You place a potato cube in a sugar solution and after 1 hour its mass is unchanged. Which is the best interpretation?
A student finds mean percentage mass changes at concentrations: 0.0M +10%, 0.1M +8%, 0.2M +4%, 0.3M 0%, 0.4M -5%. Which concentration is approximately isotonic to the potato?
When designing a potato osmosis experiment, which variable should be the independent variable?

If a potato piece gains mass after placing in a solution, what does that indicate about the solution relative to the potato cell sap?
Which statement about water potential is correct?
What is osmosis?
A student calculates percentage change in potato mass using: percentage change = (change in mass / original mass) × 100. If original mass = 5.0 g and final mass = 4.6 g, which is the correct percentage change?
