Use this information to answer the question:  A newly discovered unicellular, aquatic (i.e., lives in water) animal species has cells with a solute concentration of 45% solutes.  Understanding the process of osmosis and the effects of isotonic, hypotonic, and hypertonic solutions on cells, you are attempting to determine the safest solution for transport of this organism back to your laboratory for further study (you want to keep it alive!).  You have available the following solutions:  10% solutes, 43% solutes, and 85% solutes.  Answer the following question: Which of the following is most likely to occur when you place the cell in the 43% solution?
