    In what phase of mitosis do chromatid pairs line up in the center of the cell?

    • A. prophase

    • B. metaphase

    • C. anaphase

    Correct Answer
    A. B. metaphase
    Explanation
    During metaphase, the chromatid pairs line up in the center of the cell. This phase occurs after prophase, where the chromosomes condense, and before anaphase, where the chromatids separate and move towards opposite poles of the cell. In metaphase, the spindle fibers attach to the centromeres of the chromatids, aligning them along the equator of the cell. This alignment ensures that each daughter cell receives an equal number of chromosomes during cell division.

    What important events occur during interphase of the cell cycle?

    • A. cytoplasm is divided equally among the daughter cells

    • B. cell growth, production of new organelles, DNA replication

    • C. synapsis occurs, homologous chromosomes pair to form tetrads

    • D. the chromosomes line up along the center of the cell

    Correct Answer
    A. B. cell growth, production of new organelles, DNA replication
    Explanation
    During interphase of the cell cycle, cell growth occurs, which involves an increase in size and volume of the cell. Additionally, new organelles are produced to support the functions of the cell. DNA replication takes place during interphase, where the cell's genetic material is duplicated in preparation for cell division. These events are crucial for the cell to ensure that it is ready for the next phase of the cell cycle.

  • 5. 

    A cell in interphase is sometimes said to be resting. This is misleading. Why?

    • A. Interphase cells are actively dividing

    • B. Interphase cells are synthesizing RNA, proteins and growing in size

    Correct Answer
    A. B. Interphase cells are synthesizing RNA, proteins and growing in size
    Explanation
    The statement "A cell in interphase is sometimes said to be resting" is misleading because interphase cells are not actually at rest. During interphase, cells are actively synthesizing RNA, proteins, and growing in size. This is a crucial period in the cell cycle where various cellular processes are occurring in preparation for cell division. Therefore, the term "resting" is not accurate to describe interphase cells.

    During which of the following stages of mitosis do sister chromatids line up along the center of the dividing cell?

    • A. prophase

    • B. metaphase

    • C. anaphase

    • D. telophase

    Correct Answer
    A. B. metaphase
    Explanation
    During metaphase, sister chromatids line up along the center of the dividing cell. This is the stage where the spindle fibers attach to the centromeres of the sister chromatids and align them along the metaphase plate, which is equidistant between the two poles of the cell. This alignment ensures that each daughter cell will receive an equal number of chromosomes during cell division.

    The formation of new somatic cells in the human body is the direct result of which of the following processes?

    • A. meiosis

    • B. mitosis

    • C. Aerobic respiration

    • D.anaerobic respiration

    Correct Answer
    A. B. mitosis
    Explanation
    Mitosis is the correct answer because it is the process by which new somatic cells are formed in the human body. During mitosis, a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. This process is responsible for growth, repair, and maintenance of body tissues. Meiosis, on the other hand, is the process of cell division that produces gametes (sperm and eggs) for sexual reproduction. Aerobic and anaerobic respiration are metabolic processes that generate energy in cells, but they are not directly involved in the formation of new somatic cells.

    Why is mitosis important for asexual reproduction?

    • A. it allows for crossing over to occur

    • B. it allows for genetic reproduction

    • C. it halves the chromosome number

    • D. it keeps the chromosome number constant

    Correct Answer
    A. D. it keeps the chromosome number constant
    Explanation
    Mitosis is important for asexual reproduction because it ensures that the chromosome number remains constant. During mitosis, the parent cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. This allows for the genetic information to be passed on to the offspring without any changes in the chromosome number. By maintaining the same chromosome number, mitosis helps to preserve the genetic integrity and stability of the species during asexual reproduction.
