Physical-Ans Nuclear Chemical Biochemical 2. When nuclear change takes place, which is true Energy is destroyed Energy is released Energy is changed None of these The answer is Energy is released 3. Which type of radiation is unaffected by magnetism ? Alpha Beta GammaAns All of these 4. Which temperature scale is an absolute scale, where the zero point is the lowest possible temperature ? KelvinAns Celsius Fahrenheit Centigrade 5. The relative randomness of molecules in the states of matter is best indicated by Solid > Liquids > Gas Liquid > Gas > Solid Liquid > Solid > Gas Gas > Liquid > SolidAns 6. Whether or not two liquids are miscible is determined by Molecular Size : Molecules of similar sizes tend to mix together Density : Liquids of simliar densities usually mix well together Polarity : Polar and nonpolar liquids are not miscible while polar liquids can usually be mixed with each other Ans All of the above factors directly affect miscibility 7. The Triple Point is The combination of standard temperature, pressure and volume The combination of temperature and pressure at which the solid, liquid and gas phases can coexist at equilibrium The combination of pressure and temperature at which liquid, gas, and plasma phases all exist in equilibrium The combination of temperature and pressure at which liquids and gases cannot be distinguished from each other 8. If the work done by a force depends only on the initial and final stages and not on the path taken, then this type of force will be Conservative Force Non-conservative Force Conservative as well as Non-conservative force None of these 9. Working between which pair of following temperatures, the efficiency of a carnot engine will be maximum ? 10 Degrees F and 10 Degress R 10 Degrees F and 10 Degress C 10 Degrees R and 10 Degress C It will be same in all the above cases 10. Dacron is a Polyester Polyamide Nylon Resin 11. Which of the following has the highest stable atom ? Bi Al Cl Pb 12. In Friedel-Crafts reaction, AlCl3 acts as a Lewis Acid Lewis Base Catalyst Reactant 13. The number of unpaired electrons in [Ni(CO)4] is Zero One Three Five 14. Iodoethane reacts with sodium to form Pentane Propane Butene Butane 15. An ideal gas has maximum density at 1 atm, 300 K 2 atm, 150 K 0.5 atm, 600 K 1 atm, 500 K . 16. Which of the following metals is present in brass, bronze and german silver ? Defence Mechanism Hydrolysis of ATP Trifling of Contraction Generating right electrical potential across cell membrane . 17. First ionization potential is ___________ second ionization potential. Less than More than Equal to None of these 18. n-propyl benzene is best prepared by Friedel-Crafts Reaction Wurtz Reaction Wurtz-Fitting Reaction Grignard Reaction 19. Chloroform is slowly oxidized by air to Formly Chloride Carbonyl Chloride Trichloroacetic Acid Formic Acide 20. Electrophoresis is Movement of colloidal particle under the influence of electric field Movement of colloidal particle under the influence of magnetic field Movement of colloidal particle in zig-zag fashion Scattering of light by colloidal particles 21. Rosenmund's reduction of an acyl chloride gives Alcohol Ester Hydrocarbon Aldehyde . 22. Pyrophosphoric acid is Monobasic Dibasic Tribasic Basic . 23. Which of the following is an example of a mathematical model ? Area of a circle = PI x Radius^2 Volume of a cube = Length^3 Force = Mass x Acceleration All of the above . 24. The specific activity of an enzyme is relatively constant between pH 3-8. If the enzyme activity at pH 7.0 is to be modeled, which of the following would be a reasonable simplifying assumption ? Specific activity is not dependent on temperature Specific activity is not dependent on substrate concentration Specific activity is not dependent on pH All of the above . 25. The bioreactor which is most commonly used in industry is the Batch Fermenter Fed Batch Fermenter Continous Fermenter Batch Continous Fermenter . 26. Which of the following is correct with regards to microbial growth ? Cells are autocatalysts and thus the rate of increase in biomass (dX/dt) keeps changing Many factors affect cell growth The rate of increase in biomass concentration is not constant during a fermentation All of the above are correct . 27. During a batch fermentation, when would the specific growth rate be lowest ? During exponential phase During the lag and stationary phase When cells are growing at their fastest rate Throughout the fermentation . 28. Which of the following describes a limitation of the exponential growth model ? Biomass growth is assumed to be not linked to the availability of nutrients or substrates It does not predict when cell growth will cease It predicts that all types of cells under all conditions will grow exponentially All of the above are correct . 29. In large scale bioreactors, dissolved oxygen levels are often so low that they restrict the rate of cell growth. In this case Dissolved oxygen would be the growth limiting nutrient The nitrogen source would be the growth limiting nutrient The carbon source would be the growth limiting nutrient Dissolved oxygen levels would not be the growth limiting nutrient . 30. Which of the following is not correct ?
