Math Physics Chemistry Biology QUESTION #11410

Enzymatic portion of the gastric juice secreted by gastric mucosa called:

Chief cell✔️
Parietal cell
G cells
Mucus cells

Correct Answer Logic:

Chief cells (zymogenic cells) in the gastric glands of the stomach secrete pepsinogen (inactive precursor of pepsin) and gastric lipase. Pepsinogen is activated to pepsin by HCl. Parietal cells secrete HCl and intrinsic factor; G cells secrete gastrin; mucus cells secrete protective mucus.

Biology QUESTION #7237

Question 3162

The thalloid body of a slime mould (Myxomycetes) is known as:

Fruiting body
Mycelium
Protonema
Plasmodium✔️

Correct Answer Logic:

In slime moulds (Myxomycetes), the vegetative body is a plasmodium — a multinucleate, acellular mass of protoplasm that moves and engulfs food. It is not a true mycelium (fungal hyphae network) nor a protonema (moss juvenile stage).

Accounting & Finance QUESTION #6135

Question 3163

A trial balance had a suspense account with a credit balance of $1,720. Errors found: (1) Purchases returns balance of $440 omitted from trial balance; (2) Bank overdraft balance understated by $90. What is the updated credit balance of the suspense account?

$1,190
$1,370
$2,070✔️
$2,250

Correct Answer Logic:

Option C ($2,070) is correct.

Error 1: Purchases returns (credit balance) omitted → credit total understated → Credit suspense $440.

Error 2: Bank overdraft (credit balance) understated → Credit suspense $90.

Updated balance = $1,720 + $440 − $90 = $2,070

Question 3164

What is the radius of convergence of the Maclaurin series for $f(z) = z^2 e^{3z}$?

$1$
$3$
$\infty$ (entire function)✔️
$\frac{1}{3}$

Correct Answer Logic:

$e^{3z}$ is entire (converges everywhere). Multiplying by $z^2$ preserves this property. Radius of convergence is $\infty$.

Academic/Professional (Social Sciences) QUESTION #10146

Question 3166

If a government reduces school fees but enrolment still stagnates due to child labour demands at home, this best illustrates that:

Economic policy alone determines enrolment
Structural/systemic socio-economic forces beyond fees also constrain education access✔️
Education policy is irrelevant to enrolment
Fees are the only barrier to enrolment

Correct Answer Logic:

This shows enrolment is shaped by broader socio-economic constraints, not fees alone.

MBBS QUESTION #10147

Question 3167

A 50-year-old man sustains a mid-shaft fracture of the femur. Radiographs at 6 weeks show a bridge of woven bone (external callus) at the fracture site. Which structure is primarily responsible for producing this bridging callus?

Periosteum✔️
Endosteum
Articular (hyaline) cartilage
Epiphyseal growth plate

Correct Answer Logic:

The inner (cambium) layer of the periosteum is richly osteogenic and proliferates rapidly after a fracture, laying down subperiosteal (external) callus that bridges the fracture ends. The endosteum contributes to internal callus formation, but bridging external callus is chiefly periosteal in origin — the basis for careful periosteal preservation during open fracture fixation.

Physics QUESTION #7039

Question 3168

In SI units, a material's density is $128 \text{ kg m}^{-3}$. Calculate its numerical value in a system where the unit of length is $25 \text{ cm}$ and the unit of mass is $50 \text{ g}$.

$40$✔️
$16$
$640$
$410$

Correct Answer Logic:

Using $n_1 u_1 = n_2 u_2$:

$128 \times [\text{kg} \cdot \text{m}^{-3}] = n_2 \times [(50 \text{ g}) \cdot (25 \text{ cm})^{-3}]$

$n_2 = 128 \times \left( \frac{1000 \text{ g}}{50 \text{ g}} \right) \times \left( \frac{25 \text{ cm}}{100 \text{ cm}} \right)^3$

$n_2 = 128 \times 20 \times \left( \frac{1}{4} \right)^3 = \frac{128 \times 20}{64} = 2 \times 20 = 40$.

Agriculture Economics QUESTION #11895

Question 3169

Market equilibrium occurs where:

Quantity supplied exceeds quantity demanded
Quantity demanded equals quantity supplied at the prevailing price, $Q_d = Q_s$✔️
Price equals average cost
Total revenue is maximized

Correct Answer Logic:

Equilibrium is the price-quantity point at which $Q_d = Q_s$: the quantities buyers wish to purchase and sellers wish to offer are exactly equal.

Mathematics QUESTION #4126

Question 3170

For $f(z) = \frac{1}{z} = \frac{\cos(\theta)}{r} - i\frac{\sin(\theta)}{r}$ in polar form, compute $u_r$ and verify C-R equations. What is $u_r$?

$-\frac{\cos(\theta)}{r^2}$✔️
$-\frac{1}{r^2}$
$\frac{\cos(\theta)}{r}$
$\frac{1}{r}$

Correct Answer Logic:

$u = \frac{\cos(\theta)}{r}$, so $u_r = -\frac{\cos(\theta)}{r^2}$. Also $v = -\frac{\sin(\theta)}{r}$, so $v_\theta = -\frac{\cos(\theta)}{r}$. Then $\frac{1}{r}v_\theta = -\frac{\cos(\theta)}{r^2} = u_r$. C-R satisfied.

The Constitution of Pakistan QUESTION #9341

Question 3171

A resolution for a vote of no-confidence against the Prime Minister must be moved by how many members, and must be voted on within what timeframe?

One-third of total membership; within three to ten days
Not less than twenty percent of total membership; not before three days and not later than seven days✔️
Not less than one-fourth of total membership; within five days
A majority of total membership; within forty-eight hours

Correct Answer Logic:

Article 95(1) requires at least 20% of total membership to move the resolution. Article 95(2) mandates the vote cannot be held before three days, nor later than seven days, from the day the resolution is moved — preventing both rushed removal and indefinite delay.

Civil Engineering QUESTION #6630

Question 3173

The 'effective flange width' of a T-beam is limited primarily to account for:

Shear lag effects✔️
Concrete shrinkage
Torsional stiffness
The weight of the slab

Correct Answer Logic:

The flange of a T-beam does not experience uniform stress across its entire width due to shear lag; hence, an 'effective' width is used for design calculations.

Nursing QUESTION #9189

Question 3174

According to Florence Nightingale's Environmental Theory, which of the following is the PRIMARY focus of nursing care?

Administering medications as prescribed by the physician
Manipulating the patient's environment to facilitate natural healing✔️
Building a therapeutic nurse-patient relationship
Teaching patients about disease pathophysiology

Correct Answer Logic:

Correct Answer: B

Florence Nightingale's Environmental Theory (1860) was the first formal nursing theory. Its core premise is that nursing's role is to manipulate the environment to place the patient in the best condition for nature to act and heal.

Key environmental factors Nightingale identified:

Fresh air and ventilation
Clean water
Efficient drainage
Cleanliness
Light (especially sunlight)
Noise reduction

This theory laid the foundation for infection control and evidence-based environmental management in nursing practice.

Boilers Mechanical Engineering QUESTION #2518

Question 3179

The principle of work and energy for a particle states that the net work done by all forces equals:

The change in potential energy only
The change in kinetic energy: $U_{1\to2}=\frac{1}{2}mv_2^2 - \frac{1}{2}mv_1^2$✔️
The impulse of the net force
The product of average force and displacement

Correct Answer Logic:

Work-energy theorem: $U_{1\to2}=T_2-T_1$, where $T=\frac{1}{2}mv^2$ is kinetic energy. This is derived by integrating Newton's second law along the path.

Law QUESTION #9533

Question 3180

A suit for recovery is decreed in A's favour. B appeals to the District Court. The District Court dismisses the appeal. B files a second appeal to the High Court. The High Court does not formulate a substantial question of law at the time of admission. Judgment is delivered by the High Court in the second appeal. B argues that failure to formulate the substantial question of law at admission is a fatal procedural defect. Is this argument correct?

No; formulation of the substantial question of law is optional
Yes; under Section 100 CPC, the High Court is required to formulate the substantial question of law at the time of admitting the second appeal, and the appeal must be heard on that question; failure to do so is a jurisdictional error that can vitiate the High Court's judgment✔️
Yes; but it only affects the costs of the appeal
No; the High Court can formulate the question at any stage including during judgment

Correct Answer Logic:

Section 100 CPC mandates that the High Court shall formulate the substantial question of law before admitting a second appeal, and the appeal is to be heard on the question so formulated. This is a mandatory procedural safeguard. Failure to formulate the question at admission and then deciding on a question not formulated is a procedural irregularity that can be challenged.
