Question 2761

If $0 < x < 1$, which is largest?

$x$
$x^2$
$\sqrt{x}$✔️
All equal

Correct Answer Logic:

For $0 < x < 1$: $x^2 < x < \sqrt{x}$. Example: if $x = 0.25$, then $x^2 = 0.0625$, $x = 0.25$, $\sqrt{x} = 0.5$

Question 2763

The phase of mitosis in which chromosomes align at the cell's equator is called:

Anaphase
Telophase
Metaphase✔️
Prophase

Correct Answer Logic:

During metaphase (the middle phase of mitosis), chromosomes become maximally condensed and are aligned along the cell's equatorial plane (metaphase plate) by spindle fibres attached to the centromeres (kinetochores). This alignment ensures accurate segregation of sister chromatids to the two daughter cells in the subsequent anaphase.

Question 2764

The phenomenon of lactose crystallization in concentrated milk products causing a gritty texture is called:

Syneresis
Maillard browning
Sandiness due to $\alpha$-lactose monohydrate crystal formation (crystals $>30\;\mu\text{m}$)✔️
Creaming

Correct Answer Logic:

When lactose supersaturation occurs in condensed or sweetened condensed milk or ice cream, large $\alpha$-lactose monohydrate crystals ($>30\;\mu\text{m}$) form causing sandiness or grittiness. Control involves rapid cooling, seeding with fine lactose crystals, or use of lactase.

Chemistry QUESTION #5534

Question 2765

Sucrose undergoes acid hydrolysis via first-order kinetics with a half-life of 3.33 h at 25°C. After 9 h, the fraction of sucrose remaining is $f$. Find the value of $\log_{10}\!\left(\dfrac{1}{f}\right)\times10^{-2}$ (nearest integer). [Given: $\ln 10 = 2.303$, $\ln 2 = 0.693$]

81✔️
90
135
27

Correct Answer Logic:

$k = \frac{0.693}{3.33} = 0.208\ h^{-1}$. After $t=9$ h: $\ln\left(\frac{1}{f}\right) = kt = 0.208\times9 = 1.872$. $\log_{10}\left(\frac{1}{f}\right) = \frac{1.872}{2.303} = 0.8127$. Answer $= 0.8127\times10^{-2}\times10^{2}\approx81\times10^{-2}$, so the value is $\approx 81\times10^{-2}$, meaning the answer = 81.

Physics QUESTION #4405

Question 2767

If the surface charge density of an infinite sheet increases by $25\%$, the electric field intensity:

Increases by $25\%$✔️
Increases by $50\%$
Decreases by $25\%$
Remains the same

Correct Answer Logic:

Electric field due to an infinite sheet: $E = \dfrac{\sigma}{2\varepsilon_0}$. Since $E \propto \sigma$ (direct proportion), if $\sigma$ increases by $25\%$, then $E$ also increases by $25\%$.

The Constitution of Pakistan QUESTION #9391

Question 2769

The Supreme Court's appellate jurisdiction under Article 185 after the 27th Amendment is now expressly made subject to Article 175F. What is the primary significance of this subjection?

Supreme Court retains concurrent appellate jurisdiction
Matters involving constitutional questions on High Court Article 199 orders now go to the Federal Constitutional Court under Article 175F, not directly to the Supreme Court✔️
The Supreme Court can no longer hear criminal appeals
Appeals from family courts now go to the FCC

Correct Answer Logic:

Article 185(1) as substituted by the 27th Amendment provides that the Supreme Court's appellate jurisdiction is 'subject to this Article and Article 175F.' Article 175F grants the FCC appellate jurisdiction over High Court orders under Article 199 involving constitutional questions. Article 185(3) now adds a proviso that no appeal shall lie to the Supreme Court in cases where Article 175F applies — creating a clean jurisdictional division.

Pharmacokinetics and Pharmacodynamics QUESTION #3834

Question 2775

A drug undergoing first-order hydrolysis has an initial concentration of $0.16$ M, which falls to $0.04$ M after $6$ days. What is its half-life?

$1$ day
$2$ days
$3$ days✔️
$4$ days

Correct Answer Logic:

$0.16 \rightarrow 0.08$ M (one half-life) $\rightarrow 0.04$ M (two half-lives). Two half-lives $= 6$ days, therefore half-life $= 3$ days.

Question 2776

Which defect in butter is caused by oxidation of unsaturated fatty acids resulting in fishy or tallowy off-flavors?

Rancidity due to lipolysis
Oxidative rancidity due to lipid peroxidation of phospholipids and unsaturated fatty acids (oleic C18:1, linoleic C18:2, linolenic C18:3)✔️
Microbial putrefaction producing $\text{H}_2\text{S}$
Excessive salt crystallization

Correct Answer Logic:

Oxidative rancidity in butter results from peroxidation of unsaturated fatty acids and phospholipids, forming aldehydes, ketones, and other volatiles giving tallowy, painty, or fishy notes. It is initiated by light, metals (Cu, Fe), and $\text{O}_2$. Antioxidants and light-proof packaging provide control.
