Osmosis Challenge

Use the words: isotonic, hypotonic, hypertonic If you soak your hands in dishwater, you may notice that your skin absorbs water and swells into distinct wrinkles. This is because your skin cells are _______________ to the _______________ dishwater.

Use the words: isotonic, hypotonic, hypertonic You decide to buy a new fish for your salt water aquarium. When you introduce the fish into its new tank, the fish shrinks and dies. You later learn that it was a fish from freshwater. Based on what you know of tonicity, the most likely explanation is that unfortunate fish went from a(n) _______________ solution into a(n) _______________ solution.

A student places a dialysis tubing containing sucrose solution into a beaker containing a solution. The total mass of tubing was initially 2.5g, but after 39min in the solution, the mass was 1.75g. Was the solution hypertonic, hypotonic, or isotonic compared to the sucrose solution?

HINT: Draw the scenario The cells that make up object are 44% salt. If placed in 80% water, the cells are placed in what type of solution? What will happen to the cell?

What will happen to the cell? What type of solution is below?
