The Reproductive System Welcome to your The Reproductive System 1. The normal gestation period in humans is 290 days 270 days 280 days 285 days2. In human beings, the fertilization occurs in the Fallopian tubes Vagina Ovaries Uterus3. The embryo in humans gets nutrition from the mother with the help of a special tissue called Villi Uterus Placenta Womb4. Corpus luteum in mammals is present in Skin and acts as a pain receptor Brain and connects the two cerebral hemispheres Heart and initiates atrial contraction Ovaries and produces progesterone hormone5. In human males, the testes lie in the scrotum because it helps in the Secretion of oestrogen Formation of sperms Easy transfer of gametes Process of mating6. Leydig cells produce Semen Progesterone Testosterone Oestrogen7. In females, after how much time after fertilization does the fertilized egg get implanted in the uterine wall? Few months One month Three weeks About seven days8. Semen is the mixture of sperms and secretions from Prostate gland Seminal vesicles Cowper's glands All of these9. Which one of the following is the route that a sperm follows when it leaves the testes of a mammal? Vas deferens→epididymis→urethra Urethra→epididymis→Vas deferens Epididymis→Vas deferens→urethra Epididymis→urethra→Vas deferens10. The stoppage of menstruation in the female is termed as Ovulation Menarche Menopause Parthenogenesis11. If the vas deferens of a man are surgically disconnected or removed Sperms in semen will be non-motile Spermatogenesis will not take place Semen will be without sperms Sperms in the semen will be without nuclei12. The fixing of the blastocyst to the wall of the uterus or endometrium is called Fertilization Gestation Parturition Implantation13. Ovulation in mammals is a process in which The egg is fertilized in fallopian tube The unfertilized egg passes out of female's body The egg is released from Graafian follicle The egg passes through fimbriated funnel of fallopian tube14. The middle piece of the sperm provides Energy Gene Food Chromosomes15. Fertilization means The shedding of gametes from a reproductive organ The fusion of nuclei of male and female gametes The meeting of male and female gametes The transfer of male gamete to the female gamete16. What will happen if the temperature of the scrotal sacs temporarily goes to about 2°C lower than normal temperature? Testes will start rotation movement Scrotal sacs will contract and come close to the body Sperm formation will be stopped Scrotal sacs will relax and do down away from the body17. Sterilization in the female involves cutting and tying the Oviduct Urethra Uterus Ureter18. The site of maturation of human sperms is the Seminiferous tubule Prostate gland Epididymis Interstitial cells19. When pregnancy does not occur the life of the corpus luteum is about 14 days 4 days 28 days 10 days20. The onset of menstruation in the female is termed as Menarche Menopause Ovulation Parthenogenesis21 out of 20Please fill in the comment box below.
