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. :)
The answer is d. semi permeable nature of the membrane
For Plato it think its c-Flowers of corn are pollinated by the wind. They are small and lightweight to allow easy pollination by the wind.<span> They do not need to attract animals or insects and are therefore colorless and odorless.</span>
The most plausible evidence that birds have evolved from dinosaurs is that the birds have the exact same bone structure as one of the dinosaur super-families, the <em>Saurischia. </em>In this group of dinosaurs we have the total same skeletal structure as in the birds, and most of the dinosaurs of this branch were bipedal, as are the birds, both flying and nonflying.
Enzymes serve to speed up reactions by lowering the energy of activation, the amount of energy needed to begin a reaction.
