Answer and Explanation:
The answer would be: Breakfast
Breakfast would be the constant of this scenario because this doesn't change. The time of day (for eating eggs) will always be in the morning, so that wouldn't change.
Eating eggs would be the independent variable because you can change this value. This could be a different food or an amount of the food that is being eaten.
The grades would be the dependent variable because the score depends on the eating of eggs.
