Biology benchmark 2 semester exam fall 24

Question

A student Had their wisdom teeth removed and their mouth is swollen.Their Doctor tells them to rent their mouth with a warm salt water solution every few hours.How does the salt water solution help reduce the swelling in the student's mouth
The salt water is A psychotonic solution in the Swollen sails in the student's mouth will take in water through osmosis
The saltwater is a hypotonic solution in the swollen.cells in the student's mouth will release water through difusion
The salt water is a hypertonic solution and the swollen sails in the student's mouth will take in water through diffusion
The salt water is a Hypertonic solution and the swollen sales in the student's mouth were released water through osmosis

Answer 1

In this scenario, the correct explanation is:

The salt water is a hypertonic solution and the swollen cells in the student's mouth will release water through osmosis.

Here's why:

• A hypertonic solution has a higher concentration of solutes (in this case, salt) compared to the cells in the swollen area of the mouth.
• When you rinse with the hypertonic salt water solution, water will move out of the swollen cells (which have a lower concentration of solutes) and into the salt water (the higher solute concentration) to try to balance the concentrations on both sides of the cell membranes.
• This process is called osmosis.
• By drawing water out of the swollen cells, the hypertonic solution helps to reduce swelling in the tissues.

So rinsing with salt water reduces swelling due to the osmotic effect of the hypertonic solution.
