The Reproductive System Welcome to your The Reproductive System 1. What will happen if the temperature of the scrotal sacs temporarily goes to about 2°C lower than normal temperature? Sperm formation will be stopped Scrotal sacs will relax and do down away from the body Scrotal sacs will contract and come close to the body Testes will start rotation movement2. The onset of menstruation in the female is termed as Parthenogenesis Menopause Ovulation Menarche3. Ovulation in mammals is a process in which The egg is released from Graafian follicle The egg is fertilized in fallopian tube The unfertilized egg passes out of female's body The egg passes through fimbriated funnel of fallopian tube4. Semen is the mixture of sperms and secretions from Prostate gland All of these Seminal vesicles Cowper's glands5. In human males, the testes lie in the scrotum because it helps in the Easy transfer of gametes Process of mating Secretion of oestrogen Formation of sperms6. The embryo in humans gets nutrition from the mother with the help of a special tissue called Uterus Villi Placenta Womb7. Corpus luteum in mammals is present in Skin and acts as a pain receptor Ovaries and produces progesterone hormone Heart and initiates atrial contraction Brain and connects the two cerebral hemispheres8. The fixing of the blastocyst to the wall of the uterus or endometrium is called Gestation Fertilization Implantation Parturition9. When pregnancy does not occur the life of the corpus luteum is about 10 days 4 days 14 days 28 days10. Leydig cells produce Progesterone Testosterone Oestrogen Semen11. The stoppage of menstruation in the female is termed as Menarche Ovulation Parthenogenesis Menopause12. Sterilization in the female involves cutting and tying the Ureter Uterus Urethra Oviduct13. Which one of the following is the route that a sperm follows when it leaves the testes of a mammal? Vas deferens→epididymis→urethra Epididymis→Vas deferens→urethra Epididymis→urethra→Vas deferens Urethra→epididymis→Vas deferens14. In human beings, the fertilization occurs in the Fallopian tubes Vagina Ovaries Uterus15. Fertilization means The shedding of gametes from a reproductive organ The fusion of nuclei of male and female gametes The transfer of male gamete to the female gamete The meeting of male and female gametes16. 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 days17. If the vas deferens of a man are surgically disconnected or removed Sperms in the semen will be without nuclei Sperms in semen will be non-motile Spermatogenesis will not take place Semen will be without sperms18. The normal gestation period in humans is 285 days 280 days 270 days 290 days19. The site of maturation of human sperms is the Epididymis Interstitial cells Prostate gland Seminiferous tubule20.
