Available with Prescott, Harley, and Klein's Microbiology, Seventh Edition, are more than 150 animations to harness the visual impact of microbiology processes in motion. These animations can be found on the ARIS Presentation Center at aris.mhhe.com. Since you control the action, these 3-D clips make great review and study tools! Each animation includes five questions to test your understanding of the concepts. Instructors can also import the animations into classroom presentations or online course materials!
