Explanation:
When we want to do an experiment we must establish which will be the experimental group (one where the factor tested in the experiment is applied) and a control group (one that was set exactly the same as the experimental group but the factor tested in the experiment was not applied). In the case shown in the question above, the student wants to develop an experiment that tests whether fluoridated water is effective in preventing tooth decay.
This student's experimental group is a group of people who consume water with the addition of fluor (factor tested in the experiment) in their composition, whereas their control group will be a group of people who do not consume water with the addition of fluor in their composition.

Explanation:
MyPlate is a nutritional guide developed by the U.S. Department of Agriculture (USDA), which indicates a healthy diet without hard dietary restrictions. MyPlate represents an easy food plan that emphasizes the importance of five different food groups represented by grains, fruits, vegetables, proteins and dairy sources. The MyPlate model uses a plate and a glass in order to indicate the best way to distribute these five food groups over the daily meals. These guidelines recommend that half of the plate be filled with fruits and vegetables, 1/4 with grains, and 1/4 with protein.
