- Fill in the blank: The gram stain is a ______________ stain in which a decolorization step occurs between the application of two basic stains.The following figures are the photomicrographs of the samples taken with Kern&Sohn Camera Microscope at 10x magnification. Samples were stained with Lugols solution for better viewing. Differentiate these two imageGram staining techniques
- Which one of these techniques does not distinguish between live and dead cells? Group of answer choices Coulter count fluorescence staining spread plateIf a spectrophotometer is available, dispense the culture into labeled corvette and determine the optical density of each cultureFluorescent stains can be viewed on ____________ microscopes.
- True or False: The coarse and fine adjustments are partof the microscope’s mechanical system_________________.Please write, in paragraph form, how you would identify the organism step by step. Remember to provide as much detail as possible, including but not limited to staining procedures, identification methods and their results. You have been given the final answer (type of organism), now explain to me in detail how you would come to this conclusion Type of organism Topic is : Proteus vulgarisTrue or False: The microscope should be stored with the oil immersion lens in position over the stage. If this statement is false, correct the statement.
