Question

in the graph above, the independent variable is the variable which is graphed on the is the and is graphed on the . when this person ate a complex carbohydrate meal, their blood glucose level spiked at hour after their meal. when they ate a protein meal, their blood glucose level increased and decreased much than with their carbohydrate meal. blood glucose level (measured in mg of glucose per liter of number of hours elapsed since eating complex carbohydrate protein

Explanation:

Step1: Identify Independent Variable

In a graph, the independent variable is the one that is manipulated or changes on its own, usually on the x - axis. Here, the x - axis is labeled "Number of hours elapsed since eating", so the independent variable is the number of hours elapsed since eating.

Step2: Identify Axis for Independent Variable

The independent variable (number of hours elapsed since eating) is graphed on the x - axis.

Step3: Identify Dependent Variable

The dependent variable depends on the independent variable. Here, the graph is about blood glucose level, so the dependent variable is blood glucose level.

Step4: Identify Axis for Dependent Variable

The dependent variable (blood glucose level) is graphed on the y - axis.

Step5: Analyze Complex Carbohydrate Meal Spike Time

From the graph (complex carbohydrate curve), we can see that the blood glucose level spikes at 2 hours after the meal.

Step6: Analyze Protein Meal vs Carbohydrate Meal

When looking at the protein and complex carbohydrate curves, the protein meal's blood glucose level increased and decreased much less than with the carbohydrate meal.

Answer:

1. Independent variable: Number of hours elapsed since eating; graphed on: x - axis
2. Dependent variable: Blood glucose level; graphed on: y - axis
3. Complex carbohydrate meal spike time: 2 hours
4. Protein meal glucose level change: less
