    AS you become an adult the cells in your body _______.

    • A.

      Keep dividing

    • B.

      Grow bigger

    Correct Answer
    A. Keep dividing
    Explanation
    As you become an adult, the cells in your body continue to divide. This process is known as cell division and is essential for growth, repair, and maintenance of the body. Cell division allows for the production of new cells to replace old or damaged ones, ensuring the proper functioning of tissues and organs. Therefore, the statement "Keep dividing" accurately describes the behavior of cells in the adult body.

    Rate this question:

  • 3. 

    How do cells share genetic material?

    • A.

      They divide.

    • B.

      They become specialized.

    Correct Answer
    A. They divide.
    Explanation
    Cells share genetic material through the process of cell division. During cell division, the genetic material, which is stored in the form of DNA, is replicated and then distributed equally between the two daughter cells. This ensures that each cell receives a complete set of genetic instructions necessary for its functioning. Cell division plays a crucial role in growth, development, and reproduction, allowing genetic material to be passed on to new cells and organisms. By dividing, cells are able to share their genetic material and propagate the genetic information to future generations.

    Rate this question:

  • 4. 

    The cell cycle begins with _______.

    • A.

      Cytokinesis

    • B.

      Interphase

    Correct Answer
    B. Interphase
    Explanation
    The cell cycle begins with interphase. Interphase is the longest phase of the cell cycle and is divided into three stages: G1 phase, S phase, and G2 phase. During interphase, the cell grows, carries out normal cell functions, and replicates its DNA in preparation for cell division. Cytokinesis, on the other hand, is the final stage of the cell cycle and occurs after mitosis or meiosis when the cytoplasm divides, resulting in two daughter cells. Therefore, interphase is the correct answer as it marks the start of the cell cycle.

    Rate this question:

  • 5. 

    Which of the following happens during mitosis?

    • A.

      The chromosomes line up in the center of the cell.

    • B.

      A cell completes one entire cell cycle.

    Correct Answer
    A. The chromosomes line up in the center of the cell.
    Explanation
    During mitosis, the chromosomes line up in the center of the cell. This is a crucial step known as metaphase, where the spindle fibers attach to the centromere of each chromosome, aligning them along the equatorial plane of the cell. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division. The chromosomes will then be separated and pulled towards opposite poles of the cell during anaphase. The fact that a cell completes one entire cell cycle is not specific to mitosis and can occur during other phases of the cell cycle as well.

    Rate this question:

  • 6. 

    Threadlike DNA material that binds together to create a rod-shaped chromosome.

    • A.

      Chromatin

    • B.

      Centromere

    Correct Answer
    A. Chromatin
    Explanation
    Chromatin is the correct answer because it refers to the threadlike DNA material that binds together to create a rod-shaped chromosome. Chromatin is composed of DNA, histone proteins, and other structural proteins, and it undergoes condensation and coiling to form chromosomes during cell division. The term "centromere" refers to the region of a chromosome where the two sister chromatids are attached, and it is not related to the threadlike DNA material that forms chromosomes.

    Rate this question:

  • 7. 

    _______ is the longest phase of the cell cycle. During this time, the cell's DNA is copied.

    • A.

      Interphase

    • B.

      Prophase

    Correct Answer
    A. Interphase
    Explanation
    Interphase is the longest phase of the cell cycle because it encompasses the period between cell divisions. During this phase, the cell prepares for division by undergoing various processes, including DNA replication. This ensures that each daughter cell receives a complete set of genetic material. Interphase consists of three sub-phases: G1 phase, S phase, and G2 phase. In the S phase, DNA replication occurs, where the cell's DNA is copied to prepare for cell division. Therefore, Interphase is the correct answer as it accurately describes the phase in which DNA replication takes place.

    Rate this question:

  • 8. 

    During this phase, the X-shaped chromatids, line up in the center of the cell.

    • A.

      Metaphase

    • B.

      Cytokinesis

    Correct Answer
    A. Metaphase
    Explanation
    During metaphase, the X-shaped chromatids, which are duplicated chromosomes, align themselves in the center of the cell. This alignment is crucial for the equal distribution of genetic material to the daughter cells during cell division. The chromosomes are attached to spindle fibers, which help move and position them at the metaphase plate. Once the chromosomes are properly aligned, the cell can proceed to the next phase of cell division. Cytokinesis, on the other hand, is the final stage of cell division where the cytoplasm divides to form two separate daughter cells.

      Ribosomes

    Correct Answer
    B. Ribosomes
    Explanation
    Ribosomes are responsible for protein synthesis in the cell. They are like a protein factory because they create proteins that are necessary for the cell to build up organelles. Ribosomes read the genetic information from mRNA and use it to assemble amino acids into proteins. These proteins are essential for various cellular processes and structures, including the formation of organelles. Therefore, ribosomes play a crucial role in protein production and contribute to the cell's ability to build and maintain its organelles.
