Fertilization means The shedding of gametes from a reproductive organ The meeting of male and female gametes The transfer of male gamete to the female gamete The fusion of nuclei of male and female gametes3. In females, after how much time after fertilization does the fertilized egg get implanted in the uterine wall? One month Few months About seven days Three weeks4. Leydig cells produce Semen Progesterone Oestrogen Testosterone5. The stoppage of menstruation in the female is termed as Ovulation Menarche Parthenogenesis Menopause6. 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 mating7. Sterilization in the female involves cutting and tying the Ureter Uterus Urethra Oviduct8. The site of maturation of human sperms is the Interstitial cells Seminiferous tubule Epididymis Prostate gland9. The normal gestation period in humans is 270 days 280 days 290 days 285 days10. In human beings, the fertilization occurs in the Uterus Ovaries Fallopian tubes Vagina11. Semen is the mixture of sperms and secretions from Prostate gland Cowper's glands Seminal vesicles All of these12.

When pregnancy does not occur the life of the corpus luteum is about 14 days 4 days 28 days 10 days14. The middle piece of the sperm provides Food Gene Chromosomes Energy15. If the vas deferens of a man are surgically disconnected or removed Sperms in the semen will be without nuclei Semen will be without sperms Spermatogenesis will not take place Sperms in semen will be non-motile16. 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 tube17. The embryo in humans gets nutrition from the mother with the help of a special tissue called Villi Placenta Uterus Womb18. 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 Urethra→epididymis→Vas deferens Epididymis→urethra→Vas deferens19. Corpus luteum in mammals is present in Skin and acts as a pain receptor Heart and initiates atrial contraction Ovaries and produces progesterone hormone Brain and connects the two cerebral hemispheres20.
