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. :)

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.

hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

$CO_{2}$ undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

Design a laboratory-based experiment to test the hypothesis that algae need light to grow.

Shalnov [3]

The same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

<h3>What is algae growth?</h3>

The growth of algae is the process by which the organism increases in size. Now we know that that the algae is photosynthetic hence light must be required for its growth.

In order to verify this, the same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

The results of this experiment must confirm that the algae exposed to light grows better than the algae that was not exposed to light.
