###### Question:

1. How does true motility differ from Brownian movement? 2. What could happen if you would touch the bottom of the motility agar with your needle during inoculation? 3 Explain why the following steps are essential during subculturing: a) Flaming the loop or needle prior to and after each inoculation. b) Cooling the loop or needle prior to obtaining the microorganism c) Holding the test tube caps in the hand as opposed placing them on the bench top. d) Flaming the neck of the tubes immediately after uncapping and before recapping. 4 How can you ascertain whether a culture grown on an agar slant is contaminated? 5 How could you explain if a four-quadrant streak plate culture shows more growth in quadrant IV than in quadrant III?
