What is concentrated salt solution added to the tube with the cheek cells?

Adding a concentrated salt solution to the solution containing cheek cells will cause the water to move outside the cells by osmosis. The cheek cells are at a higher water potential than the outside solution so, the water will move out, down the water potential gradient, until an equilibrium is reached.

Hope that answers the question, have a great day!

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

no but i do not usually comment or use my voice that much when it comes to social media
