Jonathan is learning about water conservation. he learns that the average household in the united states uses 293 gallons of water per day. jonathan makes a chart that shows the percent of water that each indoor fixture uses in the average u. s. household. he would like to use this chart to determine which indoor fixture uses the most water in his own home. then, he can replace this fixture with a more efficient, water-saving fixture. what would be an appropriate research question to guide jonathan's research project? a) how can we use less water at home? b) how can the united states conserve water? c) which fixture uses the most water in our home? eliminate d) do shower heads use more water than sink faucets?

Option C, Which fixture uses the most water in our home? Eliminate

Explanation:

The overall agenda of Jonathan's experiment is to conduct an experiment through which he will try to identify the fixture which causing the maximum water loss and then this fixture will be replaced with an efficient fixture to reduce water wastage.

Thus, once the agenda is clear, the most appropriate question among the given options would be option (C) Which fixture uses the most water in our home? Eliminate

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.
