Hello! Welcome to Test Biology Mock 1 - Human Reproduction Instructions: Time: 15 min Full Marks: 120 All questions carry equal marks and all 30 questions carry 4 marks each. You will be awarded minus one marks for each wrong answer. There is no deduction for an unattempted question. The result will be mailed you on the email id provided.

Which represents Mullerian duct in males Cowper's gland Urethra Seminal vesicle Prostatic utricle 2. In mammals, failure of testes to descend into the scrotum is known as Castration Cryptorchidism Impotency Paedogenesis 3. At the time to sexual excitation, muscles in the penis Relaxed Collapsed Contracted None4. Scrotum communicates with the abdominal cavity through Vas - deferens Urethra Epididymis Inguinal canal 5. Seminiferous tubules are composed of Germinal epithelium Spermatogonia Glandular epithelium Sensory epithelium6. Cryptorchidism is a condition of testes Having been surgically removed Unable to produce sperms Unable to descend in scrotal sac Having remained undeveloped7. Location and secretion of Leydig cells are Pancreas-- Glucagon Testis -- Testosterone Ovary -- Oestrogen Liver -- Cholesterol8. If the epididymis is not present then what will happen: Early cross the pathway Functional maturation is early Sperm cycle is short Sperm gradually disappear in semen 9. What is the oligospermia condition If sperm count is < 60 million / ml If sperm count is 40 - 120 million / ml If sperm count is < 20 million /ml If sperm count is 20 million to 40 million /ml 10. Nutritive cells of Seminiferous tubules are Leydig cells Sertoli cells Atretic follicular cells Spermatogonial cells 11. What will happen if vasa deferentia of a man are cut? Spermatozoa are non - nucleate Sperms are non- motile Semen is without sperms Spermatogenesis does not occur 12. Sertoli cells are regulated by the pituitary hormone known as: FSH LH GH Prolactin13. The vaginal cavity of tunica vaginalis is found in Vagina of female Testis of male Ovaries of female None 14. The vagina of a female reproductive system is Essential sex organ Primary sex organ Secondary sex organ None15. Bartholin's gland occurs in Females and helps in vestibular lubrication Males and form liquid part of spermatic fluid Females and produce oestrogen for regulating secondary sexual characters Males and produce alkaline fluid for neutralising urethral acidity 16. Lower narrow end of uterus is called Clitoris Urethra Vulva Cervix17. What is the arborvitae uteri? Inner most layer of uterus Mucosal fold of cervix White matter of cerebellum wall of vagina 18. During differentiation, the spermatids remain associated with Spermatogonia Sertoli cells kuffer's cells Leydig cells 19. Spermiogenesis is a process in which Spermatogonia produce a spermatid Spermatocytes give rise to spermatozoa Spermatids change into Spermatozoa Dormant spermatozoa become active just before ejaculation 20. Hyaluronic acid which binds corona radiata cells is a Homopolysaccharide Mucopolysaccharides Amino Acids Glycoprotein21. Acrosome formation in spermatogenesis occurs in which stage Spermiogenesis Growth phase second meiotic divisions first meiotic divisions22. Which part of sperm enters in eggs in humans? Only head Head + Acrosome Head and middle piece Complete sperm 23. Correct order of spermatogenesis is Spermatogonia - Spermatids - Spermatocytes - sperm Spermatogonia - primary Spermatocytes - secondary Spermatocytes- Spermatids - sperm Spermatocytes- Spermatogonia - Spermatids - sperm Spermatids - Spermatogonia- Spermatocytes- sperm 24. How many secondary spermatocytes will form 400 spermatozoa: 200 100 40 40025. At the end of the first meiotic division, male germ cell differentiates into Primary spermatocytes secondary spermatocytes Spermatogonium Spermatid 26. The head of mature mammalian sperm is made of? Elongated nucleus covered by acrosome Nucleus, Acrosome, cytoplasm, and mitochondrial sheath An Acrosome Two centrioles and an axial filament 27. An egg of bird was coated with varnish and then incubated. The egg did not hatch because the developing embryo died because of toxic effects of varnish Could not utilise yolk in the pressure of excess amount of nitrogenous wastes. died because of depleted oxygen supply could not excrete and died 28. Which of the following is haploid? Primary spermatocytes and primary oocytes Spermatogonia and oogonia Germinal cells secondary spermatocytes and secondary oocytes29. Isolecithal eggs are found in Birds Humans Insects Frogs30. The primary egg membrane of mammalian's egg is termed Zona pellucida Corona radiata Chorion Vitelline membraneThanks for attempting mock at Kailasha Foundation.
