Question

9. A food scientist baked one cookie dough sample at 350 degrees F for 13

Answer 1

Answer:

There is no control.

Explanation:

If the scientist was testing something based on the different temperatures, they would need the amount of time in the oven to be the same for each cookie so that they can compare them. Without the times being the same, the scientist would not be able to tell whether the temperature or the time in the oven caused the differences in the cookies.
