Define Electron Found outside nucleus, have negative charge
Define Proton Found inside nucleus, have positive charge
Define Neutron Found inside nucleus, have no charge
Define Element Made up of one type of Atom
Define Molecule Atoms of the same element bonded together i.e) O2
Define Compound Made up of two or more different elements that combine chemically i.e) H20-water; CO2; CO
Define Mixture Made of substances that combine physically Can be solids, liquids or gases or combinations of both i.e) sand and baking soda; chocolate chip ice cream

Explain why blood is a suspension Blood cells can sink to the bottom without being "mixed" by circulation of blood flow.
What are the three reasons water is important? living things are made of more than 50% water needed for chemical reactions to occur used to transport materials throughout the organism
Define carbohydrates supply energy for cell process made up of sugar and starches-like glucose
What are the three characteristics of lipids? fats and oils; do not mix with water release a larger amount of energy than carbohydrates; harder to break down found in cell membranes; make cell membrane selectively permeable b/c fats and oils do not mix with water
Since lipids have more energy stored in their bonds why does the body get more use-able energy from carbohydrates your body converts them to glucose and your body runs on glucose
What are proteins made of? amino acids
What are the two uses or proteins in the body? make up many structures like muscle make up enzymes
What are nucleic acids? store coded information for cells in DNA
