To determine which solution is isotonic with the carrot, we need to look for the point on the graph where the line of best fit crosses the x-axis (option 3).
In this context, the x-axis represents the concentration of the solution, and the y-axis represents the change in mass of the carrot. The point where the line of best fit crosses the x-axis indicates the concentration of the solution at which there is no net gain or loss of mass for the carrot.
This point represents the isotonic solution because isotonic solutions have the same concentration of solutes as the carrot, resulting in no net movement of water into or out of the carrot cells.
Once we graphed our result how did we know which solution was isotonic with the carrot?
1. where the line of best fit was at its lowest
2. where the line of best fit crossed the y axis
3. where the line of best fit crossed the x axis
4. where the line of best fit was at its highest
