The Reproductive System Welcome to your The Reproductive System 1. The middle piece of the sperm provides Food Chromosomes Gene Energy2. In human males, the testes lie in the scrotum because it helps in the Secretion of oestrogen Easy transfer of gametes Process of mating Formation of sperms3. The fixing of the blastocyst to the wall of the uterus or endometrium is called Parturition Implantation Gestation Fertilization4. In females, after how much time after fertilization does the fertilized egg get implanted in the uterine wall? One month About seven days Three weeks Few months5. In human beings, the fertilization occurs in the Ovaries Fallopian tubes Uterus Vagina6. What will happen if the temperature of the scrotal sacs temporarily goes to about 2°C lower than normal temperature? Scrotal sacs will relax and do down away from the body Sperm formation will be stopped Testes will start rotation movement Scrotal sacs will contract and come close to the body7. The onset of menstruation in the female is termed as Menopause Ovulation Menarche Parthenogenesis8. Leydig cells produce Semen Oestrogen Testosterone Progesterone9. Sterilization in the female involves cutting and tying the Oviduct Uterus Ureter Urethra10. Which one of the following is the route that a sperm follows when it leaves the testes of a mammal? Epididymis→Vas deferens→urethra Urethra→epididymis→Vas deferens Vas deferens→epididymis→urethra Epididymis→urethra→Vas deferens11. Ovulation in mammals is a process in which The unfertilized egg passes out of female's body The egg passes through fimbriated funnel of fallopian tube The egg is released from Graafian follicle The egg is fertilized in fallopian tube12. The embryo in humans gets nutrition from the mother with the help of a special tissue called Womb Uterus Villi Placenta13. The normal gestation period in humans is 280 days 285 days 270 days 290 days14. The stoppage of menstruation in the female is termed as Ovulation Menopause Menarche Parthenogenesis15. If the vas deferens of a man are surgically disconnected or removed Spermatogenesis will not take place Sperms in semen will be non-motile Sperms in the semen will be without nuclei Semen will be without sperms16. Semen is the mixture of sperms and secretions from Prostate gland All of these Cowper's glands Seminal vesicles17. Corpus luteum in mammals is present in Brain and connects the two cerebral hemispheres Ovaries and produces progesterone hormone Heart and initiates atrial contraction Skin and acts as a pain receptor18. The site of maturation of human sperms is the Interstitial cells Epididymis Prostate gland Seminiferous tubule19. When pregnancy does not occur the life of the corpus luteum is about 28 days 14 days 10 days 4 days20. Fertilization means 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 organ The meeting of male and female gametes21 out of 20Please fill in the comment box below.
