Brown eye-color is dominant while the blue-eye color is recessive. Therefore, the homozygous for brown color is BB and the homozygous for brown color is bb. Thus, the heterozygous will be Bb (brown color). Since James has blue colored eyes a child of Jenna (brown color) and bill (blue color) then it means Jenna is heterozygous (Bb). Jenna is described as being a carrier of the allele for blue eyes.

Answer:
Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
