Life on earth is complex and diverse, so it may surprise you to learn that all life on earth has some similar ingredients. Without these ingredients, there would be no life on this planet, at least, not the way it is now. In this module, you will explore the importance of these ingredients and how they function together to build dynamic organisms and biological systems. First, you will learn about the properties of water and how they impact biological studies. Next, you will study what makes something an acid or a base, and why the measurement on the pH scale is so important. Then, you will explore organic molecules - some of which you will find in your own body. At the end of the module, you will learn more about chemical reactions and related enzymes.
Part of your study of biology will include this module on biochemistry, or the intersection between the study of biology and chemistry. Before you begin, consider how the various branches of science intersect one another. From your study of biology so far, what other branches of science have you also studied? From memory, make a short list of some concepts that intersect between biology and the other branches of science, like Earth science, physics, chemistry.
