Koalas benefit from tress because then can climb on them to keep away from danger such as other ground predators, Trees can also serve as a food source for them to eat in day to day life.
This would be an example of embryological development.
Answer:
<em>Water will move out of a cell.</em>
Explanation:
A hypertonic solution will have higher solute concentration and lesser solvent concentration. If a cell is placed in such a solution, then the concentration of the solvent will be more inside of the cell as compared to outside of the cell. As a result, the solvent will move out of the cell. If an excess of solvent is lost, the cell might shrink to dangerous levels.
Hence, from the above description we can justify that water will move out of a cell which is placed in a hypertonic solution.
The answer is (b.) ATP and calcium
ATP (Adenosine triphosphate) and Calcium participates in the muscle movement. In a muscle contraction, Calcium ions are released to initiate upon the depolarization of the membrane which is induced by nerve impulses. While the ATP is required to the shortening of actin and myosin filament crossbridges.
