What hypothesis were the researchers testing in this study?

Sugar beet seedlings have a higher rate of fungal infection in heated soils.

Soils can be treated to reduce their ability to suppress fungal disease in seedlings.

The disease-suppressive properties of soils are due to the activities of soil microorganisms.

Sugar beet seedlings have a lower rate of fungal infection in disease-suppressive soils.

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.  

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
