Question

3. What does this tell you about the relative tonicity (osmotic pressure) between the contents of the tubing and the solution in the beaker?

Answer 1

Answer:

Please look in the explanation section

Explanation:

Tonicity is defined as the gradient of the osmotic pressure, which is the potential of two solutions that are isolated by a semipermeable membrane. This term is generally used when detailing the cellular response of cells that are submerged in a solution. Tonicity is affected by solutes that are unable to cross the membrane, thereby exerting osmotic pressure. The solutes that cross the membrane do not affect the tone.

On the other hand, the term hypertonic means a higher concentration, defining itself as a solution with a high concentration of solutes that are found outside the cell. If a cell is immersed in this type of solution, the water moves out of the cell to achieve balance between solutes.

The hypotonic term has to do with a lower concentration. These solutions are characterized by having a low concentration of solutes, in this way, water will enter the cell and produce inflammation.

Finally, an isotonic solution is a solution in which the concentration is the same as the concentration of the solutes in other solutions. For example, if the concentration of the water and solute molecules are the same in an external solution as in the cell content. The water molecules spread within the plasma membrane in both directions, and in this way, the cell will neither gain nor lose water.
