- What is the purpose of fixing a smear? Mark all that apply: 1. To attach the bacteria to the slide 2. To cause the cells to shrink and become distorted 3. To kill the bacteria so they aren't harmed by the staining method 4. To break down the cell wall in order to make the cells accept stain 5. To kill the bacteria to make the slide safer to handleWhy 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 9/14/2021What are the circles called in the staining dark
