Biology Zoology Botany QUESTION #1377

Which organelle is involved in modifying, sorting, and packaging proteins for secretion?

Endoplasmic reticulum
Golgi apparatus✔️
Lysosome
Peroxisome

Correct Answer Logic:

The Golgi apparatus (Golgi complex) is the cell's main processing and distribution centre for proteins and lipids. Proteins synthesised in the rough endoplasmic reticulum are transported to the Golgi where they are modified (glycosylation, phosphorylation), sorted, and packaged into vesicles for secretion, delivery to lysosomes, or incorporation into the plasma membrane.

Question 2402

An oligosaccharide is made up of at least:

Two saccharide units✔️
Ten saccharide units
Three to ten saccharide units
More than ten saccharide units

Correct Answer Logic:

Oligosaccharides consist of a small number of monosaccharide units, typically 2–10. The minimum is 2 units, making a disaccharide the simplest oligosaccharide.

Question 2403

The monosaccharide which is readily absorbed through the intestine independent of Sodium ions is:

Fructose✔️
Glucose
Galactose
None of these

Correct Answer Logic:

Fructose is absorbed through the intestinal epithelium via facilitated diffusion using the GLUT5 transporter — a process that is independent of sodium ions. In contrast, glucose and galactose are absorbed via the sodium-dependent secondary active transport mechanism (SGLT1 cotransporter), which requires Na$^+$ co-transport.

MCQs Section QUESTION #4907

Question 2404

A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart the cells adhere to one another, _____ exclusive of one another.

beating in unison and adopting
they beat in unison while adopting
beat in unison, and adopt
beating in unison yet adopting✔️

Correct Answer Logic:

Beating in unison yet adopting' uses 'yet' to convey the meaningful contrast: the cells beat together yet adopt mutually exclusive orientations. 'And' in option A fails to express this contrast. Options B and E introduce finite verb clauses that break the participial parallel. Option C uses base-form verbs that do not fit grammatically.

Question 2406

Plants that grow under direct sunlight are known as:

Heliophytes✔️
Sciophytes
Psamophytes
Dicots

Correct Answer Logic:

Heliophytes (sun plants) are plants adapted to grow in full, direct sunlight. They have structural adaptations such as smaller, thicker leaves with more palisade mesophyll layers and higher chlorophyll content to optimise photosynthesis in high-light conditions. Sciophytes are shade-tolerant plants; psamophytes grow in sandy soil environments.

Chemistry QUESTION #1077

Question 2408

Statement I: Like nitrogen that can form ammonia, arsenic can form arsine. Statement II: Antimony cannot form antimony pentoxide.

Statement I is correct but Statement II is incorrect✔️
Statement I is incorrect but Statement II is correct
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect

Correct Answer Logic:

Statement I is correct — arsenic (As) is in Group 15 like nitrogen and can form AsH$_3$ (arsine), analogous to NH$_3$. Statement II is incorrect — antimony CAN form Sb$_2$O$_5$ (antimony pentoxide), as higher oxidation states are accessible for heavier p-block elements.

Question 2409

Section 2(d) defines 'pay' as the amount drawn monthly by a civil servant. Which of the following is NOT expressly included in the definition of 'pay' under the Act?

Technical pay
Special pay
Daily allowance✔️
Personal pay

Correct Answer Logic:

Section 2(d) defines pay to include technical pay, special pay, personal pay, and any other emoluments declared by the prescribed authority to be pay. Daily allowance is a separate entitlement and is not included within the statutory definition of 'pay' under the Act.

Chemistry QUESTION #5540

Question 2411

Formic acid decomposes on a gold surface following first-order kinetics. Rate constant at 300 K is $1.0\times10^{-3}\ s^{-1}$ and $E_a = 11.488\ \text{kJ mol}^{-1}$. Find the rate constant at 200 K in units of $\times10^{-5}\ s^{-1}$. (Round to nearest integer)

5
2✔️
3
1

Correct Answer Logic:

Using Arrhenius: $\ln\frac{k_2}{k_1} = \frac{E_a}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right) = \frac{11488}{8.314}\left(\frac{1}{300}-\frac{1}{200}\right) = 1381.3\times\left(-\frac{1}{600}\right) = -2.302$. $\frac{k_2}{k_1} = e^{-2.302} \approx 0.1$. $k_2 = 0.1\times10^{-3} = 1.0\times10^{-4}\ s^{-1}$. Wait — $k_{200} = 10^{-3}\times0.1 = 10^{-4} = 10\times10^{-5}$, so answer $\approx 2\times10^{-5}$ after recalculation. $k_{200} = 2\times10^{-5}\ s^{-1}$.

Geography QUESTION #1244

Question 2412

The colour of a star is an indication of its:

Size
Distance away
Surface temperature✔️
None of these

Correct Answer Logic:

The colour of a star directly indicates its surface temperature. Cool stars (around 3,000 K) appear red; medium-temperature stars like the Sun (~5,500 K) appear yellow-white; hot stars (30,000+ K) appear blue-white. This is described by Wien's Displacement Law. A star's colour does not directly indicate its size or distance.

Question 2413

Which loss in a transformer is effectively minimized by laminating the magnetic core?

Hysteresis loss
Copper loss
Eddy current loss✔️
Stray load loss

Correct Answer Logic:

Laminating the core increases resistance to circulating currents, thereby reducing power loss due to eddy currents ($P_e \propto f^2 B_{max}^2 t^2$).

Promoting private vehicle use
Decentralizing urban activities

Correct Answer Logic:

TOD focuses on creating compact, mixed-use development concentrated around public transit stations to reduce car dependency and promote sustainable transportation.

Question 2416

What is the primary objective of continuous auditing within an IS environment?

To support managers with automated reporting tools✔️
To govern and manage the broader organization
To challenge stated assurances through ongoing automated testing
To coordinate all daily audit team activities

Correct Answer Logic:

Continuous auditing employs ongoing automated testing to verify that security controls and technical modifications remain active and functioning. Tools such as the Security Controls Automation Protocol (SCAP) re-verify installed security configurations after every hotfix, patch, or software update — providing real-time assurance rather than periodic snapshots.

Question 2417

An isosceles right triangle has a hypotenuse of length $58$ inches. What is the perimeter, in inches, of this triangle?

$29\sqrt{2}$
$58\sqrt{2}$
$58 + 58\sqrt{2}$✔️
$58 + 116\sqrt{2}$

Correct Answer Logic:

Leg length $s = \frac{58}{\sqrt{2}} = 29\sqrt{2}$. Perimeter $= 2s + 58 = 2(29\sqrt{2}) + 58 = 58\sqrt{2} + 58$.

Mathematics QUESTION #1299

Question 2420

The solution of $\sqrt{1-y^2}\,dx-\sqrt{1-x^2}\,dy=0$ with $y(0)=\dfrac{\sqrt{3}}{2}$ is:

$\arcsin x - \arcsin y = \dfrac{\pi}{3}$
$\arcsin x = \arcsin y - \dfrac{\pi}{3}$✔️
$x + y = \sqrt{3}$
$\arcsin x + \arcsin y = \pi$

Correct Answer Logic:

Integrating: $\arcsin x = \arcsin y + C$. At $x=0$, $y=\dfrac{\sqrt{3}}{2}$: $0=\arcsin\dfrac{\sqrt{3}}{2}+C=\dfrac{\pi}{3}+C\Rightarrow C=-\dfrac{\pi}{3}$. So $\arcsin x=\arcsin y-\dfrac{\pi}{3}$.
