t is 9 am in the morning and David has not eaten since dinner last night at 8 pm. He has fasted for 13 hours. He takes his first, or initial, blood glucose reading and it is 95 mg/dl. He then drinks an 8oz coke and eats 2 glazed donuts. At 9:45 am, 45 minutes after his initial reading, he pricks his finger again and records a blood glucose level of 125 mg/dl. An hour later, at 10:45 am, he takes his final blood sugar reading and it is 108 mg/dl. a. What specifically are the independent variable and dependent variable in this problem? b. Explain the spike for all the glucose readings (95mg/dl at 9 am, 125mg/dl at 9:45 am, and 108 10:45 am) c. How did the final glucose level (108 mg/dl) compare to the initial glucose level (95 mg/dl)?

a. What specifically are the independent variable and dependent variable in this problem?
b. Explain the spike for all the glucose readings (95mg/dl at 9 am, 125mg/dl at 9:45 am, and 108 10:45 am)
c. How did the final glucose level (108 mg/dl) compare to the initial glucose level (95 mg/dl)?
The dependent variable is the effect and it depends on other variables and changes as per the change in the independent variable. While the independent variable is cause and value does not change.
