Hypothesis - answersa supposition or proposed explanation made on the basis of
limited evidence
... [Show More] as a starting point for further investigation.
Theory - answersA hypothesis that has been tested with a significant amount of data
Independent Variable - answersThe experimental factor that is manipulated; the
variable whose effect is being studied.
Dependent Variable - answersThe measurable effect, outcome, or response in which
the research is interested.
Control group - answersIn an experiment, the group that is not exposed to the
treatment; contrasts with the experimental group and serves as a comparison for
evaluating the effect of the treatment.
RNA transcription - answersTransfers DNA gene base sequence to a
complementary base sequence of an mRNA
protein translation - answersthe process in which the genetic code in mRNA is used
to assemble amino acids in the correct sequence to make a protein
hypertonic solution - answersSolute concentration is greater than that inside the cell;
cell loses water
hypotonic solution - answersa solution that causes a cell to swell because of
osmosis
Mitosis - answerscell division in which the nucleus divides into nuclei containing the
same number of chromosomes
Meiosis - answersa type of cell division that results in four daughter cells each with
half the number of chromosomes of the parent cell, as in the production of gametes
and plant spores.

polar molecules.
DNA replication occurs - answersthe S phase of interphase in both somatic and
reproductive cells
