3.vital cell constituents dissolved in the cellfluid pass through the cell wall causing thecells to die.4.if nothing can pass through the cell wall,the greater pressure outside than inside causesthe cell to collapse.5.more water passes in through the cell wallthan passes out so the cells swell and burst.01710.0 pointsWhich of the following molecules is most sol-uble in water?1.CCl42.benzene (C6H6)3.CH3CH2CH2CH2CH2CH34.CH3CH2OH5.CH401810.0 pointsWhich of the following has the lowest freezingpoint and the highest boiling point?1.1.0msodium chloride2.1.5mcalcium chloride3.2.0mpotassium chloride

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
