Explanation:

Question 1

Mitosis phases are prophase, metaphase, anaphase, telophase. Interphase is not a mitosis phase (it's before mitosis), and cytokinesis is the division of cytoplasm after mitosis/meiosis. But the option that's not a mitosis phase but is in meiosis (cytokinesis occurs in both, but interphase is not a mitosis phase. Wait, the options: a. metaphase (mitosis phase), b. interphase (not mitosis phase, occurs before mitosis/meiosis), c. prophase (mitosis phase), d. cytokinesis (occurs after mitosis/meiosis, part of cell division process). Wait, the question is "not a phase of mitosis but is a phase of meiosis". Interphase is not a mitosis phase (mitosis phases are prophase, metaphase, anaphase, telophase), and interphase occurs before meiosis too. But maybe the intended answer is d? Wait, no. Wait, mitosis has prophase, metaphase, anaphase, telophase. Cytokinesis is the final step (not a phase of mitosis, but a process after). Meiosis also has cytokinesis. But interphase is not a mitosis phase. Wait, the options: b is interphase, d is cytokinesis. Maybe the question has a typo, but the marked answer is d. Let's check: Mitosis phases: PMAT (prophase, metaphase, anaphase, telophase). Cytokinesis is separate. Meiosis has cytokinesis. So cytokinesis is not a mitosis phase (mitosis phases are PMAT) but is part of meiosis (after meiosis I and meiosis II). So answer is d.

In meiosis, cell splitting (cytokinesis) occurs during telophase (after the nuclear division in telophase, the cell splits). Prophase is for chromosome condensation, anaphase for separation, metaphase for alignment. So telophase is when cells start to split.

Meiosis has 2 cycles: meiosis I and meiosis II. So the number of cycles is 2. But the marked answer is d (4), which is wrong. Wait, no: meiosis has one round of DNA replication and two rounds of cell division (meiosis I and meiosis II), so two cycles of division. So correct answer should be b. But the marked answer is d, which is incorrect. Wait, maybe the question is about cell division cycles. Meiosis has 2 divisions (meiosis I and II), so 2 cycles. So correct answer is b.

Answer:

d. cytokinesis
