A. Arg caused the P. aeruginosa bacteria to lyse under anaerobic conditions and all the polysaccharide slime coated the tube wall. B. Arg stimulated the P. aeruginosa bacteria to make much more polysaccharide slime that coated the tube wall. C. The Arg dissolved the polysaccharide into hydrophobic layers that coated the tube wall. D. The P. aeruginosa bacteria used Arg to grow anaerobically, so that it no longer had to grow at the air-liquid interface, which allowed it to form a biofilm all over the tube wall. E. The hydrophobic Arg in the medium coated the tube wall and was stained with crystal violet dye. W

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.
