5/15/2017Mitosis and Meiosis17/31CorrectMitosis goes on continuously in most parts of the body, whereas meiosis takes place only in the gonads.Part BANSWER:CorrectMeiosis I is the only time that chromosomes line up by homologous pairs.Part CClick here to review the figureANSWER:mitosis onlymeiosis I onlymeiosis II onlyeither mitosis or meiosis Ieither meiosis I or meiosis IItelomeretetradcentromerecentrosomechromosome
5/15/2017Mitosis and Meiosis18/31CorrectThe centromere is the point of attachment between two duplicated chromosomes.Part DANSWER:CorrectIf the hypothetical organism has 5 chromosomes in one of its gametes, then it must have 10 chromosomes in a body cell. Just before mitosis, thechromosomes in a body cell are duplicated, but the sister chromatids remain joined together. So you will see 10 (duplicated) chromosomes in atypical body cell.Part EClick here to review the figureANSWER:5101520the answer cannot be determinedthe start of meiosis Ijust after meiosis Ithe start of mitosisthe start of meiosis IIjust before mitosis
5/15/2017Mitosis and Meiosis19/31CorrectWe can see that the chromosomes are duplicated and lined up by homologous pair. That only happens at the start of meiosis I.BioFlix Quiz: MeiosisWatch theanimationbefore answering the questions.Part AMeiosis starts with a single diploid cell and producesHint 1.Review the animation or your Study Sheet for MeiosisANSWER:CorrectMeiosis produces four haploid cells.Part BA cell preparing to undergo meiosis duplicates its chromosomes duringHint 1.Review the animation.ANSWER:four haploid cells.two haploid cells.eight haploid cells.two diploid cells.four diploid cells.
5/15/2017Mitosis and Meiosis20/31CorrectChromosomes are duplicated during interphase.Part CDuring prophase I of meiosis,Hint 1.Review the animation.ANSWER:CorrectHomologous chromosomes stick together in pairs during prophase I.Part DThe correct order of events during meiosis isHint 1.Review the animation or your Study Sheet for Meiosis.ANSWER:interphase.anaphase I.metaphase I.meiosis II.prophase I.there are two daughter cells, each with 23 chromosomes.the homologous chromosomes separate and move towards opposite poles.there are four haploid daughter cells.homologous chromosomes stick together in pairs.chromosome pairs are positioned in the middle of the cell.metaphase I, prophase I, telophase I, anaphase I, cytokinesi
