Astudent is demonstrating how water moves across cell membrane to maintain homeostasis. the student uses dialysis bags, which are semipermeable and model cell membranes. the student fills each of the three bags with 100 ml of a 10% salt solution and ties the end of each bag. in beaker 1, the student places 200ml of a 5% salt solution. in beaker 3, the student places 200 ml of 20% salt solution.
what kind of environments are in beakers 1, 2, and 3?
a. beaker 1: hypertonic, beaker 2: hypotonic, beaker 3: isotonic
b. beaker 1: hypertonic, beaker 2: isotonic, beaker 3: hypotonic
c. beaker 1: isotonic, beaker 2: hypertonic, beaker 3: hypertonic
d. beaker 1: hypotonic, beaker 2: isotonic, beaker 3: hypertonic
