Forensic entomologists study what to solve crimes?

Flies

Explanation:

Forensic entomology uses the study of insects to help criminal investigations. Forensic entomologists often help determine the time of death, especially when the circumstances of death are unknown. They do this using insect evidence. For example: when decomposition begins, blowflies infest a body, laying eggs that eventually hatch into fly larvae (maggots).

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
