Following sets of Plasmodium falciparum sporozoites (i). Normal sporozoites; (ii) Sporozoites with mutation in the C-terminal of circumsporozoite (CS) antigen; (iii). Sporozoites with mutation in the N-terminal region of circumsporozoite (CS) antigen are injected into 2 groups of mice, one normal (Group A) and one (Group B) where localized knock down of heparin sulfate receptor for CS antigen in liver cells is achieved by injecting specific shRNA expressing lentiviral particles in the liver prior to infection. 15 days post infection, parasitemia is measured by counting infected RBC through Giemsa staining. Which of the following groups will show maximum level of parasitemia? (CSIR_2015_I)

The following statements are related to excretion of invertebrates: (A). Flame cells are found in mollusks and jelly fish. (B). Nephridia and Malphigian tubules convert ammonia to urea for water conservation. (C). Green glands are found in flatworms and help in the excreta elimination. (D). Excretory canals in nematodes carry waste materials to excretory pores in the body wall. Choose the correct answer (CSIR_2015_I)

The list below includes names of animal phyla and classes (A). Echinodermata (B). Cephalopoda (C). Annelida (D). Mollusca (E). Hidurinea (F). Asteroidea (G). Arthropoda (H). Crustacea For a leech and lobster, the correct classification of phylum and class respectively is: (CSIR_2015_I)

Some key characteristics of the four classes of phylum Mollusca are listed below: (A). They have two lateral (left and right) shells (valves) hinged together dorsally; they do not have distinct head or radula; they disperse from place to place largely as larvae (B). They generally creep on their foot; the heads of most of this group have a pair of tentacles with eyes at the end; during embryological development, they undergo torsion. (C). They have oval bodies with overlapping calcareous plates; underneath the plates, the body is not segmented; they creep along using a broad, flat foot surrounded by a groove or mantle cavity in which the gills are arranged. (D). They have high developed nervous system; most members of this class have closed circulatory systems. The correct matched of the above characteristics with the classes of Mollusca is: (CSIR_2015_I)

The diagram below depicts a simplified three of life with three domains and one of the domains including Whittaker’s three major kingdoms. Which of the following is the correct naming of the numbered boxes? (CSIR_2015_I)

Sleeping sickness is disease caused by a protozoan parasite and the following statements pertain to that diseases: (A). The vector for this disease is tsetse fly. (B). The vector for this disease is Trypanosoma brucei. (C).The parasite’s body is covered by a dense coat of variable surface glycoprotein (VSG). (D). There are several thousands of VSG genes, only one of them expressing at a time, which helps the parasite in evading host’s immune response. (E). Several thousand copies of VSG genes expresses concurrently, paralyzing the host immune system. Which of the following is the correct combination of the statements given above? (CSIR_2015_I)
