Question 4
The period of $3\cos\dfrac{x}{5}$ is:
Correct Answer Logic:
The period of $\cos(bx)$ is $\dfrac{2\pi}{|b|}$. Here $b = \dfrac{1}{5}$, so the period of $3\cos\dfrac{x}{5}$ is $\dfrac{2\pi}{1/5} = 10\pi$.

Correct Answer Logic:
In Selye's General Adaptation Syndrome (GAS), the Exhaustion stage is the third and final stage, occurring when prolonged stress has depleted the body's adaptive resources. The immune system weakens, and the individual becomes highly susceptible to disease, physical breakdown, and even death. The three stages are: (1) Alarm (initial 'fight or flight'), (2) Resistance (coping and adaptation), and (3) Exhaustion (resource depletion).

Question 8
What is the primary milk compositional factor that MOST significantly reduces heat stability?
Correct Answer Logic:
Ionic calcium concentration is the most critical factor affecting milk heat stability. Excess \(\text{Ca}^{2+}\) destabilizes casein micelles under heat by reducing surface charge and promoting cross-linking. Maximum heat stability occurs at \(\text{pH}\;6.7\text{β}6.9\) for UHT.

Lattice enthalpy is always:
Correct Answer Logic:
Lattice enthalpy (lattice dissociation energy) is defined as the energy required to completely separate one mole of a solid ionic compound into its gaseous ions. Since energy must be absorbed to overcome the strong electrostatic attractions, lattice enthalpy is always positive (endothermic). Lattice formation enthalpy (reverse process) is always negative.
