- Different stains have different affinities for different organisms or different parts of organisms. Elaborate on this statement using the Hematoxylin and Eosin staining as an example.The benefits of the negative stain include: Mark all that apply: O No shrinkage or distortion of cells due to no heat or methanol fixing Because the cells don't take up stain they don't get shrunk or distorted O One can more accurately determine cell size and shape because the cells stand out against the background One can more accurately determine the cell size and shape because there is no shrinkage or distortion of cells O Negatively charged dyes are safer to work with than positively charged dyes IMicrosoft B 11:32 AIn order to do electron microscopy the samples had to be specially prepared. Were the cells alive at the time of viewing?
