21)Celery stalks that are immersed in fresh water for several hours become stiff and hard. Similarstalks left in a salt solution become limp and soft. From this we can deduce that the cells of thecelery stalks are 21) A)isotonic with fresh water but hypotonic to the salt solution.B)hypotonic to both fresh water and the salt solution.C)hypertonic to both fresh water and the salt solution.D)hypotonic to fresh water but hypertonic to the salt solution.E)hypertonic to fresh water but hypotonic to the salt solution.

Refer to Figure 7.3 to answer the following questions. The solutions in the arms of a U - tube are separated at the bottom of the tube by a selectively permeable membrane membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0 sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Init volume in both arms is the same.

Write the word or phrase that best completes each statement or answers the question Read the following information and refer to Figure 7.4 to answer the following questions. Five dialysis bags, constructed from a semi - permeable membrane that is impermeable to sucrose, were filled with v concentrations of sucrose and then placed in separate beakers containing an initial concentration of 0.6 M sucrose 10 - minute intervals, the bags were massed (weighed) and the percent change in mass of each bag was graphed. Figure 7.4 27) Which line represents the bag that contained a solution isotonic to the 0.6 molar solution at the beginning of the experiment? 27) 28)Which line represents the bag with the highest initial concentration of sucrose? 28)

    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.
