Questions and Answers
  • 1. 

    Does Stem Cell Research lead to abortion?

    • A.

      True.

    • B.

      False.

    Correct Answer
    B. False.
    Explanation
    Stem Cells are extracted from the mother 6 days after fertilization, during the blastocyst stage of development. At this point, the cells have yet to attatch to the uterus and have to go through 19 other steps before fetal development begins.

    Rate this question:

  • 2. 

    What are Stem Cells?

    • A.

      Cells that can become any type of cell. Ex: blood, muscle, skin cells.

    • B.

      Cells that can renew themselves continuously.

    • C.

      Cells that can go from being (for example) a blood cell to a neuron.

    • D.

      All of the above.

    • E.

      None of the above.

    Correct Answer
    D. All of the above.
    Explanation
    Stem cells are cells that have the unique ability to develop into various types of cells in the body. They can become any type of cell (blood, muscle, skin cells), renew themselves continuously, and can differentiate into different cell types (for example, a blood cell can transform into a neuron). Therefore, all the options provided accurately describe stem cells.

    Rate this question:

  • 3. 

    Where can Stem Cells come from?

    • A.

      Umbilical cord blood.

    • B.

      Plant stems.

    • C.

      Unborn babies.

    Correct Answer
    A. Umbilical cord blood.
    Explanation
    The word "stem" has nothing to do with plant stems. Also, refer to the explanation for question 1 to see why answer choice C is incorrect.

    Rate this question:

  • 4. 

    How many known stem cells types are there?

    • A.

      1

    • B.

      3

    • C.

      5

    • D.

      0

    • E.

      9

    Correct Answer
    B. 3
    Explanation
    There are three known types of stem cells: Embryonic Stem Cells, Adult Stem Cells, and Umbilical cord Stem Cells.

    Rate this question:

  • 5. 

    What are Stem Cells used for?

    • A.

      Replacing diseased cells in sick patients.

    • B.

      Growing into a new organ that a patient needs.

    • C.

      Making a clone of you in case you die.

    • D.

      Only A and B.

    • E.

      All of the above.

    Correct Answer
    D. Only A and B.
    Explanation
    Stem cells are used for replacing diseased cells in sick patients and growing into a new organ that a patient needs. These cells have the ability to differentiate into different cell types and can be used in regenerative medicine to treat various diseases and injuries. They hold great potential for repairing and replacing damaged tissues and organs in the human body. The option "Only A and B" correctly identifies the uses of stem cells in medical applications, excluding the unrelated option of making a clone and the all-encompassing option of "All of the above."

    Rate this question:

  • 6. 

    Cloning is involved in Stem Cell Research.

    • A.

      True.

    • B.

      False.

    Correct Answer
    A. True.
    Explanation
    Though many of us think of cloning as human replication, cloning in the scientific world means cell division. Cell division is when cells replicate, and occurs on a daily basis in all organisms.

    Rate this question:

  • 7. 

    What is a stem cell line?

    • A.

      Stem Cells lined up in a row.

    • B.

      Stem Cells in the lineage.

    • C.

      A population of Stem Cells grown by scientists.

    • D.

      A Stem Cell broken down, with it's contents placed in a line.

    Correct Answer
    C. A population of Stem Cells grown by scientists.
    Explanation
    Definition from http://www.kumc.edu/stemcell/glossary.html: Stem cells that have been growing in cell culture for six or more months without becoming specialized and appear genetically normal.

    Rate this question:

  • 8. 

    What are somatic cells?

    • A.

      Sperm Cells.

    • B.

      Non-sex cells. Ex: skin cell.

    • C.

      Egg Cell.

    • D.

      Stomach cells.

    • E.

      Cells found in the stoma.

    Correct Answer
    B. Non-sex cells. Ex: skin cell.
    Explanation
    Somatic cells are non-sex cells, meaning they are not involved in sexual reproduction. Examples of somatic cells include skin cells, muscle cells, and nerve cells. These cells make up the majority of the body and perform various functions necessary for the organism's survival and growth. In contrast, sperm cells and egg cells are involved in sexual reproduction and are not considered somatic cells.

    Rate this question:

  • 9. 

    What is an Adult Stem Cell?

    • A.

      A cell extracted from mature tissue.

    • B.

      A cell extracted only from children.

    • C.

      A cell extracted only from adults.

    • D.

      Both A and C.

    • E.

      None of the above.

    Correct Answer
    A. A cell extracted from mature tissue.
    Explanation
    Do not let the term "adult" confuse you. Mature tissue is found in any human after birth. Tissues are only not "adult" while still in development, that is, in the embryonic stage.

    Rate this question:

  • 10. 

    How many stem cell lines does the United States currently have?

    • A.

      100

    • B.

      9

    • C.

      65

    • D.

      43

    • E.

      2

    Correct Answer
    C. 65
    Explanation
    The United States currently has 65 stem cell lines.
