H/W -. 8. The bacterium Staphylococcus aureus causes skin infections commonly called staph infections. One antibiotic that has been used to treat staph infections is methicillin. However, resistance to this antibiotic has become a widespread problem. The graph below shows the percentage of S. aureus strains that have become resistant to methicillin over a 20-years period in the United States. As you may have heard, methicillin-resistant S. aureus strains are called MRSA. Explain these data. Is evolution occurring? If so, propose a hypothesis to explain why S. aureus populations are evolution with regard to antibiotic resistance. Copyright © McGraw-HII Education.

Apply what you learned from the film: Sclentists at Work Student Vwerksheet The Great Elephant Census involved over 100 scientists working in many countries Within each country, they divided survey areas into regions, called strata, of varying shapes and sizes. Teams then flew along transect lines to estimate the number of elephants in each stratum. The lines in the diagram to the left represent the transects that a plane follows RAOHT A during an aerial survey of each stratum. The counting strips are 150-m-wide areas on either side of each transect where elephants are counted. The table below shows the data that were collected for one stratum.
