4 question
what is the dependent variable of this study?
answer

Explanation:

1. By observing the graph, metabolism of protein peaks around 2 - 3 hours.
2. Lipids generally have a slower metabolism rate compared to proteins and carbohydrates.
3. We need to compare the carbohydrate and protein metabolism curves on the graph to find when carbohydrate metabolism is higher.
4. The dependent variable is what is being measured, which in this case is the % of food metabolized.

Answer:

1. Between 0 - 2 hours (by observing the graph where the carbohydrate metabolism curve is above the protein metabolism curve).
2. % of food metabolized.
