Step-by-step explanation:
The primary role of most forensic scientists is to analyze evidence associated with crimes. They provide scientific evidence for use in courts by examining trace materials such as hair, blood, and other body fluids, as well as processing DNA found in different environments and materials. Forensic scientists also analyze other biological evidence, like insect larvae or pollen grains, left at crime scenes. In order to pursue a career in forensic science, students will typically need to take chemistry and biology courses, as well as some intensive math courses.
