In one paragraph, using your own words, explain the role that natural selection plays in the growth of antibiotic-resistant strands of bacteria.
How does the increasing frequency of anabiotic resistant strains of bacteria represent an example of the occurrence of evolution? Include the three criteria for natural selection in your explanation. 
How do mutations and selection work together to create antibiotic resistance? Describe how antibiotics act as a selective pressure on a bacterial population and how mutations can lead to bacteria becoming resistant to antibiotics.

- Maria has a sore throat. Her father takes her to the doctor and she is given an antibiotic. After ten days, Maria is still sick. Use the model seen here and describe what has happened to Maria in terms of natural selection. A) The medicine causes some bacteria to become resistant to antibiotics. They survive and reproduce. B) Some of the bacteria are resistant to the antibiotic. They survive and reproduce, keeping Maria sick. C) After being subjected to the antibiotics, some bacteria change and they can survive the medicine. Maria remains sick. D) In a population of bacteria, variation exists.
