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

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.
To determine which solution was isotonic with the carrot, you would need to examine the graph of your results. Here's how you can use the different features of the graph to find the isotonic solution:
1. The line of best fit being at its lowest point: If the line of best fit is at its lowest point on the graph, it indicates the concentration at which there was no net movement of water into or out of the carrot cells. This concentration is known as the isotonic solution. Therefore, the solution where the line of best fit is at its lowest would be the isotonic solution.
2. The line of best fit crossing the y-axis: When the line of best fit crosses the y-axis, it represents the concentration of the solution where there was no change in the mass of the carrot. This concentration corresponds to the isotonic solution.
3. The line of best fit crossing the x-axis: If the line of best fit crosses the x-axis, it indicates the concentration of the solution where the mass of the carrot is equal to zero. This concentration is known as the hypotonic solution, where water enters the carrot cells and causes them to swell. The isotonic solution would be the one before the line crosses the x-axis.
4. The line of best fit being at its highest point: If the line of best fit is at its highest point on the graph, it suggests the concentration at which the carrot lost the most mass. This concentration corresponds to the hypertonic solution, where water is leaving the carrot cells. The isotonic solution would be the one before the line reaches its highest point.
In summary, the isotonic solution can be determined by examining the graph and identifying the point where the line of best fit is at its lowest or before it crosses the x or y axis.
To determine which solution on the graph is isotonic with the carrot, we need to understand the characteristics of an isotonic solution. An isotonic solution has the same concentration of solutes as the reference solution, which in this case is the carrot.
When graphing the result, there are several indicators we can look for to identify the isotonic solution. Here's an explanation for each option:
1. Where the line of best fit was at its lowest: This option suggests that the lowest point on the graph corresponds to the isotonic solution. However, the position of the line of best fit does not necessarily indicate the isotonicity of a solution, as it is more related to overall regression analysis.
2. Where the line of best fit crossed the y-axis: This option implies that the intercept on the y-axis signifies the isotonic solution. However, the y-intercept is typically related to the initial conditions or starting point of the experiment, and not necessarily the isotonicity of the solution.
3. Where the line of best fit crossed the x-axis: This option suggests that the point where the line of best fit intersects the x-axis represents the isotonic solution. Since the x-axis corresponds to the independent variable (usually concentrations in this case), the point of intersection would likely indicate the concentration that makes the solution isotonic with the carrot.
4. Where the line of best fit was at its highest: This option proposes that the highest point on the graph corresponds to the isotonic solution. However, similar to option 1, the position of the line of best fit does not specifically indicate the isotonicity of a solution.
In summary, the option that would likely help determine the isotonic solution with the carrot when graphing the result is option 3. The point where the line of best fit crosses the x-axis would represent the concentration of the solution that is isotonic with the carrot.
