Geology QUESTION #10638

Question 2

A black or very dark coloured soil most strongly indicates an abundance of:

Sandstone fragments
Iron minerals
Clay minerals
Organic (humus) content✔️

Correct Answer Logic:

Black-coloured soils are characteristically rich in organic matter (humus) derived from decayed plant and animal material. High humus content gives soils their characteristic dark colour, improves water retention, nutrient availability, and soil structure. Examples include chernozems (black earth) of the Ukrainian steppes and regur (black cotton soil) of the Deccan Plateau, India. Iron minerals produce reddish-brown (oxidised) to grey-green (reduced) colours.

Question 3

In the photosynthesis process, how many ATP molecules are consumed in the synthesis of each glucose molecule?

18 ATP✔️
10 ATP
8 ATP
6 ATP

Correct Answer Logic:

The Calvin cycle (dark reactions) requires 18 ATP and 12 NADPH to fix 6 molecules of $CO_2$ into one glucose molecule: $6CO_2 + 18ATP + 12NADPH \to C_6H_{12}O_6 + 18ADP + 12NADP^+$. Each turn of the cycle uses 3 ATP and 2 NADPH; 6 turns are needed for one glucose.

Accounting & Finance QUESTION #6076

Question 4

Iga suspects that some credit notes received from suppliers have not been recorded. Which of the following actions should she take to verify this?

Compare purchases ledger balances against supplier statements
Extract a trial balance of individual purchases ledger accounts
Prepare a purchases ledger control account

1 and 2
1 only✔️
2 and 3 only
3 only

Correct Answer Logic:

Comparing the business's records with the supplier's statement is the most effective way to find missing credit notes, as the supplier will have recorded the credit note even if the business forgot to. A trial balance or control account only checks internal consistency.

Education QUESTION #6904

Question 5

Which of the following BEST characterizes the difference between 'primary prevention,' 'secondary prevention,' and 'tertiary prevention' in the context of school violence control?

Primary targets all students; secondary targets teachers; tertiary targets parents
Primary prevents problems from emerging through curriculum design; secondary provides tailored interventions for at-risk students; tertiary delivers intensive wraparound services for the most severely at-risk✔️
Primary uses counseling; secondary uses suspension; tertiary uses expulsion
Primary is annual; secondary is termly; tertiary is weekly

Correct Answer Logic:

These three levels of violence prevention form a tiered intervention model. Primary prevention is universal and proactive — embedding anti-violence principles in the curriculum for all students. Secondary prevention is selective — targeting students showing early at-risk indicators. Tertiary prevention is intensive — providing comprehensive, multi-agency support for students with severe behavioral and social challenges.

MBBS QUESTION #10310

Question 6

A patient with cirrhosis develops hypoalbuminemia and peripheral edema. Albumin's principal biochemical contributions to plasma include:

Maintaining plasma oncotic (colloid osmotic) pressure and acting as a carrier protein for bilirubin, drugs, hormones, and fatty acids✔️
Carrying oxygen in the bloodstream
Functioning primarily as a clotting factor
Serving as the major circulating immunoglobulin

Correct Answer Logic:

As the most abundant plasma protein, albumin generates most of plasma's oncotic pressure (retaining fluid within the vasculature) and serves as a nonspecific carrier for numerous poorly water-soluble substances; hypoalbuminemia from impaired hepatic synthesis in cirrhosis reduces oncotic pressure, contributing to edema/ascites.

Civil Engineering QUESTION #6608

Question 7

In plastic analysis of steel structures, the 'Shape Factor' of a cross-section is defined as the ratio of:

Elastic Section Modulus ($S$) to Plastic Section Modulus ($Z$)
Plastic Section Modulus ($Z$) to Elastic Section Modulus ($S$)✔️
Moment of Inertia ($I$) to Radius of Gyration ($r$)
Yield Stress ($F_y$) to Ultimate Stress ($F_u$)

Correct Answer Logic:

The Shape Factor $f = Z/S$. It represents the reserve strength of a section between the first yield and the formation of a plastic hinge.

Medicinal Chemistry and Biopharmaceutics QUESTION #3816

Question 8

Wool fat is unavailable and must be replaced by lanolin ($28\%$ water, $72\%$ wool fat). What amounts of lanolin and water are needed for the prescription: zinc oxide $2$ g, calamine $2$ g, wool fat $36$ g, water to $60$ g?

$34$ g lanolin and $22$ mL water
$40$ g lanolin and $16$ mL water
$46$ g lanolin and $10$ mL water
$50$ g lanolin and $6$ mL water✔️

Correct Answer Logic:

Lanolin needed $= \dfrac{36}{0.72} = 50$ g. Water from lanolin $= 50 \times 0.28 = 14$ mL. Total water in formula $= 60 - 2 - 2 - 36 = 20$ mL. Additional water $= 20 - 14 = 6$ mL.

Mathematics QUESTION #6021

Question 10

The system $x+ky+3z=0$, $3x+ky-2z=0$, $2x+4y-3z=0$ has a non-zero solution $(x,y,z)$. Find the value of $\dfrac{xz}{y^2}$.

-30
30
-10
10✔️

Correct Answer Logic:

For non-zero solution, $\Delta=0$:

$\begin{vmatrix}1&k&3\\3&k&-2\\2&4&-3\end{vmatrix}=1(−3k+8)−k(−9+4)+3(12−2k)=−3k+8+5k+36−6k=44−4k=0$

So $k=11$.

With $k=11$: from equations 1 and 2: $x+11y+3z=0$ and $3x+11y-2z=0$. Subtracting: $2x-5z=0\Rightarrow x=\frac{5z}{2}$.

Substituting back: $\frac{5z}{2}+11y+3z=0\Rightarrow 11y=-\frac{11z}{2}\Rightarrow y=-\frac{z}{2}$.

$\frac{xz}{y^2}=\frac{\frac{5z}{2}\cdot z}{\frac{z^2}{4}}=\frac{\frac{5z^2}{2}}{\frac{z^2}{4}}=\frac{5}{2}\times4=\mathbf{10}$

Mathematics QUESTION #1329

Question 11

The wave equation $u_{xx}=\dfrac{1}{c^2}u_{tt}$ describes waves that travel at speed:

1
$c$✔️
$c^2$
$\dfrac{1}{c}$

Correct Answer Logic:

The wave equation $u_{xx}=\dfrac{1}{c^2}u_{tt}$ has solutions of the form $f(x\pm ct)$, representing waves propagating in the $\pm x$ direction with speed $c$. The constant $c$ is the wave speed (e.g., for a string, $c=\sqrt{T/\mu}$).

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11125

Question 12

In the evolution of modern humans (Homo sapiens) from ancestors, the most significant evolutionary trend is:

Increasing cranial capacity✔️
Development of upright posture
Shortening of jaws
Development of binocular vision

Correct Answer Logic:

The most significant trend in human evolution is the dramatic increase in cranial capacity (brain size) — from ~450 cm³ in Australopithecus to ~1350–1500 cm³ in modern Homo sapiens. This expansion of the neocortex enabled language, abstract reasoning, tool use, social organisation, and cultural transmission — the defining features of humanity. Upright posture evolved earlier (in Australopithecus); binocular vision is a primate trait; jaw reduction is a consequence of dietary changes and reduced dentition.
