Intro to Biology Test Questions with
Correct Answers
Mutation - ANSWERSA change in the DNA of a gene.
Homeostasis - ANSWERSProcess where organisms keep an internal environment
constant to survive. Ex. Sweating when hot, shivering when cold.
Reproduction - ANSWERSOrganisms make more of their own kind.
Biology - ANSWERSThe study of life.
Growth - ANSWERSAdding cells and mass to an organism.
Development - ANSWERSAll the changes that take place over an organisms lifetime.
DNA - ANSWERS(Deoxyribonucleic acid) The molecule that carries the directions for
inheritance.
Heredity - ANSWERSThe passing of traits from parents to offspring.
Metabolism - ANSWERSAll the chemical reactions that occur in an organism in order to
carry out life processes.
Cell - ANSWERSFundamental unit of life. Living matter enclosed by a barrier that
separates the cell from its surroundings.
Evolution - ANSWERSChange in the inherited characteristics of a species over multiple
generations.
Control Group - ANSWERSDoes not receive special treatment (the variable) and is
used as a comparison for the experimental group.
Stimulus - ANSWERSA change in the environment that causes an organism to respond.
Independent Variable - ANSWERSThe factor or variable that is changed in the
experiment. (Graphed on the X axis.)
Dependent Variable - ANSWERSThe variable that is measured in the experiment.
(Graphed on the Y axis)
