Answer 1

9. B — Meiosis (homologs pair during prophase I).
10. C — Both (metaphase in mitosis; metaphase I and II in meiosis).
11. B — Meiosis (reduces diploid to haploid).
12. A — Mitosis (maintains chromosome number).
13. A — Mitosis (occurs in somatic/body cells).
14. B — Meiosis (occurs in sex organs/germ cells).
15. C — Both (both have prophase, metaphase, anaphase, telophase; meiosis does PMAT twice).
16. C — Both (sister chromatids separate in mitosis and in meiosis II).
17. B — Meiosis (tetrads form during prophase I).
