MBBS QUESTION #10224

In an adult, erythropoietin — the principal hormonal driver of red blood cell production — is synthesized mainly by which cells?

Bone marrow stromal cells
Hepatocytes
Peritubular interstitial cells of the kidney✔️
Splenic red pulp macrophages

Correct Answer Logic:

The peritubular interstitial cells of the renal cortex sense local tissue oxygen tension and are the principal source of erythropoietin in adults (the liver contributes more in fetal life); this is why chronic kidney disease characteristically produces anemia via reduced erythropoietin production.

Civil / Architecture QUESTION #2368

Question 5

In the context of Building Management Systems (BMS) for integrated building design, SCADA refers to:

Structural Control and Design Automation — a software for automated RC design
Supervisory Control and Data Acquisition — a system for real-time monitoring and control of building services (HVAC, electrical, fire, security)✔️
Sustainable Construction and Design Assessment — a green building rating tool
System for Computer-Aided Drafting and Architecture — a CAD platform for BIM

Correct Answer Logic:

SCADA (Supervisory Control and Data Acquisition) is a control system architecture used in BMS that enables real-time monitoring, data acquisition, and supervisory control of building systems including HVAC, lighting, electrical distribution, fire suppression, and security. It typically consists of field devices (sensors, actuators), PLCs/RTUs, a communication network, and an HMI (Human-Machine Interface) for operators.

Psychology QUESTION #1462

Question 7

Which theory of emotion suggests that emotions occur simultaneously with physiological reactions?

Cannon-Bard Theory✔️
Schachter-Singer Two-Factor Theory
James-Lange Theory
Lazarus Cognitive-Mediational Theory

Correct Answer Logic:

The Cannon-Bard Theory (Walter Cannon and Philip Bard, 1927) proposes that emotions and physiological responses occur simultaneously and independently — both triggered at the same time by the thalamus. James-Lange Theory proposes emotions follow physiological arousal; Schachter-Singer requires cognitive labelling of arousal; Lazarus's theory emphasises cognitive appraisal as the primary step before emotion.

Civil Engineering QUESTION #6589

Question 8

In a reinforced concrete member under applied loading, if the steel reaches its maximum (yield) stress before the concrete reaches its limiting compressive strain, the section is classified as:

Over-reinforced section
Balanced section
Under-reinforced section✔️
None of the above

Correct Answer Logic:

An under-reinforced section has less steel than the balanced condition. Steel yields first, providing ductile failure with large deflections as warning before the concrete crushes.

Boilers Mechanical Engineering QUESTION #2417

Question 11

The thermal diffusivity $\alpha$ is defined as:

$\alpha = \rho c / k$
$\alpha = k / (\rho c)$✔️
$\alpha = k \cdot \rho \cdot c$
$\alpha = k / c$

Correct Answer Logic:

Thermal diffusivity $\alpha=k/(\rho c)$ (m²/s) characterizes how quickly a material responds to temperature changes. High $\alpha$ means faster thermal response.

Geography QUESTION #6308

Question 13

The Keeling Curve showing atmospheric CO2 concentration exhibits annual oscillations primarily due to:

Seasonal variation in fossil fuel combustion
Northern Hemisphere vegetation seasonal photosynthesis and respiration cycles✔️
Ocean temperature-driven CO2 solubility changes
Volcanic activity fluctuations

Correct Answer Logic:

Annual oscillations in the Keeling Curve (~5-7 ppm amplitude) result from seasonal vegetation cycles in the Northern Hemisphere where most land mass exists. During NH summer, photosynthesis removes CO2; during winter, respiration and decomposition release it.

Chemistry QUESTION #5532

Question 17

For a reaction following the Arrhenius equation, the plot of $\ln k$ vs $\frac{1}{RT}$ gives a straight line with slope $(-y)$ units. The activation energy of the reaction is:

$y/R$ units
$y$ units✔️
$yR$ units
$-y$ units

Correct Answer Logic:

Arrhenius equation: $\ln k = \ln A - \frac{E_a}{RT}$. Plotting $\ln k$ vs $\frac{1}{RT}$, the slope = $-E_a$. Given slope = $-y$, therefore $E_a = y$ units. (Note: if plotted against $\frac{1}{T}$, slope = $-E_a/R$, but here the x-axis is $\frac{1}{RT}$, so the R is already incorporated into the x-axis, making the slope directly equal to $-E_a$.)

Law QUESTION #9510

Question 18

A judgment is pronounced by the trial Court on 1 March 2023. The formal decree is drawn up and signed on 15 April 2023. An appeal is filed on 25 March 2023, i.e., after judgment but before the formal decree. The respondent contends the appeal is premature and incompetent. Is this objection valid?

No; the appellate Court should wait until the formal decree is ready before hearing the appeal
No; under Section 96 CPC, an appeal lies from a decree, and the date of the decree is the date of the judgment; the formal decree, once drawn, relates back to the date of the judgment. An appeal filed after judgment but before formal drawing of the decree is valid✔️
Yes; an appeal can only be filed after the decree is formally drawn up and signed
Yes; limitation for appeal runs from the date the decree is signed

Correct Answer Logic:

Section 2(2) CPC defines a decree as a formal expression of adjudication. A decree relates to the judgment which precedes it. Under Order XX CPC, the decree follows from the judgment. Limitation for appeal runs from the date of decree (i.e., the date of judgment). An appeal filed after judgment is not premature even if the formal decree has not been drawn.

Chemistry QUESTION #7387

Question 20

Among the isoelectronic species $\text{O}^{2-}$, $\text{F}^-$, $\text{Na}^+$, $\text{Mg}^{2+}$ and $\text{Al}^{3+}$, their ionic radii show which trend?

An increase from $\text{O}^{2-}$ to $\text{F}^-$ then decrease from $\text{Na}^+$ to $\text{Al}^{3+}$
A decrease from $\text{O}^{2-}$ to $\text{F}^-$ then increase from $\text{Na}^+$ to $\text{Al}^{3+}$
A significant overall increase from $\text{O}^{2-}$ to $\text{Al}^{3+}$
A significant overall decrease from $\text{O}^{2-}$ to $\text{Al}^{3+}$✔️

Correct Answer Logic:

Isoelectronic species all have 10 electrons. Their size depends on nuclear charge:

$\text{O}^{2-}(Z=8) > \text{F}^-(Z=9) > \text{Na}^+(Z=11) > \text{Mg}^{2+}(Z=12) > \text{Al}^{3+}(Z=13)$

More protons = stronger pull on same electron cloud = smaller radius. There is a steady significant decrease across the series. No increase occurs — all species have the same number of electrons but increasing nuclear charge.
