These 106 in-depth tutorials are designed to illustrate and explain some of the many complex topics in biology. Each tutorial has four elements: an introduction that describes the topic to be illustrated and puts it into a broader context, a detailed animation that clearly illustrates the topic (there are a few tutorials that include simulations or other types of content, rather than animations), a conclusion that summarizes what you should have learned from the animation, and a quiz on the topic covered. The clear presentation of complex topics make these tutorials a powerful learning tool, be sure to work through them in their entirety for the best benefit. New to the Seventh Edition are 20 Key Experiment tutorials that expand upon some of the most important experiments depicted in the book, as well as 10 additional new tutorials. All the animated activities include textbook references, making it easy for you to look up a topic in the text for further explanation. For details on how the tutorials work, click the Help button on the Animation tab of a tutorial.
Note: An 'E' indicates an experiment tutorial. These correspond to experiment figures in the textbook.
