Question

which of the following describes an equal concentration of solutes in both the solution and the cell? hypertonic hypotonic isotonic

Explanation:

To solve this, we recall the definitions of tonicity terms:

• Hypertonic: Solution has higher solute concentration than the cell.
• Hypotonic: Solution has lower solute concentration than the cell.
• Isotonic: Solution and cell have equal solute concentrations.

The question asks for equal solute concentration, so the correct term is isotonic.

Answer:

C. isotonic (assuming the options are labeled as A. hypertonic, B. hypotonic, C. isotonic; if the third option is "isotonic" as per the image, the answer is the option with "isotonic", e.g., the third option (if ordered as hypertonic, hypotonic, isotonic) or the one labeled "isotonic".)
