When a solution has the same concentration as the fluid within the cell, that solution is:
A. acidic
Acidic: Acidity refers to pH, not solute concentration.
B. hypotonic
Hypotonic: A hypotonic solution has a lower solute concentration than the cell, causing water to enter the cell.
C. hypertonic.
Hypertonic: A hypertonic solution has a higher solute concentration and pulls water out of cells.
D. isotonic
Isotonic: Isotonic solutions have equal solute concentration and do not cause fluid shifts.
