7: C
8: B
9: A
7 the independent variable is almost always time
8 the controlled variable is what you choose to be affected
9 the responding variable is the variable affected by the independent variable, for this example it is time heated and the number of unpoped kernels

The terms with respect to their definitions are matched below:
- Independent variable: The time the popcorn is cooked.
- Controlled variable: The brand of popcorn.
- Responding variable: The number of unpopped popcorn kernels.
What is an Independent variable?
An independent variable may be defined as a variable that stands isolated and isn't altered by the other variables you are trying to measure in your experiments.
A controlled variable may be defined as a variable that remains unchanged during the course of whole experiments.
A responding variable may be defined as a variable that responds according to the effect of controlled and independent variables.
Therefore, it is well described above.
