A SimCell with a water-permeable membrane that contains 20 hemoglobin molecules and 480 water molecules is placed into an extracellular fluid that contains 20 dextrose molecules and 480 water molecules. Which of the following should happen?

1) More water molecules will flow from the SimCell into the extracellular fluid than from the extracellular fluid into the SimCell.2) More water molecules will flow from the extracellular fluid into the SimCell than from the SimCell into the extracellular fluid.3) There will be no movement of water molecules across the membrane.4) Water molecules will move back and forth equally across the membrane.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
