Biology is the study of life—the structure, function, growth, origin, and evolution of living things. Biology and chemistry work together to create what many people think of as "science." And passing Biology 101 in college is the entryway to further study in the sciences - if you can't do well in it, you aren't moving ahead. The Complete Idiot's Guide® to College Biology follows the curriculum to Biology 101 so closely that it serves as a perfect study guide to it, and it's also great for the AP Biology and SAT Subject Biology exams that high school students are taking in droves. Students can turn to it when their textbooks are unclear or as an additional aid throughout the semester. The guide covers: • Complicated processes such as photosynthesis and cellular respiration • Explanations of complex biology, from DNA to ecosystems • Offers online extras, including a chapter on microbes and an extended glossary Suitable for the new learner or as a refresher for former students, The Complete Idiot's Guide® to College Biology brings biology to the reader in a relaxed, accessible way.
