In the student's experiment;
- the control group is bacteria grown at 98.6°F
- the experimental group is bacteria grown at 95°F, 100°F, and 108°F.
<h3>What are control and experimental groups in an experiment?</h3>

2.)Polycyclic aromatic hydrocarbons (PAHs); food contamination by PAHs arises from processing of food (drying, smoking) and cooking of food at high temperatures (grilling, frying, roasting).
3.) Heterocyclic amines (HCAs), many of which are present in burnt and charred foods, especially blackened meat.
