Prepare a eight-to ten-slide PowerPoint Presentation discussing the roles of 5-7 subdisciplines of toxicology and the connection these subdisciplines have in occupational health and safety. Be sure to cite references on your last slide in proper APA format. You may either utilize the speaker's notes feature to type the script of what you would say if you were to present the PowerPoint to your classmates or record your voice speaking within the PowerPoint Presentation.
