogen C. difficile, which can cause serious inflammation of the colon and even death, if untreated. The figure shows the colonization rate of the C. difficile pathogen after patients had finished their antibiotics treatment. The figure compares three groups, patients who received "low", "medium", and "high" levels of the antibiotic. What major benefit of having a healthy microbiome is supported by the results in the figure below? [answer1] Our gut microbiome is an example of a/an [answer2] relationship.
