Dependent Variable - Answer: Variable that is observed and that changes in response
to the independent variable
Hypothesis - Answer: Possible explanation for a set of observations or possible
answers to a scientific questions
Independent Variable - Answer: Factor in a controlled experiment that is deliberately
changed
Inference - Answer: A logical interpretation based on prior knowledge and experience
Qualitative Data - Answer: Information that is written or observed
Quantitative Data - Answer: Information in the form of numbers
Theory - Answer: Well-tested explanation that unifies a broad range of observations
and hypotheses, and enables scientists to make accurate predictions about new
situations
Activation Energy - Answer: Energy that is needed to get a reaction started
Amino Acid - Answer: Compound with an amino group on one end and a carboxyl
group on the other end

Lipid - Answer: Macromolecule made mostly from carbon and hydrogen atoms;
includes fats, oils, and waxes
Nucleic Acid - Answer: Macromolecules containing hydrogen, oxygen nitrogen, carbon,
phosphorus
Nucleotide - Answer: Subunit of which nucleic acids are composed; made up of 5-
carbon sugar, a phosphate group, and a nitrogenous base
Polymer - Answer: Molecules composed of many monomers; makes up
macromolecules
Product - Answer: Elements or compounds produced by a chemical reaction
Protein - Answer: Macromolecule that contains carbon, hydrogen, oxygen, and nitrogen
Reactant - Answer: Elements or compounds that enter into a chemical reaction
Substrate - Answer: Reactant of an enzyme catalyzed reaction
Cell - Answer: Basic unit of all forms of life
Cell Membrane - Answer: Thin, flexible barrier that surrounds all cells; regulates what
enters and leaves the cell
Cell Wall - Answer: Strong, supporting layer around the cell membrane in some cells
