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-motile3. The embryo in humans gets nutrition from the mother with the help of a special tissue called Uterus Villi Placenta Womb4. Semen is the mixture of sperms and secretions from All of these Cowper's glands Prostate gland Seminal vesicles5. The stoppage of menstruation in the female is termed as Ovulation Menarche Parthenogenesis Menopause6. Which one of the following is the route that a sperm follows when it leaves the testes of a mammal? Epididymis→urethra→Vas deferens Epididymis→Vas deferens→urethra Urethra→epididymis→Vas deferens Vas deferens→epididymis→urethra7. 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 tube8. The middle piece of the sperm provides Energy Food Gene Chromosomes9. Corpus luteum in mammals is present in Heart and initiates atrial contraction Skin and acts as a pain receptor Ovaries and produces progesterone hormone Brain and connects the two cerebral hemispheres10. In human males, the testes lie in the scrotum because it helps in the Secretion of oestrogen Process of mating Easy transfer of gametes Formation of sperms11. The normal gestation period in humans is 290 days 270 days 285 days 280 days12. The fixing of the blastocyst to the wall of the uterus or endometrium is called Parturition Implantation Fertilization Gestation13.

Fertilization means The meeting of male and female gametes The fusion of nuclei of male and female gametes The shedding of gametes from a reproductive organ The transfer of male gamete to the female gamete16. The site of maturation of human sperms is the Seminiferous tubule Epididymis Interstitial cells Prostate gland17. The onset of menstruation in the female is termed as Ovulation Menopause Parthenogenesis Menarche18. Sterilization in the female involves cutting and tying the Oviduct Urethra Uterus Ureter19. When pregnancy does not occur the life of the corpus luteum is about 4 days 28 days 14 days 10 days20. What will happen if the temperature of the scrotal sacs temporarily goes to about 2°C lower than normal temperature?
