    Q:

    		 Two solutions are separated by a semipermeable membrane which freely allows water to pass through but prevents ion passage. Solution X is 30 mOsm while Solution Y is 60 mOsm. A force is applied to Solution X solution such that it exerts a hydrostatic force on the membrane separating it from Solution Y. Which of the following is true?
    		 

    A

    		 Osmotic hydrostatic forces are opposed

    B

    		 The system will equilibrate when both solutions have the same osmolarity

    C

    		 Osmotic pressure is acting to increase the volume of Solution Y

    D

    		 Osmolarity of Solution Y can be expected to increase
