Question

cells in our body are surrounded by extracellular fluid. a solution in which a cell exists that causes it to remain a normal size and shape is called a(n) ______.

Explanation:

To solve this, we analyze each option:

• Osmotic solution: Not a standard term for this context.
• Isotonic solution: Has the same solute concentration as the cell's interior, so water moves in and out equally, keeping the cell's size/shape normal.
• Hypotonic solution: Has lower solute concentration than the cell, causing water to enter and the cell to swell.
• Hypertonic solution: Has higher solute concentration, causing water to leave and the cell to shrink.

So the correct answer is the isotonic solution.

Answer:

B. isotonic solution
