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 aberrations Acid mucosubstances - correct answers a term used to include both the acid mucopolysaccharides (connective tissue mucins) and the acidic glycoproteins (epithelial mucins). Most acid mucopolysaccharides contain hyaluronic or hexuronic acid, and the glycoprotein contains sialic acid. Acid mucopolysaccharides and acidic glycoproteins do not stain the same with all mucin techniques acidophilic - correct answers a basic (cationic, positively charged) substance that is easily stainable with acid dyes. An example is cell cytoplasm, which is readily stainable with acid (anionic, negatively charged) dye eosin. Additive - correct answers a chemical or substance that adds on to, or combines with, another substance, usually improving, strengthening, or altering it. Many fixative molecules add on to tissue proteins, altering and stabilizing them in the process. Adsorption - correct answers The accumulation of stain by the surface of a tissue component. This phenomenon is influenced by the affinity of oppositely charged ions for each other (electrostatic attraction or bonding). Aldehyde - correct answers An organic compound containing carbon, oxygen, and hydrogen arranged as in the following group Alliphatic hydrocarbon - correct answers Organic chemical compound composed of carbon and hydrogen in which the carbon atoms are linked in an open chain, rather than in a ring arrangement. Aliphatic hydrocarbons can be used as clearing agents.
