PLEASE I REALLY NEED HELP IN THIS (42 POINT'S) After conducting your experiment, answer the following questions:

What do you observe after twenty-four hours?

What two molecules (molecular species) are involved in this experiment?

In which region was the concentration of water greater—inside or outside the thistle tube—when you first set up the experiment? Explain.

Based on what you have learned about membranes and osmosis, how could you explain the results of this experiment?

1. After twenty-four hours = water level rises more on the side with sugar than on the side without

2. Sucrose (C12H22O11 ) and water (H2O)

3. The concentration of water is higher OUTSIDE the tube at the start. That side of the membrane is 100% water, while the inside of the membrane is a solution of water and sugar.

4. Water moves through the semipermeable membrane from high concentration to low concentration to reach equilibrium in a process called osmosis. The sucrose cannot pass through the membrane because the molecules are too large, but water molecules are small enough to permeate the membrane. By the end of the experiment, the water has moved through the membrane into the thistle tube so that the sugar has been diluted with more water and the concentrations are equal.
