Looking at your experimental data for Beaker/Tube B. The percent concentration of both fluids is different. There is % sugar in the beaker and % sugar in the dialysis tube. Now, think of it from the water's point of view. There is % water in the beaker and % in the dialysis tube. So the beaker has a concentration of water than the dialysis tube. When you put the dialysis tube in the beaker, the water will flow across the tube's membrane and the tube.

They both determine the exact age of rocks.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
