Chemistry QUESTION #7382

Which atomic model described the atom as a sphere of uniform positive charge with electrons embedded in it to give a stable arrangement?

Thomson's atomic model✔️
Rutherford's atomic model
Bohr's atomic model
Chadwick's atomic model

Correct Answer Logic:

Thomson's 'plum pudding' model (1904) proposed that the atom is a sphere of diffuse positive charge with electrons embedded throughout like plums in a pudding. This model was disproved by Rutherford's gold foil experiment (1911), which showed that positive charge is concentrated in a tiny dense nucleus, with electrons orbiting at large distances.

Yamaman
Moota✔️
Tabook
Badr

Geography QUESTION #6307

Question 5303

Which environmental transformation represents the most significant anthropogenic modification of the nitrogen cycle?

Deforestation reducing nitrogen fixation by legumes
Haber-Bosch process creating reactive nitrogen for fertilizers✔️
Burning fossil fuels releasing NOx compounds

Correct Answer Logic:

The Haber-Bosch process (converting N2 to NH3 for fertilizers) has doubled the amount of reactive nitrogen entering the biosphere annually - the single largest human modification of the nitrogen cycle, exceeding all natural terrestrial nitrogen fixation combined.

Agronomy QUESTION #2062

Question 5304

In drip fertigation, urea is preferred over ammonium nitrate for nitrogen supply primarily because:

Urea has higher N content (46%) and remains soluble in irrigation water without precipitating or corroding drip emitters under normal conditions✔️
Ammonium nitrate is less soluble in water
Urea immediately converts to nitrate before entering drip lines
Ammonium nitrate causes salt injury to crops when fertigated

Correct Answer Logic:

Urea (46% N) is the most commonly fertigated N source because it is highly soluble (1080 g/L at 20°C), non-ionic (does not react with Ca, Mg, or carbonates in irrigation water to precipitate), and non-corrosive to metal emitters. Ammonium nitrate, while soluble, can react with hard water and poses explosion risk in storage.

General Knowledge QUESTION #11544

Question 5305

A standardised set of rules governing data transmission across the internet is called a:

IP address
Domain
Protocol✔️
Gateway

Correct Answer Logic:

Protocols are standardised sets of rules governing how data is transmitted, formatted, and received over a network. Key internet protocols: TCP/IP (data transmission), HTTP/HTTPS (web), FTP (file transfer), SMTP (email), DNS (name resolution), and TLS (security). Without protocols, devices cannot communicate reliably.

Question 5306

For how many years did the Caliphate of Hazrat Abu Bakr (R.A) last?

Two years✔️
Three years
Four years
Five years

Correct Answer Logic:

This is a repeat of questions 92 and 168. Hazrat Abu Bakr's (RA) caliphate lasted approximately 2 years and 3 months (11-13 AH / 632-634 CE). Despite the brief duration, his achievements were monumental: he maintained Muslim unity after the Prophet's death, fought and won the Ridda Wars against apostasy and false prophets, initiated the compilation of the Quran, and began the expansion of Islam into Syria and Iraq. He died at age 63 from natural causes.

Chemistry QUESTION #7125

Question 5308

Identify the absolute configuration ($R/S$) for the chiral centers at positions 2 and 3 in the following Fischer projection: $CO_{2}H$ at top, $H$ and $OH$ on C2, $H$ and $Cl$ on C3, and $CH_{3}$ at bottom.

$(2S, 3R)$✔️
$(2S, 3S)$
$(2R, 3R)$
$(2R, 3S)$

Correct Answer Logic:

At C2: Priority order is $-OH > -COOH > -C(H)(Cl)CH_3 > -H$. The sequence is counter-clockwise, but since $H$ is on the horizontal line, it is 2S.
At C3: Priority order is $-Cl > -CH(OH)COOH > -CH_3 > -H$. The sequence is clockwise, but with $H$ on the horizontal line, it is 3R.

Law QUESTION #9474

Question 5311

Plaintiff sued Defendant for Rs. 200,000 as arrears of rent. The defendant filed a written statement claiming a set-off of Rs. 150,000 for money lent to the plaintiff. The plaintiff argues a set-off can only relate to the same transaction. Should the Court allow the set-off?

Yes; under the CPC a legal set-off is permissible for any ascertained sum of money due from the plaintiff to the defendant, even if arising from a different transaction✔️
No; set-off requires a separate counter-claim and cannot be raised in the written statement
Yes; but only if the defendant had already demanded the money from the plaintiff before the suit
No; set-off is only permissible when it arises from the same transaction as the plaintiff's claim

Correct Answer Logic:

Order VIII Rule 6 CPC permits a defendant to claim a legal set-off for any ascertained sum of money legally recoverable from the plaintiff, regardless of whether the cross-claim arises from the same transaction. The Rs. 150,000 loan, being an ascertained and legally recoverable sum, qualifies as a valid set-off.

Civil Procedure QUESTION #5677

Question 5314

A plaintiff amends their complaint to add a new defendant after the statute of limitations has run. Under Rule 15(c)(1)(C), the amendment relates back if the new defendant received notice of the action within the period provided by Rule 4(m) and:

Knew or should have known the action would have been brought against it, but for a mistake concerning the proper party's identity.✔️
Is a subsidiary of the original defendant.
Suffered no prejudice from the delay.
Consents to the relation back.

Correct Answer Logic:

Rule 15(c)(1)(C) allows relation back when the party to be brought in knew or should have known that the action would have been brought against it, but for a mistake concerning identity.

Verbal Reasoning QUESTION #8073

Question 5315

Given that $|-\overline{3}| = -m$, compare:

Column A: $m$

Column B: 3

Column A is greater
Column B is greater
The two quantities are equal✔️
The relationship cannot be determined

Correct Answer Logic:

First, evaluate the left side: $|-\overline{3}| = |-3| = 3$

So we have: $3 = -m$

Solving for $m$: $m = -3$

Now compare:

Column A: $m = -3$
Column B: $3$

Since $-3 < 3$, Column B is greater.

Question 5317

Vertebrate photoreceptors undergo which change in response to a light stimulus?

Depolarization
Repolarization
Hyperpolarization✔️
Transduction

Correct Answer Logic:

Unlike most sensory receptors, vertebrate photoreceptors (rods and cones) hyperpolarize in response to light. In darkness, cGMP keeps Na⁺ channels open, keeping the cell relatively depolarized. Light activates rhodopsin → transducin → phosphodiesterase → cGMP breakdown → Na⁺ channels close → membrane hyperpolarizes. This hyperpolarization reduces glutamate release onto bipolar cells, ultimately signalling light detection.

Disaster Management QUESTION #6536

Question 5318

Which factor most critically determines the success of community-based disaster preparedness programs?

Amount of training provided
Community ownership through participatory planning, devolved resources, and decision-making authority✔️
Quality of training materials
Number of participants

Correct Answer Logic:

Sections 4.3 and 13.4 emphasize that community preparedness succeeds when communities have actual decision-making power, resources, and ownership. External training without local authority and resources creates dependency rather than sustainable resilience.
