Scientific Method - ANSW-A process used to investigate and explain a natural phenomenon
Hypothesis - ANSW-a testable explanation
Scientific Theory - ANSW-A group of related hypothesis which have withstood extensive attempts to
falsify them
Evidence - ANSW-Direct and repeatable observation
Controlled Experiment - ANSW-An experiment in which only one variable is manipulated at a time.
Cell-based - ANSW-All life is composed of one or more cells
Contains genetic material - ANSW-DNA
Characteristics of living organisms - ANSW-Uses genetic info to reproduce

Characteristics of living organisms - ANSW-Convert molecules into new biomolecules
Characteristics of living organisms - ANSW-Extract energy from environment
Characteristics of living organisms - ANSW-Regulate internal environment
Element - ANSW-Cannot be broken down to other substances by chemical
Atom - ANSW-single unit of an element
Proton - ANSW-positively charged particle
Neutron - ANSW-A subatomic particle that has no charge and that is found in the nucleus of an atom
Electron - ANSW-negatively charged particle
Atomic Number - ANSW-the number of protons in the nucleus of an atom

Single bond - ANSW-a covalent bond in which two atoms share one pair of electrons
Double bond - ANSW-A chemical bond formed when atoms share two pairs of electrons
Structural Formula - ANSW-a formula that shows the arrangement of atoms in the molecule of a
compound. H-H
