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.

Cosmology by definition is the branch of astronomy involving the origin and evolution of the universe. It is the study of how the universe is formed from the big bang theory to other theories pushed by scientists. It also studies about the parts and components of the universe.
Answer;
Nitro.
Explanation:
By far, the most abundant gas in the Earth's atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%. Although humid air seems like it contains a lot of water, the maximum amount of water vapor that air can hold is only about 4%.
Speed = distance / time = (420 x 1000) / (6 x 3600) = 19.44 m/s
