Question 6868

Eight identical spheres of radius $r$ are placed at the vertices of a cube such that each sphere touches its three neighboring spheres. What is the side length of the cube?

$2r$✔️
$2r(1+\sqrt{2})$
$2r(1+\sqrt{3})$
$4r$

Correct Answer Logic:

If spheres at adjacent vertices touch, the distance between centers equals $2r$. For a cube of side $a$, adjacent vertices are distance $a$ apart. Thus $a = 2r$.

Question 6869

Section 14(2) permits a civil servant to seek private employment after retirement. However, if employment is sought within what period after retirement, prior approval of the prescribed authority is mandatory?

One year
Two years✔️
Three years
Six months

Correct Answer Logic:

Section 14(2) provides that where employment is sought by a civil servant while on leave preparatory to retirement or within two years of the date of his retirement, he shall obtain the prior approval of the prescribed authority. The two-year cooling-off period is a significant restriction on post-retirement private employment.

Question 6870

MacConkey agar is a selective and differential medium widely used for the selection of:

Gram-negative strains✔️
Bacilli
Salmonella and Shigella
Staphylococcus

Correct Answer Logic:

MacConkey agar is a selective medium for Gram-negative bacteria. It contains bile salts and crystal violet that inhibit Gram-positive organisms. It is also differential: lactose fermenters (e.g. E. coli) produce acid, turning colonies pink/red due to neutral red indicator; non-fermenters (e.g. Salmonella, Shigella) remain colourless. While Salmonella and Shigella grow on it, the primary selective property is for Gram-negative organisms.

Question 6872

The __________ coefficient is the probability that two alleles in an individual are identical by descent from a common ancestor.

Population
Probability
Inbreeding✔️
Lod score

Correct Answer Logic:

The inbreeding coefficient (F) is the probability that both alleles at a locus in an individual are identical by descent (IBD) — i.e. both copies are inherited from the same ancestral allele through different paths in a pedigree. It ranges from 0 (no inbreeding) to 1 (complete inbreeding). High inbreeding increases homozygosity and the expression of deleterious recessive alleles, reducing fitness (inbreeding depression).

Question 6877

In the context of Town Planning, the concept of a 'Neighbourhood Unit' as proposed by Clarence Perry (1920s) specifies that the unit should be sized to support one elementary school, with the recommended population being approximately:

500–1,000 persons
3,000–5,000 persons✔️
10,000–15,000 persons
20,000–25,000 persons

Correct Answer Logic:

Clarence Perry's Neighbourhood Unit (1929) was sized to support one elementary school, with a recommended population of approximately 3,000–5,000 persons within a ¼-mile (400 m) walking radius from the centre. The unit is bounded by arterial roads (not penetrated by through traffic), with parks/open spaces, local shops, and community facilities at its centre. This concept influenced modern residential planning and the Garden City movement.

Physics QUESTION #997

Question 6878

A tube of length $L$ has radius 2 cm at point (1) and 1 cm at point (2). If velocity of water entering at point (1) is $2\ \text{m/s}$, the velocity of water leaving at point (2) will be:

4 m/s
2 m/s
6 m/s
8 m/s✔️

Correct Answer Logic:

By continuity equation: $A_1 v_1 = A_2 v_2$. $\pi(2)^2 \times 2 = \pi(1)^2 \times v_2 \Rightarrow v_2 = \frac{4\times2}{1} = 8\ \text{m/s}$.

Question 6880

Bactofugation removes bacteria from milk using:

Microfiltration membranes
High-speed centrifugation exploiting density difference between bacteria $(\rho \approx 1.1\;\text{g/mL})$ and milk $(\rho \approx 1.032\;\text{g/mL})$✔️
UV irradiation
Chemical bacteriostats

Correct Answer Logic:

Bactofugation uses centrifugal separators rotating at $\approx 20{,}000$ rpm. Bacteria $(\rho \approx 1.1\;\text{g/mL})$ are denser than milk $(\rho \approx 1.032\;\text{g/mL})$ and are sedimented as a concentrate, reducing spore count by up to $99\%$.
