Answer:

The answer to these questions are the following:

1. sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter

2. distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameter

Osmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:

1. In a hypotonic solution, the cells will become turgid  

2. In an isotonic solution, the cells will become flaccid.  

3. In a hypertonic solution, the cells will shrink (plasmolysis)

When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water loss

When plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.

The sun shining on a tidal pool during a hot day heats the water. As some water evaporates, the pool becomes saltier, causing.
ludmilkaskok [199]

As water evaporates off salt water, the water gets saltier, and dissolved oxygen in the water reduces.

<h3>Dissolved oxygen and solute concentration</h3>

There is an inverse relationship between the dissolved oxygen in water and the concentration of solute.

Thus, as water evaporates off the tidal pool, available free oxygen decreases accordingly just as the water becomes more salty.

In other words, the more water in a solution, the more free oxygen, and vice versa.
