Questions and Answers
  • 1. 

    The ________ has a lining that secretes mucus and  sperm are deposited here.

    Explanation
    The lining of the vagina secretes mucus and is the site where sperm are deposited.

    Rate this question:

  • 2. 

    Reproduction ensures the survival of a species and ensures that identical genes are passed on to offsprings.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Reproduction ensures the survival of a species by creating new individuals, but it does not necessarily ensure that identical genes are passed on to offspring. In sexual reproduction, offspring inherit a combination of genes from both parents, resulting in genetic variation. This variation is important for the adaptation and evolution of a species. Therefore, the statement is false.

  • 3. 

    The release of ova from the ovary is

    • A.

      Conception

    • B.

      Copulation

    • C.

      Ovulation

    • D.

      Implantation

    Correct Answer
    C. Ovulation
    Explanation
    Ovulation refers to the release of an egg from the ovary. This is a crucial process in the female reproductive system, where a mature egg is released and becomes available for fertilization by sperm. Ovulation occurs approximately once a month during a woman's menstrual cycle. It is an essential step in the process of conception, as fertilization can only occur if the egg is released and meets with sperm. Therefore, ovulation is the correct answer in this context.

    Rate this question:

  • 4. 

    A gamete is a cell

    • A.

      Formed by fertilization

    • B.

      Produced by mitosis

    • C.

      With the haploid number of chromosomes

    • D.

      With the diploid number of chromosomes

    Correct Answer
    C. With the haploid number of chromosomes
    Explanation
    A gamete is a cell that is formed by fertilization and it carries half the number of chromosomes as compared to the other cells in the organism. This is known as the haploid number of chromosomes. Gametes are involved in sexual reproduction and when they combine during fertilization, they restore the diploid number of chromosomes in the resulting zygote. Therefore, the correct answer is "with the haploid number of chromosomes".

    Rate this question:

  • 5. 

    Which part produces sperm cells?

    • A.

      A

    • B.

      B

    • C.

      C

    • D.

      D

    Correct Answer
    D. D
    Explanation
    Part D produces sperm cells.

    Rate this question:

  • 6. 

    What is the name of the structure labeled B on the diagram?

    • A.

      Urethra

    • B.

      Sperm duct

    • C.

      Ureter

    • D.

      Seminal vesical

    Correct Answer
    A. Urethra
    Explanation
    The structure labeled B on the diagram is the urethra. The urethra is a tube that carries urine from the bladder to the outside of the body in both males and females. In males, it also serves as a passageway for semen during ejaculation.

    Rate this question:

  • 7. 

    Which of the following is not an advantage of asexual reproduction?

    • A.

      Genetic variation introduced

    • B.

      Successful characteristics are passed on to off springs

    • C.

      Often results in large numbers of off springs

    • D.

      No need to find a mate

    Correct Answer
    A. Genetic variation introduced
    Explanation
    The correct answer is "Genetic variation introduced." Asexual reproduction does not involve the fusion of gametes or the exchange of genetic material, so there is no introduction of genetic variation. Asexual reproduction produces offspring that are genetically identical to the parent, which can be advantageous in a stable environment but limits the ability to adapt to changing conditions.

    Rate this question:

  • 8. 

    How long does the ovum live until it is no longer viable?

    • A.

      12 hours

    • B.

      18 hours

    • C.

      24 hours

    • D.

      48 hours

    Correct Answer
    D. 48 hours
    Explanation
    The ovum, or egg, has a lifespan of approximately 48 hours before it is no longer viable. This means that after it is released from the ovary during ovulation, it can be fertilized by sperm within this time frame. If fertilization does not occur within 48 hours, the ovum will begin to deteriorate and will not be able to result in a pregnancy.

    Rate this question:

  • 9. 

    Cancer of the ovary is not common, but it causes more deaths than other female reproductive cancers.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Cancer of the ovary is indeed not common, but it is responsible for more deaths than other female reproductive cancers. This means that even though it may occur less frequently, it has a higher mortality rate compared to other types of reproductive cancers in women. Therefore, the statement is true.
