PLEASE HELP! I NEED THIS DONE SOON! ALL MY POINTS!! I'LL GIVE FIVE STARS AND A BRAINLIEST PLEASE! HELP ME
An experiment is designed to compare the effects of glucose and sucrose on the osmotic potential of a model cell. Two dialysis bags are used, one filled with a solution of 5% by mass glucose and the other with a 5% by mass sucrose solution. A given membrane is permeable to water but impermeable to glucose and sucrose. Each membrane bag is then placed in a beaker of distilled water for two hours. The change in mass of the glucose nag is recorded below:
a. Describe the process of diffusion through the dialysis bags. (Note: Sucrose does not travel).
b. If you were to design a different experiment testing rates of diffusion, identify experimental procedures.
c. Analyze that data in the chart and describe the results. Predict the change in mass of the sucrose membrane bag, compared to that of the glucose membrane bag. The molar mass of glucose is 180 g/mole, and the molar mass of sucrose is 342 g/mole. (Note: You do not need to calculate final mass).
d. Based on the results, explain the increase in mass of the glucose membrane bag in terms of the movement of particles through the membrane. Provide reasoning that describes how this relates to osmotic pressure.

The prone position provides extension of the hip and knee joints. In assuming the prone position, the patient is placed on their stomach, while they face to the side. The patient is placed with the back of their hands on the bed. The prone position is opposite to the supine position.
