    The pituitary gland of both males and females produced FSH and LH but the cell receptors are different

    • True

    • False

    • Ture

    • Flase

    Correct Answer
    A. True
    Explanation
    The statement is true because the pituitary gland in both males and females produces follicle-stimulating hormone (FSH) and luteinizing hormone (LH). However, the cell receptors for these hormones differ between males and females. This difference in receptors allows FSH and LH to have different effects in males and females, contributing to the regulation of reproductive processes specific to each sex.

    What is the function of an acrosome?

    • Holding mitochondria

    • Containing enzymes that dissolve protective layers around the egg

    • Propels sperm

    • Protects sperm

    Correct Answer
    A. Containing enzymes that dissolve protective layers around the egg
    Explanation
    The acrosome is a structure found in the head of sperm cells. It contains enzymes that are responsible for dissolving the protective layers surrounding the egg during fertilization. This allows the sperm to penetrate and fertilize the egg. Therefore, the function of the acrosome is to facilitate the process of fertilization by breaking down the barriers around the egg.

    Rate this question:

  • 7. 

    After ovulation, the mature follicle becomes the corpus luteum

    • True

    • False

    Correct Answer
    A. True
    Explanation
    After ovulation, the mature follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum is responsible for producing hormones, primarily progesterone, which is crucial for preparing the uterus for possible implantation of a fertilized egg. If fertilization does not occur, the corpus luteum will gradually degenerate, leading to a decrease in hormone production and the start of a new menstrual cycle. Therefore, the statement "after ovulation, the mature follicle becomes the corpus luteum" is true.

    The egg must be fertilized in the upper 1/3 of the uterus

    • True

    • False

    • Blue

    • 26

    Correct Answer
    A. False
    Explanation
    The statement "The egg must be fertilized in the upper 1/3 of the uterus" is false. Fertilization of the egg typically occurs in the fallopian tubes, not in the uterus. After ovulation, the egg is released from the ovary and travels through the fallopian tube where it can be fertilized by sperm. Once fertilized, the egg then implants itself in the uterus for further development.

    Rate this question:

  • 11. 

    The characteristic/ gene that causes maleness is located in the         

    • Autosome

    • X chromosome

    • Y chromosome

    • Ribosome

    Correct Answer
    A. Y chromosome
    Explanation
    The Y chromosome is responsible for determining maleness in humans. It contains the SRY gene, which triggers the development of male characteristics during embryonic development. This gene instructs the gonads to develop into testes, which then produce testosterone and other male hormones. Without the presence of the Y chromosome and the SRY gene, an individual will develop female characteristics. Therefore, the Y chromosome is the correct answer as it carries the gene responsible for maleness.

    Sperm is produced the the seminiferous tubules of the testes, while eggs are produced by the germinal epithelium of the ovaries

    • True

    • False

    • Whats with all the ovaries?

    • No

    Correct Answer
    A. True
    Explanation
    The statement is true because sperm is indeed produced in the seminiferous tubules of the testes, while eggs (oocytes) are produced by the germinal epithelium of the ovaries. The testes are responsible for the production of male gametes (sperm), while the ovaries are responsible for the production of female gametes (eggs).

    In most mammals the testes must be descended outside of the body for sperm to be viable

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    In most mammals, the testes must be descended outside of the body for sperm to be viable. This is because the testes require a lower temperature than the body in order to produce healthy sperm. If the testes remain inside the body, the higher body temperature can damage the sperm and render them non-viable. Therefore, it is true that in most mammals, the testes need to be descended outside of the body for sperm to be viable.

    Rate this question:

  • 15. 

    Spermatids are a haploid

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Spermatids are indeed haploid cells. Haploid cells contain only one set of chromosomes, which is half the number found in diploid cells. In the process of spermatogenesis, spermatids are formed from spermatocytes through meiosis. During meiosis, the spermatocytes divide twice, resulting in the formation of four haploid spermatids. These spermatids then undergo further maturation to develop into sperm cells. Therefore, the statement "Spermatids are haploid" is correct.

  • 16. 

    Vas deferens connects the epididymis to the urethra

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The vas deferens is a tube that connects the epididymis, where sperm is stored, to the urethra. This allows for the transport of sperm from the testes to the urethra, where it can be ejaculated during sexual intercourse. Therefore, the statement that the vas deferens connects the epididymis to the urethra is true.

    Rate this question:

  • 17. 

    The sugar fructose in the seminal fluid provides the sperm nutrition, while pH buffers protect the sperm from acid

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that fructose, a type of sugar found in seminal fluid, provides nutrition to the sperm. This is important for their survival and energy production during fertilization. Additionally, pH buffers in the seminal fluid help protect the sperm from the acidic environment of the female reproductive tract, ensuring their viability and ability to reach the egg. Therefore, the statement is true.

    Castration or removal of the testes before puberty will interfere with development of secondary sex characteristics in males such as voice, muscle mass, and hairyness

    • True

    • False

    • Pass

    • That would hurt, amiright?

    Correct Answer
    A. True
    Explanation
    Castration or removal of the testes before puberty will indeed interfere with the development of secondary sex characteristics in males. The testes produce testosterone, which is responsible for the development of these characteristics such as deepening of the voice, increased muscle mass, and the growth of body hair. By removing the testes, the production of testosterone is significantly reduced, leading to a lack of development in these secondary sex characteristics.

    The egg ovulates under the influence of LH on about the 14th day of menstruation 

    • True

    • False

    • Eggs

    • Haha

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that LH (luteinizing hormone) is responsible for triggering ovulation, which is the release of an egg from the ovary. Ovulation typically occurs around the 14th day of the menstrual cycle, although this can vary slightly among individuals. Therefore, the statement that the egg ovulates under the influence of LH on about the 14th day of menstruation is true.

    Rate this question:

  • 20. 

    In days, it takes about how long for an ovum or egg to travel down the oviduct (Fallopian tubes)

    • 1

    • 1-2

    • 2-3

    • 4-5

    Correct Answer
    A. 2-3
    Explanation
    The correct answer is 2-3 days. After ovulation, the released egg travels down the oviduct or Fallopian tube towards the uterus. This journey takes approximately 2-3 days. During this time, the egg may be fertilized by sperm if intercourse occurs. If fertilization does not occur, the egg will disintegrate and be shed along with the uterine lining during menstruation.

    Rate this question:

  • 21. 

    Castration after puberty can reduce sex interest in males

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    Castration after puberty can reduce sex interest in males because the testicles produce testosterone, the primary male sex hormone. Removing the testicles through castration eliminates the main source of testosterone production, leading to a decrease in sexual desire and activity. This is because testosterone plays a crucial role in regulating libido and sexual function in males. Therefore, castration can effectively reduce sex interest in males.

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    Sperm is indeed produced by the seminiferous tubules of the testes, while eggs are produced by the germinal epithelium of the ovaries. This is a correct statement about the reproductive system in humans.

    Rate this question:

  • 23. 

    Follicles in the ovary rupture to release the egg on/or about        days into the menstrual cycle

    • 5

    • 10

    • 15

    • 20

    Correct Answer
    A. 15
    Explanation
    During the menstrual cycle, the ovaries develop fluid-filled sacs called follicles, which contain eggs. Around day 14 of the menstrual cycle, one dominant follicle will rupture and release the egg. This process is known as ovulation. Therefore, the correct answer is 15, as it represents the approximate day when the follicles in the ovary rupture to release the egg.

    Rate this question:

  • 24. 

    If the oviduct is ligated, the egg cannot be fertilized or reach the uterus/womb 

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    If the oviduct is ligated, it means that it is surgically closed or tied off, preventing the egg from being fertilized or reaching the uterus/womb. This is because the oviduct is the tube through which the egg travels from the ovary to the uterus, and if it is blocked or closed off, the egg cannot pass through and therefore cannot be fertilized or reach the uterus. Therefore, the statement "if the oviduct is ligated, the egg cannot be fertilized or reach the uterus/womb" is true.

    Some anabolic steroids taken by athletes cause a lower production of testosterone

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    Anabolic steroids, when taken by athletes, can lead to a decrease in the production of testosterone. This is because the use of these steroids can disrupt the natural hormone balance in the body, leading to a suppression of testosterone production. As a result, athletes who misuse anabolic steroids may experience a decrease in their natural testosterone levels. This can have various negative effects on their health and performance.

  • 27. 

    Energy used by the sperm to swim up the female system comes primarily from glycosis

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. True
    Explanation
    The statement is true because glycolysis is the process by which glucose is broken down to produce energy in the form of ATP. Sperm cells rely on this process to obtain the necessary energy for their motility and to swim up the female reproductive system. Glycolysis occurs in the cytoplasm of the sperm cell and provides the energy needed for the sperm to propel itself towards the egg for fertilization. Therefore, it can be concluded that the energy used by the sperm to swim up the female system primarily comes from glycolysis.

    The labia major and minor of females are derived from the same tissue as the scrotal sac of males

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The labia major and minor in females and the scrotal sac in males are derived from the same embryonic tissue called the genital tubercle. During fetal development, this tissue can differentiate into either male or female genitalia depending on the presence or absence of certain hormones. Therefore, it is true that the labia major and minor in females are derived from the same tissue as the scrotal sac in males.

    Most of the fluid in semen is produced by the        

    • Testes

    • Seminal vesicles

    • Bulbourethral glands

    • Prostate gland

    Correct Answer
    A. Seminal vesicles
    Explanation
    The seminal vesicles are responsible for producing most of the fluid in semen. This fluid contains various substances, including fructose, prostaglandins, and enzymes, which provide nourishment and support for sperm. The fluid from the seminal vesicles also helps to neutralize the acidity of the vagina, creating a more favorable environment for sperm survival and movement. Therefore, the seminal vesicles play a crucial role in the composition and function of semen.

    Contraceptive methods that rely on synthetic hormones

    • Prevent implantation of fertilized eggs

    • Prevent ovulation

    • Prevent the sperm and egg from meeting

    • Kill sperm

    Correct Answer
    A. Prevent ovulation
    Explanation
    The correct answer is "prevent ovulation." Contraceptive methods that rely on synthetic hormones work by inhibiting the release of eggs from the ovaries, thus preventing ovulation. This means that there is no egg available for fertilization by sperm, effectively preventing pregnancy.

    Rate this question:

    The most important function of sexual reproduction is 

    • Preserving genetic purity

    • Keeping genes from changing

    • Creating genetic variability

    • Limiting genetic recombination

    • Producing identical offspring

    Correct Answer
    A. Creating genetic variability
    Explanation
    Sexual reproduction is the process by which offspring are produced through the combination of genetic material from two parents. One of the key advantages of sexual reproduction is the creation of genetic variability. This is achieved through the random assortment of genes during the formation of gametes and the subsequent recombination of these genes during fertilization. Genetic variability is important for the survival and adaptation of a species to changing environments, as it allows for the generation of new combinations of genes, increasing the chances of advantageous traits being passed on to future generations.

    Sperm are stored mostly in       

    • Cowpers gland

    • Prostate

    • Seminal vesicle

    • Vas deferens and epidydimus of the testes

    Correct Answer
    A. Vas deferens and epidydimus of the testes
    Explanation
    The sperm are stored mostly in the vas deferens and epididymis of the testes. The vas deferens is a tube that carries sperm from the epididymis to the urethra during ejaculation. The epididymis is a coiled tube located on top of the testes where sperm mature and are stored. These structures play a crucial role in the transportation and storage of sperm before they are released during sexual intercourse.

    Rate this question:

  • 35. 

    Which of the following will give males trouble as they age?

    • Corpora cavernosa

    • Corpora spongiosum

    • Prostate gland

    • Cowpers gland

    Correct Answer
    A. Prostate gland
    Explanation
    As males age, the prostate gland can cause trouble. The prostate gland is a small gland located below the bladder and in front of the rectum. It is responsible for producing fluid that nourishes and protects sperm. However, as men age, the prostate gland can enlarge and lead to a condition called benign prostatic hyperplasia (BPH). This can cause urinary problems such as frequent urination, difficulty starting and stopping urination, weak urine flow, and the feeling of incomplete bladder emptying. In some cases, BPH can also lead to more serious complications like urinary tract infections and bladder stones.

    LH = ovulation

    • True

    • False

    Correct Answer
    A. True
    Explanation
    LH (luteinizing hormone) is indeed associated with ovulation. LH surge occurs in the middle of the menstrual cycle and triggers the release of a mature egg from the ovary, which is known as ovulation. This surge in LH levels can be detected through ovulation predictor kits. Therefore, the statement "LH = ovulation" is true.

    Sperm are no longer ejected after a vasectomy because the         is cut or ligated?

    • Epididymis

    • Vas deferens

    • Urethra

    • Weiner

    Correct Answer
    A. Vas deferens
    Explanation
    After a vasectomy, sperm are no longer ejected because the vas deferens is cut or ligated. The vas deferens is a tube that carries sperm from the testicles to the urethra for ejaculation. By cutting or ligating the vas deferens during a vasectomy, the pathway for sperm to be released is blocked, preventing them from reaching the urethra and being ejaculated. This is a permanent form of contraception as it prevents sperm from being present in the ejaculate.

    Seminal fluid, excluding the sperm, is produced by all except

    • Cowpers gland

    • Prostate

    • Seminal vesicle

    • Ovary

    Correct Answer
    A. Ovary
    Explanation
    Seminal fluid, which is responsible for nourishing and protecting the sperm, is produced by the Cowpers gland, prostate, and seminal vesicle. The ovary, on the other hand, is not involved in the production of seminal fluid. Instead, the ovary is responsible for producing eggs (ova) in females. Therefore, the correct answer is ovary.

    Initiation of both egg and sperm production is controlled by         , whereas testosterone production by the interstitial cells of Leydig is controlled by         

    • Progesterone, Estrogen

    • LH, FSH

    • FSH, LH

    • Unicorn semen, rainbows

    Correct Answer
    A. FSH, LH
    Explanation
    The initiation of both egg and sperm production is controlled by FSH (follicle-stimulating hormone) and LH (luteinizing hormone). FSH stimulates the development of ovarian follicles in females and the production of sperm cells in males. LH triggers ovulation in females and stimulates the production of testosterone in males by the interstitial cells of Leydig. Therefore, FSH and LH are the hormones responsible for regulating the reproductive processes in both males and females.

    The two hormones of birth control pills would be                  

    • Testosterone and estrogen

    • Testosterone and progesterone

    • Progesterone and FSH

    • Estrogen and progesterone

    • FSH and LH

    Correct Answer
    A. Estrogen and progesterone
    Explanation
    The correct answer is estrogen and progesterone. Birth control pills contain synthetic forms of these two hormones, which work together to prevent pregnancy. Estrogen helps to suppress the release of eggs from the ovaries, while progesterone thickens the cervical mucus, making it difficult for sperm to reach the egg. Additionally, progesterone also thins the lining of the uterus, making it less receptive to implantation. By combining these two hormones, birth control pills are highly effective in preventing pregnancy.

    The endometrium or lining of the uterus prepares for pregnancy each month by becoming more cellular and vascular under the influence of which two hormones?

    • LH

    • Estrogen

    • Progesterone

    • B and C

    • A and C

    Correct Answer
    A. B and C
    Explanation
    The endometrium or lining of the uterus prepares for pregnancy each month by becoming more cellular and vascular. This process is influenced by two hormones: estrogen and progesterone. Estrogen helps to stimulate the growth and thickening of the endometrium, while progesterone further prepares the endometrium for implantation of a fertilized egg by increasing its blood supply and promoting the development of glandular tissue. Therefore, the correct answer is B and C.

    • True

    • False

    • Option 3

    • Option 4

    Correct Answer
    A. False
    Explanation
    The statement "the egg must be fertilized before ovulation" is false. Ovulation is the release of an egg from the ovary, and fertilization occurs when the egg is fertilized by a sperm. In the human reproductive system, fertilization typically occurs in the fallopian tubes after ovulation. Therefore, fertilization does not need to occur before ovulation.
