Very... Reproduction at both the molecular level to help maintain and repair itself through production of cells is important for self-preservation. Additionally reproduction allows survival of genetic material to offspring.
An internal stimulus is a factor that usually occurs inside of an organism. For example, your body can sense dehydration or a lack of energy inside of you
Initially, in terms of tonicity, the solution in side A with respect to that in side B is isotonic.
- A solution is considered to be isotonic if it possesses the same osmolarity, or level of solute concentration, as another solution. When these two solutions are placed on either side of a membrane that is only partially permeable to water, water will flow in an equal amount from one solution into the other. The result is that there is no water flow at all between the two solutions, despite the fact that water is travelling in both directions.
- A solution is considered hypotonic when it has a lower level of solute concentration in comparison to another solution.
- A solution is considered hypertonic when it has higher osmolarity compared to another solution.
In the given questions, the solution in the two arms of the U- tube has the same osmolarity and therefore is isotonic.

Cohesive water molecules stick together as surface tension pushes them up the roots
The ecosystem would be greatly effected, most likely causing the system to fail, and could lead to the death of a species, or a very large population boost, or even worse.
