Q2.What happened when we inoculate Rhizobium in the wheat field?
Solution
a) When we inoculate Rhizobium in wheat field there is no increase in production and the nitrogen content of soils remains same because Rhizobium is a symbiotic bacterium that lives in root nodules of legumes and fixes atmospheric nitrogen into organic compounds

Q5.Which of the following can be controlled by using biopesticides?
Solution
d) Biopesticides are pesticides of biological origin, which may be of various types depending upon the types of pests killed or controlled by them, e.g., algicides, fungicides bacteriocides, herbicides or weedicides, insecticides, nematicides and rodenticides, etc. These were initially employed to protect crop plants against pests but they are non equally important for destroying or controlling vectors for various animals and human pathogens, thus, can be used for controlling various diseases also.

Q6. Consider the following statements
I. Yeast used in making bread and beverages is a prokaryotic fungus II. Streptokinase is produced by
Streptococcus and modified by genetic engineering is used as a clot buster III. Lipases are added in detergent for removing only stains from laundry
IV. Pectinases are used in clearing fruit juices Which of the statement given above are correct?

IV. Pectinases are used in clearing fruit juices Which of the statement given above are correct?
Solution
c)Yeast used in baking and the alcohol in alcoholic beverages is a type of eukaryotic fungus. Streptokinase is an enzyme obtained from the cultures of some haemolytic bacterium Streptococcus and modified genetically to function as clot busters. Lipases are lipid dissolving enzymes that are obtained from Candida lipolytica and Geotrichum candidum. They are added in detergents for removing oily stains from laundry. Pectinases are obtained commercially from Byssochlamys fulva. Along with proteases, they are used in clearing of fruit juices

Q10.
During the primary treatment of sewage, solid particles that settle down are called
Solution
c) Primary or physical treatment of sewage is the physical removal of large and small particle from sewage. First, the floating debris is removed by sequential filtration by passing through wire mesh screens. Then, the grit (soil and small pebbles) are removed by sedimentation in settling tank. The sediment is called primary sludge and the supernatant is the effluent
