Caviar are the eggs of the fish. The eggs are stored in brine, or saltwater solution. Which statement describes the importance if storing the caviar in brine instead of distilled water?A. Distilled water would cause an isotonic environment for the eggs.B. Brine maintains equilibrium of water movement across the egg membrane.C. Distilled water would cause water to move outside of the egg membrane.D. Brine keeps the salt levels in the eggs higher than outside of the eggs.

Explanation:

Remember that in an isotonic environment, there is no net water movement, so there is no change in the size of the cell. That is because an isotonic solution is one that has the same osmolarity, or solute concentration, as another solution. If two solutions are separated by a semipermeable membrane, water will flow in equal parts out of each solution and into the other.

Now, distilled water is an example of a hypotonic solution. A solution that contains fewer dissolved particles (such as salt and other electrolytes) than is found in normal cells. On the other hand, the saltwater you use to brine any food is typically considered a hypertonic solution.

Thus, we can conclude that the correct answer is:

Answer:

D. Brine keeps the salt levels in the eggs higher than outside of the eggs.
