MCAT Question of the Day

    Q:

    		 Eosin and hematoxylin are two compounds used in staining cellular components for examination under the microscope. Eosin stains positively-charged molecules (e.g. the cytosol) and hematoxylin stains negatively-charged molecules (e.g. the nucleus). Hematoxylin provides a dark purple coloration whereas eosin provides a pinkish hue. If the cytosol of the cell drops in pH, what would we expect to occur to the coloration of the cytosol?
    		 

    A

    		 The color will remain the same

    B

    		 The cytosol will have a stronger pink stain

    C

    		 The cytosol will have a weaker pink stain

    D

    		 Not enough information provided
