Bio-Technology QUESTION #10573

In reporter gene technology, a translational fusion (as opposed to a transcriptional fusion) produces:

A separate reporter protein translated from its own RBS
A chimeric protein in which the reporter is fused in-frame to the target protein✔️
An antisense RNA that inhibits target gene expression
A bicistronic mRNA with two independent translation units

Correct Answer Logic:

In a translational fusion, the reporter gene (e.g. lacZ, GFP) is fused in the same reading frame as the target gene, producing a single chimeric fusion protein. This allows detection of both transcriptional and post-transcriptional regulation and can reveal protein localisation within cells. In contrast, a transcriptional fusion places the reporter downstream with its own RBS, detecting only promoter activity.

Mathematics QUESTION #11212

Question 3

Which of the following is NOT an integral domain?

$\mathbb{Z}$
$\mathbb{Z}_7$
$\mathbb{Q}$
Set $M_2$ of $2\times 2$ matrices with integer entries✔️

Correct Answer Logic:

An integral domain is a commutative ring with unity and no zero divisors. The set $M_2(\mathbb{Z})$ of $2\times 2$ integer matrices is not commutative and has zero divisors (e.g. $\begin{pmatrix}1&0\\0&0\end{pmatrix}\begin{pmatrix}0&0\\0&1\end{pmatrix}=0$). Hence it is NOT an integral domain. $\mathbb{Z}$, $\mathbb{Z}_7$ (prime modulus), and $\mathbb{Q}$ are all integral domains.

Reading and Writing (Module-1) QUESTION #5420

Question 7

While researching a topic, a student has taken the following notes: • Chemical leavening agents cause carbon dioxide to be released within a liquid batter, making the batter rise as it bakes. • Baking soda and baking powder are chemical leavening agents. • Baking soda is pure sodium bicarbonate. • To produce carbon dioxide, baking soda needs to be mixed with liquid and an acidic ingredient such as honey. • Baking powder is a mixture of sodium bicarbonate and an acid. • To produce carbon dioxide, baking powder needs to be mixed with liquid but not with an acidic ingredient. The student wants to emphasize a difference between baking soda and baking powder. Which choice most effectively uses relevant information from the notes to accomplish this goal?

To make batters rise, bakers use chemical leavening agents such as baking soda and baking powder.
Baking soda and baking powder are chemical leavening agents that, when mixed with other ingredients, cause carbon dioxide to be released within a batter.
Baking soda is pure sodium bicarbonate, and honey is a type of acidic ingredient.
To produce carbon dioxide within a liquid batter, baking soda needs to be mixed with an acidic ingredient, whereas baking powder does not.✔️

Correct Answer Logic:

This choice directly contrasts the key difference: baking soda requires an acidic ingredient while baking powder doesn't.

Boilers Mechanical Engineering QUESTION #2405

Question 9

The Mach number $Ma$ for a compressible flow with velocity $V$ and speed of sound $c=\sqrt{E/\rho}$ is:

$Ma = V/c = V/\sqrt{E/\rho}$✔️
$Ma = c/V$
$Ma = V^2/(E/\rho)$
$Ma = E/(V\rho)$

Correct Answer Logic:

Mach number: $Ma=V/c$ where $c=\sqrt{E/\rho}=\sqrt{\gamma RT}$ is the speed of sound. Flow regimes: subsonic ($Ma<1$), sonic ($Ma=1$), supersonic ($Ma>1$).

Civil Engineering QUESTION #2134

Question 11

In irrigation engineering, the duty of water ($\Delta$) and delta ($D$) are related to base period ($B$) in days by the equation:

D = B × $\Delta$
D = $\dfrac{8.64 \times B}{\Delta}$✔️
D = $\dfrac{\Delta}{8.64 \times B}$
D = $\dfrac{B}{8.64 \times \Delta}$

Correct Answer Logic:

Duty ($\Delta$) = area (hectares) irrigated by 1 cumec (1 m³/s) of water flowing continuously for base period $B$ (days). Delta ($D$) = total depth of water (meters) required by the crop in base period. Relationship: $D = \dfrac{8.64 \times B}{\Delta}$, derived from: 1 cumec flowing for $B$ days delivers $8.64B \times 10^4$ liters over $\Delta$ hectares. This fundamental relationship governs canal design and water distribution in irrigation systems.

Geography QUESTION #1233

Question 12

The ______ is the chemical breakdown of a compound due to reaction with water.

Hydration
Oxidation
Hydrolysis✔️
None of these

Correct Answer Logic:

Hydrolysis is a chemical weathering process in which water reacts with minerals in rocks to form new compounds. For example, feldspar reacts with water to form clay minerals. Hydration is the absorption of water into the mineral structure, and oxidation involves reaction with oxygen. Hydrolysis is specifically the chemical breakdown via water reaction.

Maths QUESTION #7948

Question 14

A 100-metre long train passes a bridge at 72 km/hr in 25 seconds. What is the length of the bridge?

400 m✔️
170 m
600 m
None

Correct Answer Logic:

Speed $= 72 \text{ km/hr} = 72 \times \dfrac{1000}{3600} = 20 \text{ m/s}$
Total distance covered in 25 s $= 20 \times 25 = 500$ m
Length of bridge $= 500 - 100 = 400$ m

Accounting & Finance QUESTION #6111

Question 15

Draft loss for year: $320. Adjustments needed: (1) Irrecoverable debts of $930 recovered; (2) Existing allowance $520, required allowance = 5% of trade receivables $9,600. What is the revised profit or loss?

Loss of $1,210
Loss of $1,730
Profit of $130
Profit of $650✔️

Correct Answer Logic:

Option D (Profit of $650) is correct.

Recovery of debt: +$930

Required allowance = 5% × $9,600 = $480; Reduction = $520 − $480 = +$40

Revised = −$320 + $930 + $40 = +$650 profit

Nursing QUESTION #9170

Question 17

A Head Nurse is evaluating nursing staff performance. According to Donabedian's Model of quality care, which component evaluates the process of care?

Availability of adequate nursing staff (structure)
Whether nursing procedures were followed correctly (process)✔️
Patient outcomes after discharge (outcome)
Number of beds in the facility (structure)

Correct Answer Logic:

Donabedian's Model of Quality (1966) has three components:

Component	Definition	Examples
Structure	Resources and organizational features	Staff ratios, equipment, facility design
Process	Activities that constitute health care delivery	Adherence to protocols, documentation, patient assessment techniques
Outcome	Changes in patient health status	Mortality rates, patient satisfaction, complication rates

Whether nursing procedures were followed correctly is a process indicator.
