Math Physics Chemistry Biology QUESTION #790

Question 2684

Molarity of heavy water $(\text{D}_2\text{O})$:

55.5 mol dm$^{-3}$
60.5 mol dm$^{-3}$
40.5 mol dm$^{-3}$
50.5 mol dm$^{-3}$✔️

Correct Answer Logic:

Molarity of heavy water $= \dfrac{\text{density} \times 1000}{\text{molar mass}} = \dfrac{1.105 \times 1000}{20} \approx 55.5$ mol dm$^{-3}$. Note: The paper marks 50.5 but the accepted value is ~55.5.

Medicinal Chemistry and Biopharmaceutics QUESTION #3822

Question 2686

A compounded suspension requires sucralfate $1$ g tablets $\times 8$, sorbitol $70\%$ solution $40$ mL, water to $120$ mL. What percentage (w/v) does sucralfate represent in the final preparation?

$1.0\%$
$6.7\%$✔️
$8.0\%$
$13.4\%$

Correct Answer Logic:

Total sucralfate $= 8 \times 1\ \text{g} = 8\ \text{g}$ in $120$ mL. Percentage $= \dfrac{8}{120} \times 100 = 6.7\%\ \text{w/v}$.

Geography QUESTION #6339

Question 2687

The concept of 'carrying capacity' applied to tourism destinations refers to:

Maximum number of tourists that can be accommodated in hotels
Maximum number of visitors a site can sustain without unacceptable environmental or social impacts✔️
Peak season tourist arrivals
Economic threshold for tourism profitability

Correct Answer Logic:

Tourism carrying capacity is the maximum number of visitors a destination can sustain without causing unacceptable deterioration of physical environment, degradation of visitor experience, or adverse impacts on local community.

Statistics QUESTION #2009

Question 2688

In the ANOVA table for an RCB design with $SS_{error} = 2.6249$ and error $df = 24$, the standard error for the difference between two treatment means $(\bar{y}_{i.} - \bar{y}_{j.})$ is:

$\sqrt{\dfrac{MS_E}{b}}$
$\sqrt{\dfrac{2 \cdot MS_E}{b}}$✔️
$\sqrt{MS_E}$
$\dfrac{MS_E}{b}$

Correct Answer Logic:

The standard error for comparing two treatment means in RCBD is $SE_{diff} = \sqrt{\dfrac{2 MS_E}{b}}$, where $b$ is the number of blocks (replications per treatment). Here $MS_E = 2.6249/24 = 0.1094$, so $SE_{diff} = \sqrt{2(0.1094)/9} \approx 0.1559$.

Information Technology QUESTION #1135

Question 2692

Which mechanism allows a device to inform the CPU that it is ready for data transfer?

Polling
Interrupt✔️
DMA
None of these

Correct Answer Logic:

An interrupt is a signal sent by hardware to the CPU to request immediate attention, allowing the CPU to perform other tasks until the device is ready.

Nursing QUESTION #9308

Question 2693

A patient develops pulmonary edema after rapid IV fluid administration. Which position should the nurse place the patient in?

Supine with legs elevated
High Fowler's position (90 degrees) with legs dependent✔️
Left lateral position
Trendelenburg position

Correct Answer Logic:

In acute pulmonary edema, fluid accumulates in the alveoli, causing severe dyspnea and hypoxia. The High Fowler's position (sitting upright at 90°) with legs dangling off the side of the bed is the priority intervention because:

Gravity pulls fluid away from the lungs (reduces venous return to the heart)
Dependent legs act as venous pooling areas (reduces preload)
Upright position maximizes diaphragmatic descent and lung expansion
Improves ventilation-perfusion matching

Additional nursing interventions in pulmonary edema:

High-flow oxygen or CPAP/BiPAP
IV furosemide (diuretic) — reduces fluid overload
IV morphine — reduces anxiety and vasodilates
Stop IV fluids or drastically reduce rate
Cardiac monitoring

MBBS QUESTION #10324

Question 2694

Acute intermittent porphyria results from a partial deficiency of which heme biosynthetic enzyme, leading to accumulation of porphobilinogen and delta-aminolevulinic acid (ALA) and presenting with abdominal pain, neuropsychiatric symptoms, and dark urine?

Ferrochelatase
Porphobilinogen deaminase (hydroxymethylbilane synthase)✔️
ALA synthase
Uroporphyrinogen decarboxylase

Correct Answer Logic:

Partial deficiency of porphobilinogen deaminase causes acute intermittent porphyria; because this block occurs relatively early in the pathway, ALA and porphobilinogen (rather than photosensitizing porphyrins) accumulate, producing acute neurovisceral attacks without the cutaneous photosensitivity seen in other porphyrias.

Agriculture Economics QUESTION #11871

Question 2695

The profit-maximizing level of input use occurs where:

Marginal Revenue Product equals Marginal Factor Cost, $MRP = MFC$✔️
Average Product is at its maximum
Total Revenue equals Total Cost
Marginal Product equals zero

Correct Answer Logic:

A firm maximizes profit in input space where the added revenue from one more input unit equals its added cost: $MRP = MFC$.

Geology QUESTION #10639

Question 2696

Which of the following processes represents chemical weathering?

Spheroidal weathering
Hydrolysis and hydration✔️
Thermal expansion and contraction
Frost wedging (freeze-thaw)

Correct Answer Logic:

Hydrolysis (reaction of minerals with water, breaking chemical bonds) and hydration (incorporation of water molecules into mineral structure, e.g. anhydrite → gypsum) are classic chemical weathering processes that alter mineral composition. Spheroidal weathering involves corners and edges weathering faster — it is a form of chemical weathering in appearance but driven by differential chemical attack. Thermal expansion and frost wedging are physical/mechanical weathering processes.

Physics QUESTION #4404

Question 2698

A cannon is placed on a smooth surface. When it fires a shell, the cannon moves backward. This recoil occurs due to:

Law of conservation of energy
Backward thrust of the gases
Newton's third law of motion✔️
Newton's first law of motion

Correct Answer Logic:

When the cannon fires a shell forward, by Newton's third law, the shell exerts an equal and opposite reaction force on the cannon backward. This causes the cannon to recoil.

Maths QUESTION #2832

Question 2700

Evaluate: $999^2 - 998 \times 1000$

1✔️
2
3
4

Correct Answer Logic:

Using identity $a^2 - b \times c$: Let $a = 999$, $b=998$, $c=1000$. Note $998 \times 1000 = (999-1)(999+1) = 999^2 - 1$. So $999^2 - (999^2 - 1) = 1$.
