histotechnology test 2 Question and answers already passed 2023/2024 Absorption - correct answers When tissue is penetrated by, or absorbs, a dye solution and becomes colored without any other change or chemical reaction occurring. An example is the absorption of oil red O or Sudan black B by fat Achromatic - correct answers Without color, or not easily stained. In microscopy, achromatic lenses are corrected for two colors, red and blue. This helps produce images free of chromatic aberratio...
