Imagine that an amobea is placed in a solution of salty water. The concentration of salt in in the solution is greater than the salt concentration of the amobea's watery cytoplasm. What will happen,and why? Be sure to use the proper science terms to communicate your understanding.

Because of the concentration gradient between the amoeba and surrounding water, there will be a driving force for salt to enter into the amoeba via osmosis. However, the membrane of the amoeba will not allow salt to pass through. Because of this, water will leave the amoeba until the concentration of salt on both sides of the membrane is the same, eliminating the driving force.

If the salt water is of a significantly higher concentraion than inside the amobea water will flow out of the cell (cells can cope with a bit of difference as they can actively transport small molecules through the membrane against a gradient).
The water moves out due to the tendancy to move from an area of high to an area of low concentraion (entropy).
As water is essential to the biochemistry of cells the amoeba will shrivel and eventually die.

The amobea will shrivel up. The water will flow by osmosis from the higher concentration to the lower concentration.

Hi. The poor amoeba will lose it's water through osmosis and die.
