Please keep visiting us to download the learning aids. We plan to make Exercises and Review questions available here. Answers will not be provided. However, references to the section numbers (e.g., Section 1.2 for a section in chapter 1) will be given as hints to answers. If you are an instructor, you can obtain answers by contacting Dr. Nishith Tripathi (email@example.com) and Dr. Jeff Reed (firstname.lastname@example.org) with the subject line containing the words "Cellular Book ".
