Chapter 2 The Chemical Context of Life Lecture Outline Overview: Chemical Foundations of Biology Living organisms and the world they live in are subject to the basic laws of physics  and chemistry. Biology is a multidisciplinary science, drawing on insights from other sciences. Life can be organized into a hierarchy of structural levels. At each successive level, additional emergent properties appear. Concept 2.1 Matter consists of chemical elements in pure form and in combinations called compounds Organisms are composed of  matter. Matter is anything that takes up space and has mass. Matter is made up of elements. An  element  is a substance that cannot be broken down into other substances by  chemical reactions. There are 92 naturally occurring elements. Each element has a unique symbol, usually the first one or two letters of the name.  Some of the symbols are derived from Latin or German names.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
