Value 7 points Part VI: Graphing. Plot the following data and answer these questions. 1. The data table below shows the results obtained from an experiment carried out to determine the best temperature for growing bacteria. The culture medium was prepared and then inoculated using the streak method. Samples for streaking were obtained by rubbing Q-tips along the chalk ledge. After inoculation, each petri dish was placed in an incubator that could control the temperature at the required settings. After 72 hours, the bacteria colonies were counted and the results recorded. DATA TABLE: Temperature (Celsius) Number of colonies 5 10 10 22 15 100 20 150 25 200 30 80 a) Using the data provided, draw a graph to show the effects of temperature on the growth of bacteria. Plot the temperature on the horizontal axis (x axis) and the number of colonies on the vertical axis (y axis). b) Examine your completed graph carefully, what can you conclude? c) Based on the results obtained, do you feel that these bacteria could possibly infect the human body? Why or why not? (The normal body temperature for humans is37C0) d) Using a dotted line... extend the line of your graph to show possible results for the number of colonies at 40 C0. d) Examine your graph carefully. Generally describe the growth pattern of the bacteria. Give reasons for your answer. f) Based on the results shown, what can you conclude from this experiment? Give reasons for your answer. Value 10 points Part VII: Reading. Read the following article and answer the questions. 1. What new problems might result from using bacteria to fight pollution? 2. How were the numbers of bacteria increased for use by scientists? 3. Why are bacteria such good cleaning agents? 4. What is the most common method of bioremediation? 5.
