While fishing, you make the following observations: a. Water spiders appear to be able walk on the surface of the water. b. Flat rocks may be made to skip across the water. Which of the following properties of water can explain these observations? A) Water is an excellent solvent. B) Water molecules are heavy. C) Water molecules are cohesive. D) Water molecules are polar. E) Both B and C

choice C)Water molecules are cohesive

Explanation:

The observations point to the cohesive qualities and surface tension of water.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

Water is polar and a great solvent but these are not related to the observations stated in the question.

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.
