The Reproductive System Welcome to your The Reproductive System 1. The site of maturation of human sperms is the Interstitial cells Prostate gland Seminiferous tubule Epididymis2. Which one of the following is the route that a sperm follows when it leaves the testes of a mammal? Urethra→epididymis→Vas deferens Vas deferens→epididymis→urethra Epididymis→urethra→Vas deferens Epididymis→Vas deferens→urethra3. In females, after how much time after fertilization does the fertilized egg get implanted in the uterine wall? Three weeks One month About seven days Few months4. If the vas deferens of a man are surgically disconnected or removed Sperms in semen will be non-motile Sperms in the semen will be without nuclei Semen will be without sperms Spermatogenesis will not take place5. Sterilization in the female involves cutting and tying the Uterus Oviduct Urethra Ureter6. Leydig cells produce Testosterone Oestrogen Progesterone Semen7. In human males, the testes lie in the scrotum because it helps in the Easy transfer of gametes Secretion of oestrogen Formation of sperms Process of mating8. 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 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 body9. In human beings, the fertilization occurs in the Uterus Fallopian tubes Ovaries Vagina10. Fertilization means The meeting of male and female gametes The fusion of nuclei of male and female gametes The transfer of male gamete to the female gamete The shedding of gametes from a reproductive organ11. The middle piece of the sperm provides Energy Chromosomes Food Gene12. The stoppage of menstruation in the female is termed as Parthenogenesis Menopause Ovulation Menarche13. The fixing of the blastocyst to the wall of the uterus or endometrium is called Implantation Fertilization Parturition Gestation14. When pregnancy does not occur the life of the corpus luteum is about 14 days 4 days 10 days 28 days15. The embryo in humans gets nutrition from the mother with the help of a special tissue called Uterus Villi Womb Placenta16. Semen is the mixture of sperms and secretions from All of these Prostate gland Cowper's glands Seminal vesicles17. The normal gestation period in humans is 270 days 290 days 285 days 280 days18. Corpus luteum in mammals is present in Skin and acts as a pain receptor Heart and initiates atrial contraction Brain and connects the two cerebral hemispheres Ovaries and produces progesterone hormone19. The onset of menstruation in the female is termed as Menopause Ovulation Menarche Parthenogenesis20. Ovulation in mammals is a process in which The egg is released from Graafian follicle The unfertilized egg passes out of female's body The egg is fertilized in fallopian tube The egg passes through fimbriated funnel of fallopian tube21 out of 20Please fill in the comment box below.
