(L2) Which one of the following is the best definition of osmosis? A. The movement of water from a solution with a
high concentration of water to a
solution with a low concentration of water across a semi-permeable membrane.
B. The movement of a dissolved substance from a concentrated solution to a less
concentrated solution across a semi-permeable membrane.
C. The movement of water from a solution with a low concentration of water to a
solution with a high concentration of water across a semi-permeable membrane.
D. The uptake of water by a living cell.

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.  

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
