refer to the graph above. scientists conducted an experiment to test how resistant a bacteria species is to five different substances. which substance is this species of bacteria most resistant to?
○ carbapenems
○ cephalosporins
○ aminoglycosides
○ fluoroquinolones
○ polymyxins

Explanation:

To determine the most resistant substance, we analyze the graph's y - axis (resistance percentage) and the lines for each substance. The line for Fluoroquinolones (red) reaches the highest percentage of resistance across the years (around 25 - 30% at 2012), which is higher than the other substances' resistance levels.

Answer:

D. Fluoroquinolones
