Biology QUESTION #4333

Question 5062

Reversible inhibitors differ from irreversible inhibitors because they:

Bind permanently and cannot be removed
Bind temporarily and can be removed✔️
Permanently inactivate the enzyme
Change enzyme structure permanently

Correct Answer Logic:

Reversible inhibitors bind through weak, non-covalent interactions and can be removed, restoring enzyme activity. Irreversible inhibitors form permanent covalent bonds with the enzyme.

$1,000 + (1,000 \times 0.10 \times 5)$

Correct Answer Logic:

Lesson 04 specifies that for continuous compounding, $FV = PV \times e^{i \times n}$.

Question 5066

Choose the correct ARTICLE: '___ sun rises in the east.'

A
An
The✔️

Paper-II (Pharmacognosy and Pharmaceutics-I) QUESTION #2987

Question 5067

How much $95\%$ alcohol is needed to prepare $500\text{ ml}$ of $70\%$ alcohol?

$368.4\text{ ml}$✔️
$350\text{ ml}$
$420.5\text{ ml}$
$300.0\text{ ml}$

Correct Answer Logic:

Using $C_1V_1 = C_2V_2$: $95 \times V_1 = 70 \times 500 \implies V_1 = 35000 / 95 \approx 368.4\text{ ml}$.

Mechanical Engineering QUESTION #2460

Question 5069

For a simple gear train with gears 1, 2, and 3 in series (gear 2 is an idler), the overall velocity ratio $i_{13}$ between gear 1 (input) and gear 3 (output) is:

$i_{13} = -\frac{N_3}{N_1}$ (idler gear 2 only affects sign, not magnitude)✔️
$i_{13} = -\frac{N_2 N_3}{N_1^2}$
$i_{13} = \frac{N_1}{N_3}$
$i_{13} = \frac{N_1 N_2}{N_2 N_3}$

Correct Answer Logic:

For a simple gear train: $i_{13}=\left(-\frac{N_2}{N_1}\right)\left(-\frac{N_3}{N_2}\right)=-\frac{N_3}{N_1}$. The idler gear 2 cancels out in magnitude but reverses the direction sign once.

Question 5071

An office computer stores a simple text file containing exactly 5 characters (5 bytes). How many bits of storage does this file use?

5 bits
10 bits
20 bits
40 bits✔️

Correct Answer Logic:

Since 1 byte = 8 bits: $5 \times 8 = 40$ bits. Each character in a simple text file typically requires 1 byte (8 bits) of storage. This is a fundamental calculation for understanding file sizes and storage requirements.

Question 5073

Solve: $\frac{x}{4} = 5$

$x = 1.25$
$x = 9$
$x = 20$✔️
$x = \frac{5}{4}$

Correct Answer Logic:

Multiply both sides by $4$: $x = 5 \times 4 = 20$

Mathematics QUESTION #979

Question 5074

The sum of all values of $\theta\in[0,2\pi]$ satisfying $2\sin^2\theta=\cos 2\theta$ and $2\cos^2\theta=3\sin\theta$ is:

$4\pi$
$\dfrac{5\pi}{6}$
$\pi$✔️
$\dfrac{\pi}{2}$

Correct Answer Logic:

From $2\sin^2\theta=\cos2\theta=1-2\sin^2\theta \Rightarrow 4\sin^2\theta=1 \Rightarrow \sin\theta=\pm\frac{1}{2}$. From $2\cos^2\theta=3\sin\theta \Rightarrow 2(1-\sin^2\theta)=3\sin\theta \Rightarrow 2\sin^2\theta+3\sin\theta-2=0 \Rightarrow \sin\theta=\frac{1}{2}$ (taking positive root). So $\theta=\frac{\pi}{6}$ or $\frac{5\pi}{6}$. Sum$=\frac{\pi}{6}+\frac{5\pi}{6}=\pi$.

Electrical Engineering QUESTION #2167

Question 5076

The z-transform of $x[n] = a^n u[n]$ is $X(z) = \frac{z}{z-a}$ with ROC $|z|>|a|$. For $a = 0.8$, the final value $\lim_{n \to \infty} x[n]$ is:

$0$✔️
$1$
$0.8$
Diverges to infinity

Correct Answer Logic:

Since $|a| = 0.8 < 1$, $\lim_{n\to\infty}(0.8)^n = 0$. Confirmed by the Final Value Theorem: $\lim_{z\to1}(z-1)X(z) = \lim_{z\to1}\frac{z(z-1)}{z-0.8} = 0$.

Question 5078

The total axial deformation $\delta$ of a bar of length $l$, cross-sectional area $A$, modulus of elasticity $E$, under axial force $F$ is:

$\delta = \frac{AE}{Fl}$
$\delta = \frac{Fl}{AE}$✔️
$\delta = \frac{FA}{El}$
$\delta = FAEl$

Correct Answer Logic:

From Hooke's Law: $\sigma = E\varepsilon$, where $\sigma = F/A$ and $\varepsilon = \delta/l$. Solving: $\delta = Fl/(AE)$.

Biology Zoology Botany QUESTION #1338

Question 5079

Which co-enzyme is NOT involved in oxidative decarboxylation of pyruvic acid?

CoA-SH
$\text{Mg}^{2+}$
Biotin✔️
None of these

Correct Answer Logic:

The oxidative decarboxylation of pyruvate to acetyl-CoA (by pyruvate dehydrogenase complex) requires five coenzymes: CoA-SH, NAD$^+$, FAD, TPP (thiamine pyrophosphate), and lipoic acid. $\text{Mg}^{2+}$ serves as a cofactor for the enzyme. Biotin is NOT involved — it is a cofactor for carboxylation reactions (e.g., pyruvate carboxylase), not decarboxylation.

Ability / HR / Governance / Special Education QUESTION #5648

Question 5080

The Regular Supplementary Grant differs fundamentally from the Technical Supplementary Grant in one critical way. Which statement CORRECTLY captures this distinction?

Regular Supplementary Grant requires Parliamentary presentation while Technical Supplementary Grant does not
Regular Supplementary Grant involves an upward change (additionality) in the sanctioned budget grant while Technical Supplementary Grant merely transfers funds between Grants/Demands without implying additionality✔️
Technical Supplementary Grant can only be used for Development Expenditure while Regular Supplementary Grant covers Current Expenditure
Regular Supplementary Grant is sanctioned by the Finance Division while Technical Supplementary Grant is sanctioned by the PAO

Correct Answer Logic:

The Technical Supplementary Grant does not imply any additionality to the sanctioned budget grant (it is a transfer from one Grant/Demand to another due to savings). The Regular Supplementary Grant involves an upward change in the sanctioned budget grant (actual additionality). Both must be presented to Parliament for ex-post authorization.
