What was the researchers' main hypothesis? What was the researchers' main hypothesis? Predation results in selection for smaller guppies. Predation results in selection for brighter color patterns in guppies. Predation results in selection for more drab color patterns in guppies. Predation results in female guppies preferring to mate with more brightly colored males.

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.  

well the answer is 2!
