What was the measured variable in Homer’s experiment about salt intake and heart rate?
The type of food Homer ate
The daily measurement of heart rate
The amount of salt in the food
The number of days in the experiment

The week Homer avoided salty foods
The week Homer ate all the salty foods he normally eats
The week Homer exercised daily
The week Homer drank more water
