It is the variable that you have control over and that doesn't have to depend on another variable.

The <em>independent </em>variable is the variable that you change and control in your experiment. The <em>dependent</em> variable is the one you don't have control over and is affected by how the independent variable reacts.

For Example:
Let's say you're doing an experiment seeing how different sugars affect the density of cupcakes. The type of sugar you add would be the independent variable, because you are choosing it. The density would be the dependent variable, since it depends on the sugar used.

Answer:

The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

hope this helps
