Unit 9: Evolution

Period: 8°
NOTES 9.9: Antibiotic Resistance
SFLT: Explain how a population of bacteria becomes resistant to antibiotics and how we can prevent it by
analyzing what it means to be "resistant".
DO NOW: Based your answers to questions 1-4 on the information below and on your knowledge of Biology.
Carlos has a real problem on his hands. He sprayed insecticide on the cockroaches outside his
door and some survived! One week later Carlos noticed that the surviving
cockroaches made
dozens of baby roaches! Kadian explained to Carlos that the surviving cockroaches were likely
resistant to the insecticide he sprayed.
1. Based upon this scenario and what we learned yesterday, define resistance in your own words.
2. Explain why the resistant cockroaches will likely outnumber the nonresistant cockroaches over time.
B. Identify the variation that exists within the cockroach population.
