To help make ideas about energy more concrete, for example, the new unit will use a variety of analogies from more familiar physical systems (e.g., combustion and charging a cellphone battery) to help students understand those same energy - releasing and energy - requiring chemical reactions and energy transfer when they occur in living organisms (e.g., cellular respiration, creating a charge across a membrane in mitochondria and nerve cells) where the reactions are more complex and difficult to observe.

The fields within biology are further divided based on the scale at which organisms are studied and the methods used to study them: biochemistry examines the fundamental chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues and organ systems of an organism; and ecology examines how various organisms interrelate.
