Quiz Preview

  • 2. 

    Mitosis produces

    • 2 genetically identical cells

    • 2 genetically different cells

    • 4 genetically identical cells

    • 4 genetically different cells.

    Correct Answer
    A. 2 genetically identical cells
    Explanation
    Mitosis is a type of cell division that results in the production of two genetically identical daughter cells. During mitosis, the genetic material of the parent cell is replicated and evenly distributed to the two daughter cells. This ensures that each daughter cell receives an exact copy of the genetic information, resulting in two cells that are genetically identical to each other and to the parent cell.

    Genetic variation is essential for species to ________

    Correct Answer
    evolve
    Explanation
    Genetic variation is essential for species to evolve because it allows for the introduction of new traits and characteristics into a population. This variation arises from genetic mutations, recombination, and gene flow, which can lead to individuals with different genetic makeups. Through natural selection, advantageous traits are favored, increasing the chances of survival and reproduction for those individuals. Over time, this process leads to the accumulation of beneficial genetic changes in the population, resulting in the evolution of new species or the adaptation of existing ones to their changing environment.

    Rate this question:

  • 4. 

    An organism would use ______ for sexual reproduction.

    • Mitosis

    • Meiosis

    Correct Answer
    A. Meiosis
    Explanation
    An organism would use meiosis for sexual reproduction because meiosis is a type of cell division that results in the formation of gametes (sex cells) with half the number of chromosomes as the parent cell. This process is necessary for sexual reproduction as it allows for the combination of genetic material from two parent organisms, resulting in genetic diversity in the offspring. Mitosis, on the other hand, is a type of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell, and is typically involved in growth, repair, and asexual reproduction.

    Rate this question:

  • 5. 

    The cell cycle is made up of

    • Mitosis and meiosis

    • Before and after

    • Interphase, mitosis, and cytokinesis.

    • G1 and G2

    Correct Answer
    A. Interphase, mitosis, and cytokinesis.
    Explanation
    The correct answer is interphase, mitosis, and cytokinesis. The cell cycle consists of three main phases: interphase, mitosis, and cytokinesis. Interphase is the longest phase where the cell grows and prepares for division. Mitosis is the phase where the cell's nucleus divides into two identical daughter nuclei. Cytokinesis is the final phase where the cytoplasm divides, resulting in two separate daughter cells. G1 and G2 are subphases within interphase and are not the complete cell cycle.

    What do two rounds of division in meiosis ensure?

    • That the daughter cells are diploid

    • That the daughter cells are haploid.

    • That the cells are genetically identical

    Correct Answer
    A. That the daughter cells are haploid.
    Explanation
    Two rounds of division in meiosis ensure that the daughter cells are haploid. Meiosis is a type of cell division that occurs in sexually reproducing organisms, and it involves two rounds of division. The purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes as the parent cell. During the first round of division (meiosis I), the homologous chromosomes separate, resulting in two haploid cells. Then, during the second round of division (meiosis II), the sister chromatids separate, resulting in four haploid daughter cells. Therefore, the correct answer is that the daughter cells are haploid.

  • 7. 

    An organism would use ______ for Asexual reproduction.

    • Mitosis

    • Meiosis

    • Option 3

    • Option 4

    Correct Answer
    A. Mitosis
    Explanation
    An organism would use mitosis for asexual reproduction because mitosis is the process by which a single cell divides into two identical daughter cells. This type of reproduction does not involve the fusion of gametes or the mixing of genetic material, resulting in offspring that are genetically identical to the parent. Mitosis is a common form of reproduction in single-celled organisms, as well as in some multicellular organisms, such as plants and animals that reproduce through budding or regeneration.

  • 8. 

    The purpose of mitosis is 

    • To create new gametes (sex cells)/

    • To create new somatic cells (body cells).

    • To drive biology students crazy.

    • Option 4

    Correct Answer
    A. To create new somatic cells (body cells).
    Explanation
    Mitosis is the process of cell division in which a single cell divides into two identical daughter cells. The purpose of mitosis is to create new somatic cells, also known as body cells. These cells are responsible for the growth, repair, and maintenance of the body. Gametes, on the other hand, are produced through a different process called meiosis. Therefore, the correct answer is to create new somatic cells (body cells).

    Meiosis produces

    • 2 genetically identical cells

    • 2 genetically different cells

    • 4 genetically identical cells

    • 4 genetically different cells.

    Correct Answer
    A. 4 genetically different cells.
    Explanation
    Meiosis is a type of cell division that occurs in reproductive cells to produce gametes (sperm and egg cells). During meiosis, the cell undergoes two rounds of division, resulting in four daughter cells. These daughter cells are genetically different from each other and from the parent cell due to a process called recombination or crossing over. This genetic diversity is crucial for sexual reproduction as it allows for the mixing and shuffling of genetic material from two parent organisms, increasing the variability of offspring. Therefore, the correct answer is 4 genetically different cells.

    Rate this question:

  • 10. 

    List the two main ways that genetic variation is caused in meiosis.  

  • 11. 

    Fully explain crossing over.

  • 12.

  • 13. 

    Read the last two paragraphs and explain why genetic diversity is so important for life.
