    A woman releases certain hormones when she is pregnant. These help to prevent another menstrual cycle. What are they?

    • Estrogen and progesterone

    • FSH and LH

    • LH and GnRH

    • Estrogen and LH

    Correct Answer
    A. Estrogen and progesterone
    Explanation
    During pregnancy, the woman's body releases estrogen and progesterone hormones. These hormones play a crucial role in maintaining the pregnancy by inhibiting the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are responsible for initiating another menstrual cycle. Estrogen and progesterone work together to create a hormonal environment that supports the development and sustenance of the pregnancy, preventing the shedding of the uterine lining and the occurrence of menstruation.

    • Ectopic pregnancy

    • Hayflick pregnancy

    • Menstural cycle

    Correct Answer
    A. Ectopic pregnancy
    Explanation
    An ectopic pregnancy occurs when a fertilized egg implants and grows outside the uterus, typically in the fallopian tube. This is a dangerous condition as the embryo cannot develop properly and can cause severe complications for the mother. It requires immediate medical attention and intervention to prevent further harm.

    Pregnancy causes the __________, the lining of the uterus, to grow.

    • Endometrium

    • Corpus Luteum

    • Egg Folice

    • Fallopian Tubes

    Correct Answer
    A. Endometrium
    Explanation
    During pregnancy, the endometrium, which is the lining of the uterus, undergoes significant growth. This is because the endometrium plays a crucial role in supporting the implantation and development of the fertilized egg. As pregnancy progresses, the endometrium continues to thicken and develop blood vessels to provide nourishment to the growing fetus. Therefore, the correct answer is endometrium.

  • 6. 

    Where does fertilization occur?

    • Endometrium

    • Corpus Luteum

    • Fallopian Tubes

    • Egg Folice

    Correct Answer
    A. Fallopian Tubes
    Explanation
    Fertilization occurs in the fallopian tubes. After ovulation, the egg is released from the ovary and travels through the fallopian tube. If sperm are present in the fallopian tube, they can fertilize the egg, resulting in pregnancy. The fallopian tubes provide the ideal environment for fertilization to occur, with their ciliated lining and muscular contractions helping to move the egg and sperm towards each other. Once fertilization occurs in the fallopian tube, the fertilized egg then travels to the uterus for implantation.

    Rate this question:

  • 7. 

    GnRH causes the pituitary gland to produce which hormones...

    • Prolactin and Oxytocin

    • LH and FSH

    • Prolacin and LH

    • Oxtocin and LH

    Correct Answer
    A. LH and FSH
    Explanation
    GnRH (Gonadotropin-releasing hormone) stimulates the pituitary gland to produce LH (luteinizing hormone) and FSH (follicle-stimulating hormone). These hormones are essential for the regulation of the reproductive system. LH triggers ovulation and stimulates the production of testosterone in males, while FSH is responsible for the development of ovarian follicles in females and sperm production in males. Therefore, the correct answer is LH and FSH.

    What is the function of an acrosome?

    • Allows sperm to digest its way to the cell membrane

    • Allows sperm to get rid of the acidity

    • Allows sperm to feed on fructose

    Correct Answer
    A. Allows sperm to digest its way to the cell membrane
    Explanation
    The function of an acrosome is to allow sperm to digest its way to the cell membrane. The acrosome is a structure located at the head of the sperm and contains enzymes that help the sperm penetrate and fertilize the egg. These enzymes break down the outer layer of the egg, allowing the sperm to reach the cell membrane and fuse with it. This process is essential for successful fertilization to occur.

    Rate this question:

  • 9. 

    What is the purpose of the fertilization membrane?

    • Allows sperm easy access to the egg

    • Prevents more than one sperm from fertilizing an egg

    • Protects unfertilized eggs from accidental fertilization

    Correct Answer
    A. Prevents more than one sperm from fertilizing an egg
    Explanation
    The fertilization membrane serves the purpose of preventing more than one sperm from fertilizing an egg. This is important because if multiple sperm were to fertilize the egg, it would result in an abnormal number of chromosomes and genetic material, leading to developmental issues in the resulting embryo. By forming a barrier, the fertilization membrane ensures that only one sperm can successfully penetrate and fertilize the egg, ensuring the correct number of chromosomes for normal development.

    Rate this question:

  • 10. 

    What is the corpus luteum made of?

    • Leftover embryonic cells

    • Leftover follicular cells

    • Leftover follupian cells

    • Live embryonic cells

    Correct Answer
    A. Leftover follicular cells
    Explanation
    The corpus luteum is made of leftover follicular cells. After the release of an egg from the ovary, the empty follicle undergoes changes and forms the corpus luteum. This structure produces hormones, primarily progesterone, which is important for preparing the uterus for pregnancy. If fertilization does not occur, the corpus luteum degenerates, leading to a decrease in hormone production and the start of a new menstrual cycle.

    If you believe in the Genetic Clock theory, you believe that:

    • Cells can only be divided so many times

    • Antioxidants will help you live longer

    • Reducing calories creates better body function

    Correct Answer
    A. Cells can only be divided so many times
    Explanation
    The correct answer is that if you believe in the Genetic Clock theory, you believe that cells can only be divided so many times. This theory suggests that cells have a limited number of divisions before they reach a point of senescence or cell death. This concept is often associated with the aging process, as it implies that our cells have a predetermined lifespan.

    What is pseudohermaphroditism?

    • A mismatch between chromosome sex and either internal sex organs, external sex organs, or psyche

    • Individual born with working male and female parts

    • Individual first born as male and then born as female

    • Individual first born as female and then born as male

    Correct Answer
    A. A mismatch between chromosome sex and either internal sex organs, external sex organs, or psyche
    Explanation
    Pseudohermaphroditism refers to a condition where there is a mismatch between the individual's chromosome sex and their internal or external sex organs, or even their psyche. This means that the individual may have the chromosomes of one sex, but the physical characteristics or gender identity of another sex. It can manifest in various ways, such as an individual being born with both male and female reproductive organs or being born with one set of reproductive organs and later transitioning to the other sex.

    • Oxytocin; prolactin

    • Oxytocin; GnRH

    • Residual sperm; alkaline fluid

    • Residual sperm; prolactin

    Correct Answer
    A. Residual sperm; alkaline fluid
    Explanation
    The Bulbourethral Glands, also known as Cowper's Gland, produce two products: residual sperm and alkaline fluid. The residual sperm refers to the small amount of sperm that may still be present in the urethra after ejaculation. The alkaline fluid helps to neutralize the acidity of the urethra and vagina, providing a more favorable environment for sperm survival and motility. This combination of residual sperm and alkaline fluid helps to enhance the chances of successful fertilization.

  • 20. 

    How do fertility drugs cause the release of multiple eggs?

    • LH

    • GnRH

    • FSH

    Correct Answer
    A. FSH
    Explanation
    Fertility drugs stimulate the release of multiple eggs by increasing the levels of follicle-stimulating hormone (FSH) in the body. FSH is responsible for the growth and development of follicles in the ovaries. When the levels of FSH are elevated, it promotes the maturation of multiple follicles, each containing an egg. This increases the chances of releasing multiple eggs during ovulation, thereby increasing the chances of pregnancy.

    What is fragmentation?

    • Cells split into two identical cells

    • Production of offspring from unfertilized eggs

    • Pieces grow off and grow into new individuals

    • Genetically identical individuals grow off other individuals

    Correct Answer
    A. Pieces grow off and grow into new individuals
    Explanation
    Fragmentation is a form of asexual reproduction where pieces of an organism break off and grow into new individuals. This process allows for the regeneration of lost body parts and the production of genetically identical offspring. It is a common method of reproduction in certain organisms such as flatworms and starfish.

    How do conjoined twins form?

    • One cells in the blastopore splits

    • Cells in blastopore seperate incompletely

    • Cells in the blastopore fuse

    Correct Answer
    A. Cells in blastopore seperate incompletely
    Explanation
    Conjoined twins form when cells in the blastopore separate incompletely. During embryonic development, the blastopore is a small depression that eventually develops into the digestive and reproductive systems. If the cells in the blastopore do not fully separate, it can result in the formation of conjoined twins, where two individuals are physically connected to each other. This incomplete separation can occur due to various factors, such as genetic mutations or environmental influences, leading to the unique condition of conjoined twins.

    Some factors in the environment can determine the sex of a given organism. Which of the following is NOT a factor...?

    • Toxins

    • Sunlight

    • Temperature

    • Availability of the other sex

    Correct Answer
    A. Sunlight
    Explanation
    Sunlight is not a factor that determines the sex of an organism. While factors such as toxins, temperature, and the availability of the other sex can influence the sex of an organism, sunlight does not play a direct role in determining sex. Sunlight is important for various biological processes, such as photosynthesis, but it does not have a direct impact on the sexual development or determination of an organism.

    What is the purpose of prostoglandins?

    • To provide food for the sperm

    • To produce contractions to let the sperm in

    • To reduce the acidity of the vagina

    • To create sensations of pleasure

    Correct Answer
    A. To produce contractions to let the sperm in
    Explanation
    Prostaglandins serve the purpose of producing contractions to facilitate the entry of sperm. These chemical substances are released by the male prostate gland and play a crucial role in the reproductive process. The contractions caused by prostaglandins help propel the sperm through the cervix and into the uterus, increasing the chances of fertilization. Therefore, the purpose of prostaglandins is to aid in the transportation and successful entry of sperm into the female reproductive system.

    This theory of aging suggests that the accumulation of mutations over a lifetime causes an organism's death:

    • Genetic Clock Hypothesis

    • Evolutionary Theory of Aging

    • Free Radical Theory of Aging

    • Fry's Theory of Agin

    Correct Answer
    A. Evolutionary Theory of Aging
    Explanation
    The evolutionary theory of aging suggests that the accumulation of mutations over a lifetime causes an organism's death. This theory proposes that natural selection favors genes that are beneficial for survival and reproduction early in life, but may have negative effects later in life. As a result, mutations that cause aging-related decline and death may accumulate in a population over time, as they have less impact on reproductive success. This theory explains why aging is a universal phenomenon observed in most organisms.

    Rate this question:

    Which is NOT a function of the prostate gland?

    • Produces alkaline fluid to balance acidity of the vagina

    • Produce prostoglandins

    • Produce enzymes that clot and declot sperm

    • Produce sugar for the sperm to feed on

    Correct Answer
    A. Produce sugar for the sperm to feed on
    Explanation
    The prostate gland is responsible for producing various substances that support the function and survival of sperm. It produces alkaline fluid to balance the acidity of the vagina, which helps to protect and nourish the sperm. It also produces prostaglandins, which are involved in sperm motility and fertilization. Additionally, the prostate gland produces enzymes that clot and declot sperm, aiding in their movement through the reproductive tract. However, it does not produce sugar for the sperm to feed on. Sperm obtain energy from fructose, which is produced by the seminal vesicles.

    A body builder takes anabolic steroids. He then notices a decrease in sperm production. Why?

    • Decreased levels of testosterone, causing a decrease in GnRH and therefore LH and FSH

    • Increased levels of testosterone, causing a decrease in GnRH and therefore LH and FSH

    • Interference with LH,, causing a decrease in GnRH

    • No effect

    Correct Answer
    A. Decreased levels of testosterone, causing a decrease in GnRH and therefore LH and FSH
    Explanation
    When a bodybuilder takes anabolic steroids, it increases the levels of testosterone in the body. This excess testosterone can lead to a negative feedback mechanism where the body senses high levels of testosterone and reduces the production of gonadotropin-releasing hormone (GnRH). GnRH is responsible for stimulating the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for sperm production. Therefore, decreased levels of testosterone caused by the use of anabolic steroids can result in a decrease in GnRH, LH, and FSH, leading to a decrease in sperm production.

    If you were a barnacle that could not connect directly connect with a sexual partner, how would you want to distribute your gametes?

    • Ovipary

    • Broadcast spawning

    • Internal fertilization

    • Self fertilization

    Correct Answer
    A. Broadcast spawning
    Explanation
    Broadcast spawning would be the preferred method of distributing gametes for a barnacle that cannot directly connect with a sexual partner. This method involves releasing large quantities of gametes into the surrounding water, increasing the chances of fertilization. It allows for the gametes to be dispersed over a larger area, increasing the likelihood of encountering a compatible partner and maximizing the chances of successful reproduction.

    What is budding?

    • Cells split into two identical cells

    • Genetically identical individuals grow off other individuals

    • Pieces grow off and grow into new individuals

    • Production of offspring from unfertilized eggs

    Correct Answer
    A. Genetically identical individuals grow off other individuals
    Explanation
    Budding is a form of asexual reproduction where genetically identical individuals grow off other individuals. In this process, a small outgrowth or bud forms on the parent organism, which eventually detaches and develops into a new individual. This new individual is genetically identical to the parent and carries the same genetic information. This method of reproduction is commonly observed in organisms such as yeast, hydra, and some plants.

    What does the Hayflick Limit apply to?

    • Chromosomes

    • Cells

    • Telomeres

    Correct Answer
    A. Cells
    Explanation
    The Hayflick Limit refers to the maximum number of times that cells can divide before they reach senescence or cell death. This limit applies to cells in general, regardless of their specific characteristics such as chromosomes or telomeres. As cells divide, the telomeres, which are protective caps at the ends of chromosomes, gradually shorten. When the telomeres become critically short, cells can no longer divide and enter a state of senescence. Therefore, while chromosomes and telomeres are involved in the process, the Hayflick Limit is primarily concerned with the division potential of cells.

    Humans develop inside a female for nine months. They get an umbilical cord for nutrition. What way of handling a fertileized egg does this exemplify?

    • Ovipary

    • Ovovivipary

    • Vivipary

    • Multiple births

    Correct Answer
    A. Vivipary
    Explanation
    This exemplifies vivipary, which is the reproductive method where offspring develop inside the body of the parent and receive nutrition through a placenta or umbilical cord. In this case, the human fetus develops inside the female's uterus for nine months and receives nutrients through the umbilical cord. This is different from ovipary, where eggs are laid outside the body, and ovovivipary, where eggs hatch inside the body but do not receive nutrients from the parent. Multiple births refers to the situation where a female gives birth to more than one offspring at a time.

    Where is estrogen produced in a pregnant woman?

    • Fallopian Tubes

    • Egg Folice

    • Corpus Luteum

    • Endometrium

    Correct Answer
    A. Endometrium
    Explanation
    During pregnancy, estrogen is primarily produced by the placenta. However, before the placenta forms, the corpus luteum in the ovary is responsible for producing estrogen. The fallopian tubes and egg follicles do not produce estrogen during pregnancy. The endometrium, on the other hand, is the lining of the uterus where implantation of the fertilized egg takes place, and it plays a crucial role in supporting pregnancy by producing estrogen.
