a) 5.5% glucose and 0.9% NaCl have the same osmolarity. What is the osmolarity of these solutions? Please show your work. b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.

Draw a beaker that is filled with water. Label the water with an osmolarity of 0.61M. In the water, draw a single Elodea cell (note: Elodea is an aquatic plant) with a cellular osmolarity of 0.42M. Name this drawing with the tonicity term that best describes the solution of the water in the beaker compared to the osmolarity of the Elodea cell. Then describe what will happen to the tonicity of the cell over time. Make sure to explain the direction that water will flow, small molecules will diffuse, and explain what will happen to this cell over time. Make sure you use all of the applicable tonicity terms in your description.
