Biology: Introduction to energy

Energy is defined as the ability to do work. Energy can be found in many things and can take different forms. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. Energy is never lost, but it can be converted from one form to another.

Biology

Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.

Laws of thermodynamics

Although it might be fun to be exempt from the laws of physics (flying, anyone?), it turns out that cells and organisms are in fact subject to these laws, just like any other type of matter. Learn more about the laws of thermodynamics and how they relate to energy transfers in biological systems.
