Geography QUESTION #1249

Question 2

Natural levees are associated with:

Alluvial fans
Flood plains✔️
Deltas
None of these

Correct Answer Logic:

Natural levees are low ridges of alluvial sediment built up along the banks of a river, formed when floodwaters overflow and deposit their heaviest sediment load immediately adjacent to the channel. They are characteristic features of flood plains. As the river repeatedly floods, these ridges grow higher and help confine the river channel.

Question 3

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

$x$
$x^2$

All equal

Correct Answer Logic:

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

Accounting & Finance QUESTION #6082

Question 7

A trader provided the following data:

Item	Jan 1 ($)	Dec 31 ($)
Bank (Debit)	4,240	6,320
Cash balance	264	271

During the year: Cheques issued were $19,950. All sales takings were banked except for $5,400 used for drawings and $7,200 for wages. Additionally, $3,000 was banked from the sale of a motor vehicle. Calculate total sales.

$22,037
$31,630
$31,637✔️
$34,637

Correct Answer Logic:

1. Cash banked from sales = Closing Bank ($6,320) + Cheques issued ($19,950) - Opening Bank ($4,240) - Sale of Asset ($3,000) = $19,030.
2. Total Sales = Banked Sales ($19,030) + Cash Drawings ($5,400) + Cash Wages ($7,200) + (Closing Cash $271 - Opening Cash $264) = $19,030 + $5,400 + $7,200 + $7 = $31,637.

Agronomy QUESTION #2080

Question 8

Pre-emergence herbicides are most effective when:

Applied to the soil surface just before crop harvest
Applied to the soil surface before weed seeds germinate and seedlings emerge, requiring activation by rainfall or irrigation to move into the germinating weed seed zone where they disrupt seedling growth✔️
Applied to fully emerged weed foliage using directed spraying
Mixed with foliar fertilizers to improve weed control

Correct Answer Logic:

Pre-emergence herbicides act on germinating seeds in the soil — they must be incorporated into the top 2–5 cm of the germination zone by rainfall or irrigation (activation) to contact the target weed. They form a chemical barrier disrupting cell division or pigment synthesis in germinating seedlings. Dry, crusted soil surfaces, delayed activation, and deep-plowed weed seeds reduce their efficacy.

MBBS QUESTION #10279

Question 13

Bilateral destructive lesions of the ventromedial nucleus of the hypothalamus (the 'satiety center') classically result in:

Hyperphagia and progressive obesity, due to loss of the normal satiety signal✔️
Severe anorexia and weight loss
Complete abolition of the thirst sensation
Permanent hypothermia with no effect on appetite

Correct Answer Logic:

The ventromedial hypothalamic nucleus normally signals satiety and inhibits further feeding; its destruction removes this 'stop eating' signal, producing unchecked hyperphagia and obesity — the opposite effect to lesions of the lateral hypothalamic ('feeding center'), which cause aphagia.

Chemistry QUESTION #1086

Question 15

Sugar 'X': A. is found in honey. B. is a keto sugar. C. exists in $\alpha$ and $\beta$-anomeric forms. D. is laevorotatory. 'X' is:

Maltose
Sucrose
D-Glucose
D-Fructose✔️

Correct Answer Logic:

D-Fructose satisfies all conditions: (A) Found in honey — ✓. (B) Keto sugar (ketohexose) — ✓. (C) Exists in $\alpha$ and $\beta$-anomeric forms (in cyclic pyranose/furanose forms) — ✓. (D) Laevorotatory (rotates plane of polarized light to left, hence the 'D' prefix refers to configuration, not optical rotation) — ✓. D-Glucose is dextrorotatory.

Education QUESTION #10858

Question 16

SOLO Taxonomy provides a systematic way of describing a learner's:

Ability
Understanding✔️
Performance
Skill

Correct Answer Logic:

SOLO Taxonomy (Structure of Observed Learning Outcomes), developed by Biggs and Collis (1982), describes the quality of a learner's understanding of a topic through five increasingly complex levels: prestructural, unistructural, multistructural, relational, and extended abstract. It helps teachers assess how well students understand (depth and complexity), not merely whether they know facts. It is used for designing assessments and providing qualitative feedback.

Chemistry QUESTION #7500

Question 19

Which of the following compounds is the strongest acid?

$\text{CHBr}_3$
$\text{CHI}_3$
$\text{CH(CN)}_3$✔️
$\text{CHCl}_3$

Correct Answer Logic:

Acidity of $\text{CHX}_3$ compounds depends on the electron-withdrawing ability of the substituents X, which stabilize the conjugate base carbanion $\text{CX}_3^-$.

CN is an extremely strong electron-withdrawing group (by both induction and resonance).
$\text{CH(CN)}_3$ has three CN groups, creating maximum negative charge delocalization on the carbanion — giving the most stable conjugate base.
Halogens: electronegativity order is F > Cl > Br > I, so CHCl$_3$ > CHBr$_3$ > CHI$_3$ in acidity.

Overall: CH(CN)$_3$ is the strongest acid due to the powerful electron-withdrawing CN groups.
