Chemistry  The study of the composition, structure, properties, and interactions of chemicals (matter).  Ex) biochemistry, organic  nuclear, analytical chemistries

Biology  The study of the structure, functions and processes of life.  Ex) medicine, genetics, taxonomy, ecology…..

Ecology  The study of interrelationship of organisms and their environments  Ex) global warming energy efficiency, resource use

homeostasis  a relatively stable state of equilibrium. (Ex. Body shivers to warm it up; Buffers in the blood to maintain pH)

metabolism  chemical changes in cells where energy is generated for the cells (and body's) processes Ex) slow/fast, sick=unbalanced
