During metaphase (the middle phase of mitosis), chromosomes become maximally condensed and are aligned along the cell's equatorial plane (metaphase plate) by spindle fibres attached to the centromeres (kinetochores). This alignment ensures accurate segregation of sister chromatids to the two daughter cells in the subsequent anaphase.

Mathematics QUESTION #1283

Question 564

The function $f(x)=e^x$ satisfies the Mean Value Theorem on $[0,1]$. The value of $c\in(0,1)$ guaranteed by MVT satisfies:

e^c = e-1✔️
$e^c=\dfrac{e+1}{2}$
e^c=\dfrac{1}{e}
e^c=1

Correct Answer Logic:

By MVT: $f'(c)=\dfrac{f(1)-f(0)}{1-0}=\dfrac{e-1}{1}=e-1$. Since $f'(x)=e^x$, we get $e^c=e-1$. Since \(1

Mathematics QUESTION #6955

Question 566

Let $[x]$ denote the greatest integer $\leq x$. Find: $\displaystyle\lim_{x\to0}\dfrac{\tan(\pi\sin^2 x)+(|x|-\sin(x[x]))^2}{x^2}$

Does not exist
Equals $\pi$✔️
Equals $\pi+1$
Equals 0

Correct Answer Logic:

Split into right and left limits.

Right limit ($x\to0^+$): $[x]=0$, so $\sin(x[x])=0$, $|x|=x$.

$\dfrac{\tan(\pi\sin^2x)+x^2}{x^2}$. Using $\tan(\pi\sin^2x)\approx\pi\sin^2x\approx\pi x^2$:

$=\pi+1$

Left limit ($x\to0^-$): $[x]=-1$, $\sin(x[x])=\sin(-x)=-\sin x$, $|x|=-x$.

$=\dfrac{\tan(\pi\sin^2x)+(-x-(-\sin x))^2}{x^2}=\dfrac{\pi x^2+(\sin x-x)^2}{x^2}\to\pi+0=\pi$

Left $\neq$ Right, so the limit does not exist.

Planning QUESTION #4929

Question 567

What does FAR (Floor Area Ratio) measure?

Building height to width ratio
Total floor area to plot area ratio✔️
Number of floors in a building
Facade area to plot ratio

Correct Answer Logic:

FAR is calculated as $\frac{\text{Total Floor Area}}{\text{Plot Area}}$ and indicates development intensity, controlling building bulk and density on a site.

Social Studies QUESTION #10037

Question 568

Which index is most directly designed to measure gender inequality?

Gender Development Index (GDI)✔️
Gender Empowerment Measure (GEM)
Human Development Index (HDI)
All of these

Correct Answer Logic:

The GDI adjusts the HDI to reflect gender-based disparities, making it a direct measure of gender inequality, unlike the HDI itself.

Quantitative Reasoning QUESTION #8037

Question 571

EXPAND : VOLUME :: (Find the pair that best matches the relationship between the given words)

ascend : flight
proliferate : number✔️
bend : flexibility
cool : temperature

Correct Answer Logic:

To EXPAND is to increase VOLUME — the verb causes an increase in that measurable quantity. To proliferate is to increase in number — the verb similarly causes an increase in that quantity. Both pairs = [verb meaning to increase] : [the measurable quantity that increases]. 'Cool:temperature' is the opposite (cooling decreases temperature).

Chemistry QUESTION #7113

Question 572

Identify which of the following salts will produce the most basic solution when dissolved in water at equal concentrations.

$FeCl_{3}$
$Pb(CH_{3}COO)_{2}$
$Al(CN)_{3}$
$CH_{3}COOK$✔️

Correct Answer Logic:

A basic solution is formed by the hydrolysis of a salt derived from a strong base and a weak acid. $CH_3COOK$ is formed from $KOH$ (strong base) and $CH_3COOH$ (weak acid). Upon hydrolysis, it produces $OH^-$ ions, making the solution basic. The other salts involve weak bases or strong acids, resulting in acidic or less basic solutions.

Administration QUESTION #9545

Question 573

The Systems School borrowed the concept of 'system' from biological sciences. A government ministry receives a report that its policy outputs are producing unintended social consequences. According to Systems Theory, what mechanism allows the organization to detect and correct this?

Synergy — the combined output of the ministry exceeds what individual departments produce alone
Feedback — information about outputs is returned to the organization to adjust inputs and processes✔️
Subsystem interdependence — related departments automatically realign when external conditions change
Open system boundary — the ministry absorbs environmental change without requiring structural adjustment

Correct Answer Logic:

Feedback is the core corrective mechanism in Systems Theory — information about actual outputs (outcomes) is returned to the system to allow adjustment of inputs and transformation processes. Without feedback loops, organizations cannot detect or respond to unintended consequences.

Math Physics Chemistry Biology QUESTION #11285

Question 575

Which of the following is a density-dependent limiting factor for population growth?

Natural disasters
Climate change
Disease outbreak✔️
Seasonal temperature fluctuations

Correct Answer Logic:

Density-dependent factors affect population growth based on population density. Disease outbreaks spread more easily in dense populations. Natural disasters, climate change, and temperature fluctuations are density-independent factors that affect populations regardless of size.

Accounting & Finance QUESTION #6123

Question 576

Factory data: Budgeted production 10,000 units; Budgeted overheads $50,000; Actual overheads $60,000; Under-absorption $5,000. What was the actual production?

9,000 units✔️
9,167 units
11,000 units
13,000 units

Correct Answer Logic:

Option A (9,000 units) is correct.

OAR = $50,000 ÷ 10,000 = $5 per unit

Under-absorption = Actual overheads − Absorbed overheads

$5,000 = $60,000 − (Actual units × $5)

Actual units = $55,000 ÷ $5 = 9,000 units

Education QUESTION #10900

Question 577

Project method
Textbook method
Lecture method✔️
Inquiry method

Correct Answer Logic:

The lecture method is the most universally popular teaching method across all educational levels — from primary schools to universities. Despite its limitations (passive students, one-way communication, ignores individual differences), it remains dominant because it is economical, can cover large amounts of content quickly, requires minimal materials, can reach large groups simultaneously, and teachers are most trained in it. Its universality and practicality make it the most widely used method globally.

Education QUESTION #6730

Question 579

A student demonstrates knowledge when explaining concepts to peers but struggles on written tests. This MOST likely indicates:

Lack of true understanding
Need for alternative assessment methods recognizing diverse intelligences✔️
Academic dishonesty
Poor test-taking skills only

Correct Answer Logic:

Multiple intelligences suggest people demonstrate understanding differently. Strong verbal-interpersonal intelligence may not translate to linguistic-written performance. Authentic assessment should include varied methods (oral explanation, demonstration, written work) to capture true understanding.
