Ever wondered how the food you eat becomes the energy your body needs to keep going? If DNA is a set of instructions in your cells, how does it tell your cells what to do? How does your brain know what your feet are doing? The theory of evolution says that humans and chimps descended from a common ancestor, but does it tell us how and why? We humans are insatiably curious creatures who can?t help wondering how things work ? starting with our own bodies. Wouldn?t it be great to have a single source of quick answers to all our questions about how living things work? Now there is.

From molecules to animals, cells to ecosystems, Biology For Dummies answers all your questions about how living things work. Written in plain English and packed with dozens of illustrations, quick?reference ?Cheat Sheets? and helpful tables and diagrams, it can get you quickly up to speed on what you need to know to:

• Understand how cells work
• Ge t a handle on the chemi stry of life
• Find out how food becomes energy
• Get to know your body?s systems
• Decode the secrets of DNA
• Find out what evolution is and isn?t and how it works
• Take a peek into the lives of bacteria
• Explore how viruses do their thing

Most basic biology books take a very round about approach, dividing things up according to different types of organisms. Biology For Dummies cuts right to the chase with fast?paced, easy?to?absorb explanations of the life processes common to all organisms. Topics covered include:

• How plants and animals get nutrients
• How organisms transport nutrients and expel waste
• How nutrients are transformed into energy
• How energy is used to sustain life
• How organisms breathe
• How organisms reproduce
• How organisms evolve into new life?forms
• How organisms create ecosystems

This book was an absolute life saver for me. I am a student nurse who never paid much attention to biologly at school (a few years ago now). So after much struggling and soulsearching I found this book. It has helped me greatly, it explains everything in really simplistic terms without all the jargon. It goes quite indepth and now I understand the basics I am sailing ahead through the course. It is a very useful study guide and would recommend it to anyone who has difficulty getting to grips with the basic anatomy.
