The final paragraph of the cnn report said that "several eye specialists" had pointed out that the study should have accounted for heredity. myopia is passed down from parents to children. it's also reasonable to suppose that myopic parents are more likely to leave lights on in their children's rooms than other parents. in what way does the knowledge of this possible genetic link affect how we consider the data? write your answer here, replacing this text.

weathering is the answer.

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.
