Think bаck оn the experiments yоu did in Lаb 2 regаrding bacteria and antibiоtic resistance to demonstrate natural selection. Imagine that you are doing a real experiment where you place one drop of bacteria into a circular dish containing only growth medium. You label this dish "Streptomycin Neg. -". You then create a second experimental condition by placing one drop of that same bacteria into a circular dish containing growth medium and an antibiotic called streptomysin. You label this dish "Streptomysin Pos. +". You then allow those two groups of bacteria to grow under ideal conditions for 24 hours. The next day, you look at your two dishes and you see the following results: Did the antibiotic work? In other words, is this antibiotic useful at killing these particular bacteria?
