The fоllоwing questiоn cаme from the Mаstering Biology homework. An аrtificial "cell" consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution, the "environment," as shown below. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose. Identify the correct net movement of solutes into and/or out of the cell (labeled with solid arrows) and the net osmosis (labeled with dashed arrows).(b) (c) (d) Explain why options (b), (c), and (d) are incorrect.  (Note: Please write your response for each option separately for ease of grading.  Also, you must adequately explain/defend your answer to demonstrate that you truly understand the material.)
