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

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

How can you tell that the bacteria growing on a pour plate were different types of bacteria or a contaminant? Check all 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 colors of colonies D: different colors of agar on the plates E: the agar affects the growth of the colonies since they are embedded in the agar F: different sized colonies

You counted different different types of bacteria on the plates. How can you tell that the bacteria were different types of bacteria? Check all 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: there was only on type of bacteria on the plates D: different sized colonies E: different colors of agar on the plates F: different colors of colonies
