The art program features precise illustrations in full-color. Full-color photographs appear alongside the relevant exercise, allowing students to clarify their experiments and better interpret their results. Twenty-five new photos have been included, and new illustrations have been added to Exercises 9, 11, 25, 26, 27, 29, 30, 40, and 44 to further illustrate and explain complex procedures. Expected Results or Hypothesis Section in each exercise’s Laboratory Report encourages students to speculate on the outcome of experimental procedures and to formulate a hypothesis when appropriate. Clinical Application questions, which have a clinical basis or are derived from a clinical situation, have been added to each Laboratory Report to help students draw connections between what they learn in lab and allied health careers. Prelab questions, multiple choice and true/false, are available online for laboratory instructors' use to ensure their students prepare adequately for each assigned laboratory exercise. Pre-lab questions are also available and assignable in MasteringMicrobiology®. Exercise on Transformation of Bacteria has been extensively revised to incorporate use of pGLO to introduce students to this important tool used in microbiology. Eye-catching full-color design engages the student while highlighting this manual’s trademark clear organization and presentation.
