i need help , can yall see if im right and the ones that are not answered

Answer 1

Question 1

• Production of haploid cells - A) Meiosis.

Explanation - Meiosis is a special type of cellular division that leads to the formation of daughter cells that are haploid, meaning they have half the number of chromosomes as that of the parent cells.

• Cell division that gives produces cells for asexual reproduction, growth, repair and development - B) Mitosis.

Explanation - Mitosis is a type of cell division that gives rise to daughter cells that have the exact number of chromosomes as that of the parent cell. As a result this division is used for asexual reproduction, growth, repair and development.

• DNA replication occurs during S-phase of interphase - C) Mitosis and Meiosis.

Explanation - The replication of DNA during S-phase of interphase is an event that occurs at the beginning of both mitosis as well as meiosis. During the S phase of interphase, the genetic material doubles in order to prepare the cell for any kind of cellular division.

• The formation of a cleavage furrow marks the end of telophase - C) Mitosis and Meiosis

Explanation - The cleavage furrow is like a contractile ring that gradually proceeds inwards and drives the process of cytokinesis which is the division of cytoplasm. Therefore this must whenever cytokinesis occurs. And cytokinesis occurs in both mitosis and meiosis. As a result the right answer is C.

• Separation of homologous chromosomes occurs during anaphase - A) Meiosis.

Explanation - The separation of homologous chromosomes occurs during anaphase of meiosis and this is an unique event that occurs only during meiosis. As a result of this process, the chromosome number gets halved in each of the daughter cells that are formed.

• Separation of sister chromatids occur during anaphase - B) Mitosis.

Explanation - This is characteristic of mitosis. As a result of the separation of the sister chromatids (and not the homologous chromosomes), the number of chromosomes in the daughter cells are maintained the same as that of the parent cell.

• Karyokinesis or complete division of the nucleus occurs during telophase - C) Mitosis and Meiosis.

Explanation - Karyokinesis refers to the complete division of the nucleus and this leads to the formation of daughter nuclei. Therefore this is something that is essential to all kinds of cell division and hence the right answer is mitosis and meiosis.

• Cytokinesis or division of cytoplasm marks the end of the cell cycle - B) Mitosis.

Explanation - This is true for only mitosis and not meiosis. This is because, in case of meiosis, after the cytokinesis of meiosis 1 completes, meiosis 2 begins and meiosis 2 ends with another cytokinesis. But in case of mitosis, cytokinesis occurs only once and it marks the end of the cell cycle altogether.
