Accepted Answer

A

Question 2

What is the probable biological and evolutionary function for a species of desert lizards to to utilize female-only reproduction?
A)This species is probably going extinct and parthenogenesis is a last ditch effort at reproduction.
B)Parthenogenesis attracts males to the all female population.
C)Parthenogenesis allows lizards to save energy by limiting diversity.
D)Parthenogenesis results in the crossing-over of chromosomes and does not exhibit any evolutionary benefit.

Accepted Answer

Parthenogenesis allows lizards to reproduce without males, which can be advantageous in environments where finding mates is difficult, such as deserts. It saves energy and resources by not requiring mating, while still allowing the species to persist.

Question 3

Which of the following statements about asexual reproduction is NOT true?
A)Asexual reproduction occurs with only one parent.
B)Asexual reproduction is less commonly used by vertebrates.
C)Asexual reproduction can occur by budding or by division and regeneration.
D)A large number of offspring can be produced in this way in a short time.
E)Asexual reproduction produces variation that allows the species to adapt quickly to changing environmental conditions.

Accepted Answer

Asexual reproduction typically produces genetically identical offspring, leading to less genetic variation and adaptability compared to sexual reproduction.

Question 4

All of the following animals are likely to undergo parthenogenesis EXCEPT
A)humans.
B)flatworms.
C)fish.
D)lizards.
E)insects.

Accepted Answer

Humans do not undergo parthenogenesis, which is the development of an embryo from an unfertilized egg.

Question 5

Trace the correct path of the sperm during ejaculation.
A)urethra,vas deferens,seminal vesicles,testes
B)testes,urethra,vas deferens,penis
C)seminiferous tubules,epididymis,vas deferens,urethra
D)seminiferous tubules,vas deferens,epididymis,urethra
E)vas deferens,seminiferous tubules,epididymis,urethra

Accepted Answer

The correct path of the sperm during ejaculation is from the seminiferous tubules in the testes to the epididymis, then to the vas deferens and finally into the urethra. The seminal vesicles are not involved in the transportation of sperm but rather contribute fluids to the semen.

Question 6

In a species of desert lizard,only females are known to exist.When two females court prior to reproduction,it is necessary for one lizard to assume the posture of a male to stimulate the other female to ovulate.This is a case of
A)hermaphroditism.
B)parthenogenesis.
C)angiogenesis.
D)bisexuality.

Accepted Answer

This is a case of parthenogenesis, where reproduction occurs without fertilization, and the presence of only females indicates that they reproduce without males.

Question 7

Ultimate control of testes development is by the ________ which secretes ________.
A)anterior pituitary; gonadotropin-releasing hormone
B)anterior pituitary; testosterone
C)seminiferous tubules; inhibin
D)hypothalamus; gonadotropin-releasing hormone
E)hypothalamus; testosterone

Accepted Answer

The hypothalamus secretes gonadotropin-releasing hormone (GnRH), which is the ultimate regulator of testes development by stimulating the anterior pituitary to release gonadotropins.

Question 8

What is parthenogenesis?
A)a sexual means of internal fertilization
B)an asexual means of reproduction involving budding
C)an asexual means of reproduction by splitting or fission into several new individuals
D)a modification of sexual reproduction in which an unfertilized egg develops into a complete individual
E)a sexual means of reproduction by which cross-fertilization occurs between hermaphrodites

Accepted Answer

Parthenogenesis is a form of asexual reproduction where an unfertilized egg develops into a complete individual, without the need for fertilization by a male.

Question 9

Why does semen contain alkaline secretions?
A)Alkaline secretions are less viscous and the sperm can swim better.
B)The female vagina is acidic and thus not a favorable environment for sperm.
C)Sperm are only able to use fructose under alkaline conditions.
D)The pH of semen has no significance.

Accepted Answer

The alkaline secretions in semen help to neutralize the acidic environment of the female vagina, creating a more favorable condition for sperm survival and mobility.

Question 10

Identify the labeled structures of the male reproductive system in the picture.

Accepted Answer

The answer of Identify the labeled structures of the male...

Question 11

The STD ________ causes an inflammation of the liver and is preventable by ________.
A)hepatitis A; vaccination
B)hepatitis B; using a male condom
C)HIV; vaccination
D)gonorrhea; vaccination
E)syphilis; male condom

Accepted Answer

Hepatitis A is a sexually transmitted disease that causes liver inflammation and can be prevented through vaccination.

Question 12

In the human male,sperm cells are produced in the ________ and are supported by the ________.
A)interstitial tissue; cervix
B)urethra; uterus
C)seminiferous tubules; Sertoli cells
D)vas deferens; endometrium
E)seminal vesicles; oviduct

Accepted Answer

Sperm cells are produced in the seminiferous tubules of the testes and are supported by Sertoli cells, which provide nourishment and structural support.

Question 13

All of the following structures are part of the male reproductive system EXCEPT
A)testes.
B)epididymis.
C)penis.
D)fimbriae.
E)prostate.

Accepted Answer

Fimbriae are part of the female reproductive system, associated with the fallopian tubes, not the male reproductive system.

Question 14

A functional advantage of having human testes in the scrotum rather than in the abdomen is
A)lack of room in the abdomen.
B)a shorter sperm duct.
C)more direct blood supply.
D)lower temperature.
E)greater protection to the testes.

Accepted Answer

The scrotum provides a cooler environment than the abdomen, which is essential for optimal sperm production and survival.

Question 15

Which of the following statements describes events during oogenesis?
A)The primary oocyte divides producing two haploid cells.
B)The primary oocyte divides producing four haploid cells.
C)The primary spermatocyte divides producing two spermatids.
D)The primary oocyte divides producing four diploid cells.
E)None of these events occur during oogenesis.

Accepted Answer

During oogenesis, the primary oocyte undergoes meiosis I to produce two haploid cells: a secondary oocyte and a polar body.

Question 16

Which of the following statements about reproduction is NOT true?
A)Gametes are produced by meiosis and may be specialized as eggs or sperm.
B)Hydras may reproduce asexually by budding new individuals from the parent.
C)Asexual reproduction is most advantageous when the environment is continually changing.
D)A hermaphrodite produces both male and female gametes in different specialized gonads.
E)A starfish can be cut into several pieces,and each piece will regenerate all the other parts of the individual.

Accepted Answer

Asexual reproduction is most advantageous in stable environments where adaptation to changing conditions is not necessary, as it produces genetically identical offspring.

Question 17

What structure is produced during meiosis I in the male?
A)secondary spermatocyte
B)immature sperm
C)spermatogonium
D)primary oocyte
E)late spermatid

Accepted Answer

During meiosis I in males, primary spermatocytes divide to form secondary spermatocytes.

Question 18

Which of the following associations of reproductive strategies and their descriptions are correct?
A)oviparous - egg is deposited in external environment
B)ovoviviparous - produce eggs but retain them inside the female body until hatching occurs
C)viviparous - the embryo develops inside the body of the female from which it gains nourishment
D)All of the choices are correct.

Accepted Answer

All the choices correctly describe the reproductive strategies: oviparous species lay eggs outside the body, ovoviviparous species retain eggs inside until they hatch, and viviparous species have embryos that develop inside the female with nourishment from the mother.

Question 19

In the human male,the tube used to carry both sperm and urine is the
A)ureter.
B)seminiferous tubule.
C)vas deferens.
D)urethra.
E)fallopian tube.
