A cell is placed in a solution and swells. This solution is:
Correct answer: C. Hypotonic to cell
- A. Isotonic to cell
- B. Hypertonic to cell
- C. Hypotonic to cell
- D. None of these
Explanation
Hypotonic refers to a solution with a lower concentration of solutes compared to another solution. In biological contexts, this can lead to water moving into cells, causing them to swell or expand.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
