You have discovered a gene that enables organisms to accumulate gold in their tissues by concentrating trace amounts found in normal soil. you want to transfer this gene into a plant. order the steps below that would accomplish this. infect the plant with the agrobacterium strain. digest the gold gene and a ti plasmid with appropriate restriction enzymes. insert the gold gene into the ti plasmid. amplify the gold gene with pcr. transfer the recombinant ti plasmid into agrobacterium tumefaciens. use a selectable marker to identify plant cells that have integrated the recombinant plasmid into their genome. a. 4 2 3 5 1 6 b. 4 5 2 3 1 6 c. 4 2 5 1 6 3 d. 4 3 2 5 1 6

answer; i believe that the correct answer is (light);

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.  

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
