Facilitated diffusion moves solutes down their concentration gradient using a specific membrane carrier, without direct ATP consumption, but unlike simple diffusion it is saturable and carrier-specific — the mechanism used by most glucose transporters (GLUTs) in peripheral tissues.

Question 8

The ester formed from a fatty acid and a long-chain alcohol is called:

Acylglycerol

Agronomy QUESTION #2018

Question 11

Minimum tillage is advocated in modern agronomy primarily because it:

Increases soil compaction which improves root anchorage
Reduces soil erosion, preserves organic matter, lowers fuel costs, and maintains soil biotic activity✔️
Completely eliminates the need for herbicide application
Increases soil bulk density to improve water retention

Correct Answer Logic:

Minimum tillage (conservation tillage) reduces the number and intensity of tillage operations. This conserves soil structure, reduces erosion, maintains soil organic matter and microbial activity, and significantly reduces labor and fuel costs — central to sustainable crop production.

Question 12

The primary difference between a Syrup and an Elixir is:

Syrups are always alcoholic
Elixirs are less sweet and less viscous than syrups✔️
Syrups contain no water
Elixirs are only for external use

Correct Answer Logic:

Elixirs contain alcohol for solubility and are typically less viscous than sucrose-heavy syrups.

Chemistry QUESTION #7167

Question 13

Under what specific conditions can the Tyndall effect be clearly observed?

Particle diameter is much smaller than the wavelength; refractive indices are similar
Particle diameter is not much smaller than the wavelength; refractive indices are similar
Particle diameter is much smaller than the wavelength; refractive indices differ significantly
Particle diameter is not much smaller than the wavelength; refractive indices differ significantly✔️

Correct Answer Logic:

The Tyndall effect is the scattering of light by colloidal particles. It is observed only when:

The diameter of the dispersed particles is not much smaller than the wavelength of light used.
The refractive indices of the dispersed phase and the dispersion medium differ greatly in magnitude.

Law QUESTION #9489

Question 14

A files a suit claiming ownership of a well-defined plot. The Court, after hearing both sides, finds in favour of A on all issues but inadvertently omits to grant consequential relief of mesne profits although it was claimed in the plaint. A applies for amendment of the decree. B argues the decree is final and cannot be amended. What should the Court do?

Refuse; a decree once passed is final and cannot be amended
Allow A's application; the Court has power under Section 152 to correct clerical or arithmetical mistakes and accidental omissions in decrees, and under the inherent powers of Section 151 in appropriate cases✔️
Direct A to file a fresh suit for mesne profits
Refer the matter to the High Court

Correct Answer Logic:

Section 152 CPC empowers the Court to correct clerical or arithmetical mistakes in judgments, decrees or orders, or errors arising from accidental slips or omissions. The inadvertent omission of a claimed relief that was argued falls within correctable error. Additionally, Section 151 preserves inherent powers to do justice.

Agronomy QUESTION #2042

Question 15

Vermicompost differs from conventional FYM in that:

It has lower nutrient content and slower release rates
It is processed through earthworm digestion, resulting in finer particle size, higher microbial activity, better nutrient availability, plant growth hormones, and humic acids compared to conventional composting✔️
It can only be applied as a liquid foliar spray
It increases soil acidity more rapidly than FYM

Correct Answer Logic:

Earthworms (Eisenia fetida) physically and biochemically transform organic matter during vermicomposting. The product has higher N (1.5–2.5%), better C:N ratio, richer microbial diversity, plant hormones (auxins, gibberellins), humic/fulvic acids, and finer texture than FYM — resulting in better crop response per unit weight applied.

Psychology QUESTION #9877

Question 17

Which of the following tests is likely to have the highest reliability?

The TAT
The Rorschach
The MMPI✔️
The Draw-a-Person tests

Correct Answer Logic:

The MMPI is an objective, standardized personality test with well-established high reliability. Projective tests (TAT, Rorschach, Draw-a-Person) rely on subjective interpretation, producing lower inter-rater and test-retest reliability.

Verbal Reasoning QUESTION #8099

Question 18

The circumference of circle $C$ is $18\pi$.

Compare:

Column A: The diameter of circle $C$

Column B: $9$

Column A is greater✔️
Column B is greater
The two quantities are equal
The relationship cannot be determined from the information given

Correct Answer Logic:

The circumference formula is $C = \pi d$, where $d$ is the diameter.

$18\pi = \pi d \Rightarrow d = 18$

Column A = 18, Column B = 9.

Since $18 > 9$, Column A is greater.

Chemistry QUESTION #4359

Question 20

The order of ease of reduction of $H^{+1}$, $Cu^{+2}$, and $Ag^{+1}$:

$H^{+1} > Cu^{+2} > Ag^{+1}$
$H^{+1} > Ag^{+1} > Cu^{+2}$
$Ag^{+1} > Cu^{+2} > H^{+1}$✔️
$H^{+1} > Cu^{+2} = Ag^{+1}$

Correct Answer Logic:

Ease of reduction follows the standard reduction potential (SRP): $Ag^{+}/Ag = +0.80\ V$, $Cu^{2+}/Cu = +0.34\ V$, $H^{+}/H_2 = 0.00\ V$. Higher SRP = easier to reduce. Order: $Ag^{+1} > Cu^{+2} > H^{+1}$.
