Unformatted text preview: do not swell or shrink the cell. (Bio 05LA Lab Manual-Lab#6, UCR, Winter ’08 ed., pp2 parag#1). 5. In optical density, the amount of light scattered is proportional to the number of particles in suspension. (Bio 05LA Lab Manual-Lab#3, UCR, Winter ’08 ed., pp3 parag#1). Experimental Strategy: The spectrophotometer will be used to keep track of the presence of intact RBC’s. The number of cells will affect the optical density. The cells that are not osmostically lysed in a certain solution are capable of scattering visible light and therefore that solution will have a high optical density. Prediction: If the isotonic concentrations for RBC’s will decrease with exposure to different solutions of increasing osmolarity but equal concentration, then the molarity of the ionic compounds will be less than the molarity of glucose....
