100%.
1. Cell division in which the nucleus divides into nuclei containing
the same number of chromosomes - correct answer - Mitosis
2. The resting phase of mitosis. Cell grows, performs its normal
functions, and prepares for division; consists of G1, S, and G2
phases - correct answer - Interphase
3. The first gap, or growth phase, of the cell cycle, consisting of the
portion of interphase before DNA synthesis begins. - correct
answer - G1 Phase
4. The synthesis phase of the cell cycle; the portion of interphase
during which DNA is replicated. - correct answer - S Phase

5. The second gap, or growth phase, of the cell cycle, consisting of
the portion of interphase after DNA synthesis occurs.
6. Growth and preparation for mitosis - correct answer - G2 Phase
7. First and longest phase of mitosis, during which the chromosomes
become visible and the centrioles separate and take up positions
on the opposite sides of the nucleus - correct answer - Prophase
8. Cells that have left the cycle and cease dividing for a long time (or
permanently) - correct answer - G Zero (G0) Phase
9. Second phase of mitosis, during which the chromosomes line up
across the center of the cell - correct answer - Metaphase
10. The third phase of mitosis, during which the chromosome pairs
separate and move toward opposite poles - correct answer -
Anaphase
11. The final phase of cell division, between anaphase and
interphase, in which the chromatids or chromosomes move to

opposite ends of the cell and two nuclei are formed. - correct
answer - Telophase
12. Compare and Contrast Mitosis and Meiosis - correct answer -
Mitosis produces two diploid (2n) somatic cells that are
genetically identical to each other and the original parent cell,
whereas meiosis produces four haploid (n) gametes that are
genetically unique from each other and the original parent (germ)
cell.
13. Number of Chromosomes in Humans... - correct answer - 46
14. Haploid Number of Chromosomes In Humans - correct answer -
23
15. Control center of the cell; a part of the cell containing DNA and
RNA and responsible for growth and reproduction - correct
answer - Nucleus
