Aptitude and Reasoning - Part 2

Which one of the following statements is INCORRECT with respect to food rheology?

In aptitude and reasoning, quantitative reasoning dictates that ratio, percentage and series logic determine correct calculation. Therefore Molten chocolate is a perfect Newtonian fluid is correct as it meets mathematical and logical criteria, supported by mechanistic studies and conserved across related systems.

Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.

Biochemistry and Aptitude and Reasoning

Cooking meat in presence of cut pieces of Papaya fruit results in unusually tender meat. What enzyme, present in the Pap

The principle of enzyme catalysis and lipid structure explains that substrate affinity, transition state stabilization and phospholipid composition govern function. Hence Papain fits best because it reflects catalytic efficiency and membrane organization, as documented in authoritative sources on biochemistry.

Ref: Lehninger Principles of Biochemistry, Chapter 9, Lipids and Membranes, explains phospholipid components, glycerol, fatty acids, phosphate group and membrane structure providing foundation for lipid biochemistry.

Electromagnetic Spectrum - Radio Waves and Microwaves

Why do microwaves heat food more effectively than infrared waves in domestic microwave ovens?

**Hertz experiment** produced radio waves using spark gap LC oscillator, detected with loop antenna, confirming Maxwell's prediction, frequency ≈10⁸ Hz, wavelength ≈3 m, demonstrating EM waves travel at c, transverse, can be reflected, refracted, polarized. Microwaves are tuned to the resonant frequency of water molecules, causing them to oscillate and generate heat via friction, whereas infrared waves primarily heat surfaces through absorption. Using c = fλ, E₀/B₀ = c, I_d = ε₀ dΦ_E/dt, and spectrum classification λ = c/f, evaluation yields Resonance with water molecules, illustrating EM wave
