1. Briefly define the concept of \"aseptic and sterile technique\". 2. When streaking for isolation using the \"quadrant streak\" method, why is sterilizing the inoculating loop or using a new loop in between each streak important? 3. If a kitchen countertop looks clean, is it void of microorganisms? Why or why not? 4. Observe the streaked plate below. How would you improve the streaking method shown in Plate 1 in order to get a better isolation of single colonies? Draw or describe your improved streaking pattern on Plate 2.
