A recent experiment was done to see whether using mascara (a cosmetic applied to the eyelashes) would increase the incidence of eye infections. A sterile swab was smeared across the eyelid and then placed in the mascara. The bacteria populations were sampled every day for one week and the following results obtained: DAY NUMBER OF BACTERIA 1 2000 2 6000 3 10000 4 32000 5 40000 6 20000 7 12000 a) Using the data from the table above, draw a graph to show the growth of the bacteria. Plot the days on the horizontal axis and the numbers on vertical axis. b) Examine your graph carefully. Generally describe the growth pattern of the bacteria. Give reasons for your answer. c) Based on the results shown, what can you conclude from this experiment? Give reasons for your answer. d) Draw and label a bacterium. e) In what ways can bacteria be helpful? Part VI: Topics.
