(WGU C190) BIO 1010 INTRO TO BIOLOGY FINAL EXAM REVIEW Hypothesis - answersa supposition or proposed explanation made on the basis of limited evidence 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. hydrophilic molecules - answersDo not cross the membrane easily, such as ions and polar molecules. DNA replication occurs - answersthe S phase of interphase in both somatic and reproductive cells covalent bond - answersA chemical bond that involves sharing a pair of electrons between atoms in a molecule hydrogen bond - answersAttraction between a slightly positive hydrogen atom and a slightly negative atom. ionic bond - answersA chemical bond resulting from the attraction between oppositely charged ions.
