Artichokes (Cynara cardunculus var. scolymus) are a diploid species that has a total of 34 chromosomes (2n = 34). At different stages of the cell cycle in an actively dividing cell from an artichoke, you observe that the number of chromosomes present changes over time from 34 to 68 to 34 in one final daughter cell. What type of division is this cell undergoing? [ Select ] ["Mitosis", "Meiosis"] If this cell was undergoing mitosis, what would be the number of chromosomes at the end of S-phase? [ Select ] ["34", "51", "17", "102", "68"] If this cell was undergoing mitosis, what would be the number of chromosomes at the end of telophase? [ Select ] ["51", "68", "102", "17", "34"] If this cell was undergoing meiosis, what would be the number of chromosomes at the end of S-phase? [ Select ] ["17", "102", "68", "51", "34"] If this cell was undergoing meiosis, what would be the number of chromosomes at the end of telophase II? [ Select ] ["34", "68", "17", "102", "51"]
