See below for question. A red blood cell is placed in a beaker containing solution A for 45 minutes. The volume of the red blood cell is taken at times: 0 minutes, 15 minutes, 30 minutes, and 45 minutes. The results are: Time 0 = 350 ul Time 15 = 330 ul Time 30 = 300 ul Time 45 = 270 ul Given the changes exhibited, which of the following describes the solution in the beaker?
