Directions : Select the correct location on the diagram. Some skateboarders use a structure called a half-pipe, like the one shown below, to perform impressive tricks.

Cody is about to drop into the half-pipe on his skateboard. Four positions in the half-pipe are marked with blue circles. At which position will Cody's kinetic energy be the greatest?

can you give me more to work here with plzs and you

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.  

the answer is b.) hydrogen bonds between bases.
