Question
Consider a desert pupfish that is adapted to living in Salt Creek, where the salt concentration far exceeds that of the ocean. Imagine that this pupfish is suddenly moved to a freshwater environment. Which of the following statements is most accurate? The new environment would be hypertonic to the pupfish's cells. The new environment would be hypotonic to the pupfish's cells. The new environment would be more acidic than the pupfish's cells. The new environment would be more basic than the pupfish's cells. The new environment would be colder than the pupfish's cells.Explanation / Answer
A solution is a mixture of solute and solvent (e.g. salt and water). When the concentration of solute (salt) is more than the solvent (water), the solution is known as hypertonic. While as when the concentration of solvent is more than the solute, then the solution is known as hypotonic. Hypotonic solution will have less osmotic pressure as compared to the hypertonic pressure.
Hypertonic solutions are more acidic than the hypotonic solution , also hypotonic solutions are more cooler than than hypertonic, the former has more water molecules as compared to latter.
In the current example, when pupfish which is adapted to salty environment (cells are living in hypertonic conditions with greater osmotic pressure), is transferred to freshwater environment (Less osmotic pressure-hypotonic), then water will move from fresh water into the cells of pupfish.
Therefore, the correct options are: B, D,E
