Q : Which of the following role/roles is/are played by epididymis, vas deferens, vas deferens and prostate gland in the male reproductive system of human?
(A) spermatogenesis and motility of sperms
(B) maturation and motility of sperms
(C) spermatogenesis and maturation of sperms
(D) sperm motility only
Detailed Solution. Maturation of sperms occurs in Epididymis, while the vas deferens help in the motility of sperms. Two glands storing and producing the fluid that makes up the semen are called the seminal vesicles. The fluid from the seminal vesicles gets expelled to the ejaculatory duct during ejaculation.
Which one of the following is not a component of the human male reproductive system?
(A) Seminal Vesicle
(B) Uterus (Cervix)
(C) Urethra
(D) Vas Deferens
The correct answer is Cervix. Cervix is not a component of the human male reproductive system. Cervix facilitates the passage of sperm into the uterine cavity.
When the gamete cells of two individuals combine during sexual reproduction, they form
(A) Fetus
(B) Endosperm
(C) Zygote
(D) Egg
During sexual reproduction, two haploid gametes combine into one diploid cell known as a zygote in a process called fertilization. The nuclei from the gametes fuse, and each gamete contributes half of the genetic material of the zygote.
Which one of the following is a specific type of milk that is produced in a lactating mother and is essential for the development of an immune response in a human newborn?
(A) Transitional Milk
(B) Skimmed Milk
(C) Neonatal (Colostrum)
(D) Milk produced in breast one month after the birth of the baby
Colostrum is the first form of breastmilk that is released by the mammary glands after giving birth. It's nutrient-dense and high in antibodies and antioxidants to build a newborn baby's immune system. It changes to breast milk within two to four days after your baby is born.
In which part of the male reproductive system is the main genetic material found?
(A) in the prostate gland
(B) in the ureter
(C) in sperm
(D) in the testicles
The sperm. The sperm is the male reproductive cell. Its role is to fertilise an egg. It contains the man's genetic material.
The vas deferens joins with the tube coming from the bladder to form a common passage called
(A) Ureter
(B) Testes
(C) Urethra
(D) Vas Deferens
The sperms are formed in the testes and are transported through the vas deferens into the urethra. This urethral tube unites with a tube coming from the urinary bladder. The urethra thus forms a common passage for both the sperms and urine.
Which process of fusion of sperm and ovum results in the formation of a structure called zygote?
(A) Fertilization
(B) Tissue Culture
(C) Function
(D) Fragmentation
Fertilization is a process of fusion of gametes to form zygotes. A zygote is a single cell which is formed by the fusion of male and female gametes during sexual reproduction.
The age during which the reproductive organs of males and females become functional, the gonads start producing gametes and sex hormones, and mature for human sexual activity.
(A) Parthenogenesis
(B) Sexual Reproduction
(C) Coupler
(D) Puberty
Puberty is the process of physical maturation where an adolescent reaches sexual maturity and becomes capable of reproduction. On average, puberty typically begins between 8 and 13 in females and 9 and 14 in males.
In the body of the male reproductive system, the testes are located in a sac outside the abdominal cavity, which is called.
(A) Scrotum
(B) Glands
(C) Seminiferous Tubules
(D) Scrotum
The testes in humans are situated outside the abdominal cavity inside a pouch called scrotum.
Patients suffering from gouty arthritis due to increased serum uric acid level should minimize intake of which one of the following food components?
(A) dietary fiber
(B) nucleic acid
(C) lipid
(D) carbohydrates
The correct answer is Nucleic Acids. Gout is a type of arthritis that causes inflammation in one joint. It is caused due to the elevated serum uric acid level in the joint. Meat which is generally consumed by humans, including seafood and organ meats, has high levels of nucleic acids.
