1 Kingdom Animalia 1. (a) Amphiuma (b) Ichthyophis (a) Presence of notochord (c) Necturus (d) Salamander (b) Presence of vertebral column 2. [BHU 1988] One character is given wrongly for phylum chordata mark it 9.

(a) Metamerism Diapsid skull is found in the following [MP PMT 2001] (a) Crocodile, Turtle and Seymouria (b) Axiate organization (b) Sphenodon, Crocodile and Viper (c) Bilateral symmetry (c) Natrix, Draco and Turtle (d) Pharyngeal gill slits 3. Exclusively aquatic reptiles are included under the group (c) Paired gill slits connected with the exterior (d) Calotes, Cobra and Varanosaurus Which one of the following invertebrates deuterostome and enterocoelous coelomate is a 11. Which of the following is not found in birds [MP PMT 2000] [CBSE PMT 1999] 4. (a) Pila (b) Ascaris (c) Aphrodite (d) Asterias Which one of the following sets of animals belongs to the same class of a phylum [CPMT 1983] 12. Ornithorynchus is a [MP PMT 2002] (d) Mammal (d) Whale, otter, kangaroo Scoliodon is called dogfish due to one of its following characteristics [MP PMT 2000] 13. Schizocoelic type of coelom is present in the (a) Protochordata (a) Mouth (b) Gait (b) Echinoderms (c) Carnivorous (d) Power of smell (c) Nematodes Jaws are absent in (d) Annelids (a) Protochordata 14. Which of the following group is Deuterostome[RPMT 2001] (b) Protochordata and cyclostomata (a) Annelida, Arthropoda, Mollusca (c) Amphioxus and balanoglossus (b) Echinodermata, Hemichordata, Chordata (d) Herdmania and myxine 8. (d) Pectoral girdle (c) Connecting link between reptiles and birds (c) Spider, scorpion, centipede 7. (c) Pelvic girdle (b) Flightless bird (b) Bat, pigeon, whale 6. (b) Fore limb (a) Fossil bird (a) Hydra, jelly fish, cray fish 5. (a) Hind limb (c) Annelida, Mollusca. Chordata Scales in chondrichthyes are [AIIMS 2000] (a) Placoid (b) Ganoid (c) Cycloid (d) Sesamoid (d) Arthropoda, Mollusca, Echinodermata Which one of the animal of amphibia has no tongue (SET –7) E1M1 Institute Allahabad Ph.: 7388125888,7388124999 Kingdom Animalia 2 1 b 2 d 3 d 4 d 5 d 6 b 7 a 8 b 9 d 10 b 11 b 12 d 13 d 14 b 15 d 16 b 17 d 18 a 19 a 20 a 21 d 22 c 23 d 24 b 25 d 26 d 27 c 28 b 29 d 30 b 1. (b) Vertebral column is present in the vertebrates only. It is not present in all the chordates. 2. (d) Chordates show the presence of Notochord and pharyngeal gill slits. 3. (d) Echinodermata and all chordates are deuterostome and enterocoelous. 4. (d) Because they are belong to the class mammalia. 5. (d) In scaliodon, olfactory organs are characteristically large in elasmobranchs correlated with a highly developed sense of smell for perception of chemical substances dissolved in water. nerve cord, 6. (b) Cyclostomata is a class of group Agnatha. Where paired appendages girdles and jaw are absent. Some workers include even the protochordates in Agnatha. 7. (a) Placoid scale has a disc like basal plate. It resembles a tooth. These scales are found in cartilagenous fishes (chondricthyes). 8. (b) Icthyophis is a limbless amphibian showing parental care. It has no tongue. 9. (d) In crocodilia, includes crocodiles, gharials and alligators. These are the largest living fresh water reptiles. 11. (b) In birds, forelimbs are modified as wings for flying. Therefore, the forelimb is not found in birds. 12. (d) Ornithorynchus or duck bill platypus is an egg laying mammal. 13. (d) Annelids are the first group of animals to show true coelom in the animal kingdom. Coelom is formed by the splitting of the mesoderm. Hence it is called schizocoelic coelom. 14. (b) Deuterostomes includes Echinodermata, Hemichordata and chordata. The mouth is derived away from the blastopore. 15. (d) Hermaphrodite animals means monoecious. 16. (b) Coelenterates are diploblastic animals i.e. derived only from two embryonic germ layers. Ectoderm and endoderm. They show radial symmetry. 17. (d) Hypnotoxin is secreted by nematocyst cell of tentacles of hydra to paralyse the active prey for easy engulfing. 18. (a) Loss of gravid proglattids from posterior end of body is called apolysis. 19. (a) Female is with straight posterior end of the body. 20. (a) Because they are supposed to be associated with the function of excretion just like liver. 22. (c) In diptera, hindwings are greatly reduced to drumstick shaped structures, called halters. These carry sense organs and serve as balancing organ during flight. 23. (d) Skeleton of sponges is secreted by sclerocytes. 24. (b) A life-style characterized by activity during the night rather than at day. 25. (d) An individual with both male and reproductive organs called hermaphrodite. 26. (d) Blind sac body plane is exhibited by some eumatazoans like coelenterates and Platyhelminthes, in which have single opening acts as both mouth and anus. 27. (c) Digestion of Hydra is completed into two phase. A preliminary extra cellular phase in gastrodermis cavity and the final, intracellular phase in the food vacuoles of nutritive muscular cells of gastrodermis. 28. (b) The second stage of juvenile is infective stage of Ascaris which is also called embryonated egg. 29. (d) Annelids are first animals in which closed circular system, metamerism segmentation and true coelom is evolved. On the basis of these comments annelids are advanced over nematoda. 30. (b) Presence of two pair antennae is character of class crustacea. Antennae are sensory and help in searching food and shelter. *** E1M1 Institute Allahabad Ph.: 7388125888,7388124999 female
