Part IV: Compulsory Reply to each of the following in detail 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. degrees 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 the bacteria, Plot the temperature on the horizontal axis (x axis) and the number of colonies on the vertical axis (v 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 humanbody? Why or why not? (The normal body temperature for humans is 37 C0) d) Using a dotted line ------, extend the line of your graph to show possible results for the number of colonies at 40 degrees Celsius. Part II - Answer each of the following completely: 1. Why is the science of classification needed? 2. On what bases are living organisms classified? 3. Why is it believed that all organisms are related? 4. Describe how you can determine the magnification of a drawing? 5. Trace the history of our present day system of taxonomy. Part III - Answer each of the following with examples: 1. List the five kingdoms with two characteristics for each. 2. List the six main classes of the Subphylum Vertebrata, with two characteristics for each. 3. Describe an environmental incident that resulted in a change for the better. 4.
