If you completed quadrant streak plate showed two different and distinct colon appearance, what could you conclude? Select all that apply A. You initial bacterial culture inoculum contained two unique bacteria species. B. Your technique was poor, as correct quadrant streak plate protocol would have eliminated all but one species in the sample. C. Your Bunsen burner flame was too hot and caused growth of bacteria too early during the streaking. D. Your plate was inoculated with a single species, but break in aseptic technique could have allowed contaminant bacteria to also grow

What can you conclude from this streak plate? Select one: a. The plate is contaminated because only one type of bacteria should grow b. It was made from a pure culture of bacteria c. There are colonies of two different bacterial types present d. The streak plate was performed poorly because isolated colonies cannot be seen

How can you tell that the bacteria growing on a streak plate were different types of bacteria or a contaminant? Check all letters that apply. A: Different colony morphology B: You really can't tell if there are different types of bacteria or if they are the same C: Different sized colonies D: Different colors of colonies E: Different colors of agar on the plates F: The agar affects the growth of the colonies
"In the laboratory, a sterile inoculating loop is moved across the agar surface in a culture dish, thinning a sample and isolating individuals." This statement describes which of the following? a. broth culture b. pour plate c. streak plate d. dilution plate
