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 passes through fimbriated funnel of fallopian tube The egg is fertilized in fallopian tube2. In human males, the testes lie in the scrotum because it helps in the Process of mating Easy transfer of gametes Formation of sperms Secretion of oestrogen3. Corpus luteum in mammals is present in Ovaries and produces progesterone hormone Heart and initiates atrial contraction Skin and acts as a pain receptor Brain and connects the two cerebral hemispheres4. The normal gestation period in humans is 285 days 270 days 280 days 290 days5. In females, after how much time after fertilization does the fertilized egg get implanted in the uterine wall? One month Three weeks Few months About seven days6. Semen is the mixture of sperms and secretions from All of these Prostate gland Cowper's glands Seminal vesicles7. In human beings, the fertilization occurs in the Uterus Fallopian tubes Ovaries Vagina8. When pregnancy does not occur the life of the corpus luteum is about 4 days 10 days 14 days 28 days9. The onset of menstruation in the female is termed as Parthenogenesis Ovulation Menopause Menarche10. If the vas deferens of a man are surgically disconnected or removed Sperms in the semen will be without nuclei Spermatogenesis will not take place Sperms in semen will be non-motile Semen will be without sperms11. Fertilization means The fusion of nuclei of male and female gametes The meeting of male and female gametes The transfer of male gamete to the female gamete The shedding of gametes from a reproductive organ12. The site of maturation of human sperms is the Seminiferous tubule Interstitial cells Epididymis Prostate gland13. The stoppage of menstruation in the female is termed as Menarche Menopause Ovulation Parthenogenesis14. The embryo in humans gets nutrition from the mother with the help of a special tissue called Placenta Uterus Womb Villi15. Leydig cells produce Progesterone Semen Oestrogen Testosterone16. Sterilization in the female involves cutting and tying the Ureter Urethra Uterus Oviduct17. What will happen if the temperature of the scrotal sacs temporarily goes to about 2°C lower than normal temperature? Scrotal sacs will contract and come close to the body Sperm formation will be stopped Scrotal sacs will relax and do down away from the body Testes will start rotation movement18. The fixing of the blastocyst to the wall of the uterus or endometrium is called Parturition Implantation Gestation Fertilization19. The middle piece of the sperm provides Chromosomes Gene Food Energy20. 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 deferens21 out of 20Please fill in the comment box below.
