2 Technology of biogas production from cow dung was developed inIndia largely due to the efforts Authority of and Natural Gas Agricultural Research Institute and Khadi & VillageIndustries Oil II: STRUCTURAL ORGANISATION IN PLANTS AND ANIMALSUNIT II: STRUCTURAL ORGANISATION IN PLANTS AND ANIMAL71 MICROBES IN HUMAN free-living fungus Trichoderma can be used control of plant butterfly would happen if oxygen availability to activated sludge flocs isreduced? will slow down the rate of degradation of organic center of flocs will become anoxic, which would cause deathof bacteria and eventually breakage of would increase in size as anaerobic bacteria would growaround would grow in large does not help the host plant its phosphorus uptake its tolerance to its resistance to root its resistance to one of the following is not a nitrogen-fixing organism?

3 Holes in Swiss cheese are made by bacterium that produces methane bacterium producing a large amount of carbon fungus that releases a lot of gases during its metabolic residue left after methane production from cattle dung in land as in civil do not , EXEMPLAR sludge should have the ability to settle quickly so that it rapidly pumped back from sedimentation tank to aeration pathogenic bacteria present in waste water while sinkingto the bottom of the settling discarded and anaerobically colloidal organic the items in Column A and Column B and choose correct IColumn correct answer , B-iv, C-iii, , B-iv, C-ii, , B-i, C-ii, , B-ii, C-i, D-ivVERY SHORT ANSWER TYPE does Swiss cheese have big holes? are fermentors? a microbe used for statin production. How do statins lower bloodcholesterol level?

4 Do we prefer to call secondary waste water treatment as biologicaltreatment? for Nucleopolyhydro viruses are being used now a days?20/04/2018 UNIT II: STRUCTURAL ORGANISATION IN PLANTS AND ANIMALSUNIT II: STRUCTURAL ORGANISATION IN PLANTS AND ANIMAL73 MICROBES IN HUMAN has the discovery of antibiotics helped mankind in the field ofmedicine? is distillation required for producing certain alcoholic drinks? the most important characteristic that Aspergillus niger,Clostridium butylicum, and Lactobacillus would happen if our intestine harbours microbial flora exactlysimilar to that found in the rumen of cattle? any two microbes that are useful in is the source organism for ECORI, restriction endonuclease? any genetically modified are blue green algae not popular as biofertilisers? species of Penicillium produces Roquefort cheese?

5 The states involved in ganga action any two industrially important an immune immunosupressive agent? an example of a rod shaped is the group of bacteria found in both the rumen of cattle andshidge of sewage treatment? a microbe used for the production of Swiss ANSWER TYPE are flocs important in biological treatment of waste water? has the bacterium Bacillus thuringiensis helped us in controllingcaterpillars of insect pests? do mycorrhizal fungi help the plants harbouring them? are cyanobacteria considered useful in paddy fields? was penicillin discovered? the scientists who were credited for showing the role of Penicillinas an antibiotic? do bioactive molecules of fungal origin help in restoring good healthof humans?20/04/201874 BIOLOGY, EXEMPLAR roles do enzymes play in detergents that we use for washing clothes?

6 Are these enzymes produced from some unique microorganisms? is the chemical nature of biogas. Name an organism which isinvolved in biogas production? do microbes reduce the environmental degradation caused bychemicals? is a broad spectrum antibiotic? Name one such are viruses parasitising bacteria called? Draw a well labelleddiagram of the bacterium has been used as a clot buster? What is its mode are biofertilisers? Give two ANSWER is aerobic degradation more important than anaerobic degradationfor the treatment of large volumes of waste waters rich in organic (a)Discuss about the major programs that the Ministry of Environmentand Forests, Government of India, has initiated for saving major Indianrivers from pollution.(b) ganga has recently been declared the national river . Discuss theimplication with respect to pollution of this a diagrammatic sketch of biogas plant, and label its variouscomponents given below: Gas Holder, Sludge Chamber, Digester,Dung+water the main ideas behind the biological control of pests (a)What would happen if a large volume of untreated sewage is dischargedinto a river ?

7 (b)In what way anaerobic sludge diagestion is important in sewagetreatments? type of food would have lactic acid bacteria. Discuss their
