Problem: If the pores in the selectively permeable membrane became larger, but still not large enough to let the sugar pass through, what would happen during osmosis in the U-shaped tube compared to what is shown in the figure? A) The final water levels would be the same as shown in the figure, but solutions would reach near equal concentrations faster.B) There would be less free water on the left side of the tube, so the water level on the right would not get as high. C) Some water would be pushed back to the left side through the larger pores, so the water level on the right would not get as high. D) More water could pass to the right side of the tube so the water would rise even higher.

If the pores in the selectively permeable membrane became larger, but still not large enough to let the sugar pass through, what would happen during osmosis in the U-shaped tube compared to what is shown in the figure? 



A) The final water levels would be the same as shown in the figure, but solutions would reach near equal concentrations faster.

B) There would be less free water on the left side of the tube, so the water level on the right would not get as high. 

C) Some water would be pushed back to the left side through the larger pores, so the water level on the right would not get as high. 

D) More water could pass to the right side of the tube so the water would rise even higher.
