(Powered By: Kailasha Foundation - Fun & Learn Portal) Note: This mock looks best on a desktop. Email Name 1. Which of the following is the correct match? Microlecithal egg - Reptiles Centrolecithal egg - Insects Megalecithal egg - Eutherian mammals Alecithal egg - Birds2. Homolecithal eggs are found in Amphioxus, tunicates and mammals Amphioxus fish and Amphibia Birds, reptiles and monotrems Petromyzon, tunicates and Chondrichthyes3. The oocyte is liberated from ovary under the influence of LH, after completing: Meiosis Mitosis and before liberating polar bodies Meiosis 1 and before liberating second polar bodies Meiosis 2 and after release of first polar body 4. In a 30-year-old lady, eggs are released in the form of Oogonia Secondary oocyte Atretic follicle Primary oocyte 5. Estrogen is secreted by Pituitary Germinal epithelium of ovary Corpus luteum Membranous granulosa of graffian follicle 6. Graffian follicle are found in Ovary of mammals Ovary of frog Testis of mammal Ovary of cockroach7. Number of eggs released in the lifetime of a woman is approximately 4000 40 400 200008. Which temporary endocrine gland forms in ovary after ovulation Corpus albicans Corpus luteum Corpus callosum Corpus striata 9. Which of the following is the correct matching of the events occurring during the menstrual cycle? Ovulation -- LH and FSH attain peak level and sharp fall in the secretion of progesterone. Proliferative phase -- Rapid regeneration of myometrium and maturation of graffian follicle Menstruation -- Breakdown of myometrium and ovum not fertilised Development of corpus luteum -- Secretory phase and increased secretion of progesterone. 10. For ovulation in reflex ovulation Coitus is not necessary Coitus is necessary Plenty of food is necessary None11. Corpus luteum is Endocrine Excretory Digestive Reproductive12. If the menstrual cycle is if 35 days then what is the risk period (cycle start on 1st day) 18th - 35th day 11th - 18th day 16th- 24th day 9th - 17th day13. Ovulation occurs under the influence of FSH LH Estrogen Progesterone14. Ovulation in the human female normally takes place during the menstrual cycle At the mid Secretory phase Just before the end of secretory phase At the beginning of the proliferative phase At the end of the proliferative phase15. Which is correct Menstrual cycle is present in all primates Estrous cycle occurs in all animals Most mammals are ovoviviparous Menstrual cycle is present in all mammals 16. Immediately after ovulation, the mammalian egg is covered by a membrane called Chorion Zona pellucida Corona radiata 2 & 3 17. The site of fertilization in the mammal is Uterus Vagina Fallopian tube Ovary 18. Adaptation for the approach of sperm of egg in mammals very high number of sperms Sperm kept inactive till ejaculation Peristalsis of oviduct All of the above 19. Antifertilizin is Glycoprotein Carbohydrate Simple acidic protein None20. Polyspermy is normally prevented by Formation of fertilization membrane Repulsion of excess number of sperm by ova The fertilizin and antifertilizin reaction Inability of some sperm to penetrate ova21. Fertilizing are emitted by Sperms Mature eggs Immature eggs Polar bodies 22. The blastomeres in the blastocyst are arranged into an outer layer called -----A------ and inner group of cells attached to trophoblast called the -----B-----. A are inner cell mass and B is trophoblast Both are inner cell mass Both are trophoblast A is trophoblast and B are inner cell mass 23. Cleavage starts in the zygote In vagina In cervix In fallopian tube In uterus 24. Meroblastic cleavage takes place in Chick Frog Hydra Amphioxus25. Movement of blastomeres usually seen in which embryonic stage Blastula Gastrula Morula In all embryonic stages 26. Which of the following is not correct for gastrulation? Archenteron is formed Morphogenetic movements Some blastomeres and blastocoel degenerate All germinal layers are formed27. The cavity formed during gastrulation and found in mature gastrula Archenteron Pseudocoel Neurocoel Blastocoel28. Correct sequence in development is Fertilisation-- Zygote --Blastula -- Morula -- Cleavage-- Gastrula Cleavage-- Zygote -- fertilisation-- morula --Blastula -- Gastrula Fertilization -- cleavage -- Morula -- zygote -- Blastula -- Gastrula Fertilization -- zygote -- cleavage - Morula -- Blastula -- gastrula 29. A placenta is the region where Foetus is covered by membranes Foetus receives nourishment from mother's blood Foetus is provided with mother’s blood Foetus is attached to mother by spermatic cord 30. Parturition duct in female is called Oviduct Uterus Vagina CervixThanks for attempting mock at Kailasha Foundation. There are many other mocks for NEET on various topics.
