- Which of the following statements is FALSE? Question options: stains increase the contrast of a specimen with its surroundings all of these statements are TRUE dyes generally consist of a chromophore and an ion the chromophore of an acidic dye is positively-charged simple staining procedures use a single dye basic dyes bind to negatively-charged moleculesIs is best to observe slides of bacteria stained with the acid fast stain under high dry magnification. True or falseWhy is it important to limit the quantity of cells used to prepare a smear? Mark all that apply: O So that cells are not clumped and don't entrap stain creating erroneus results So that no contaminants are introduced onto the slide by being entrapped in clumps OSo that the cells are spread out enough that cell morphology can be discerned OSo that the cells are spread out enough that the arrangement can be observed O So that there are small groups of cells clumped together to make them visible Microsoft Bing 11:31 AM 87°F Sunny 9/14/2021
- A capsule stain is kind of: A Simple and Negative Stain B Differential and negative stain C Simple Stain D Differential stain E Negative StainChoose the 4 most correct steps from the list below for a simple positive stain and organize them into the most correct order. Briefly explain the purpose of each step you chose. • Heat fix • Dip slide in acid alcohol • Wash slide with ethanol • Apply Congo Red to the slide • Apply Crystal Violet to the slide • Make a smear • Wash slide with waterIf you Gram stain a bacterium that is gram-negative, which dye will be visible once the stain is completed? Crystal violet Safranin Decolorizer lodine
- What is the purpose of a bacterial smear? What is the purpose of a bacterial smear? It spreads the bacteria out into a single layer. It kills the bacteria. It helps the bacteria stick to the slide so they do not wash off during staining. All of the above. None of the above.Draw what you would expect to see for acid fast stain and endospore stain procedure if you did not stain with counterstain. Color pencils need to be used.Is acid fast staining differential stain , if yes, what are the 2 types of stain used
- This part of the staining process helps the primary stain to remain in the cell during decolorization. O 1) Secondary stain O 2) primary stain O 3) counterstain O 4) fixing reagent O 5) mordantYou receive a bacterial culture in the lab and your job is to figure out information which will be helpful. You are only allowed to use one of the staining methods we practiced. Which one would be the best option? Why? And what will this information help you determine? Explain.Which of the following serves as a counterstain for the gram-stain technique? It also happens to be the counterstain for the endospore staining technique.
