Bio-Technology QUESTION #10625

Question 3

The concept of 'substantial equivalence' in GM food regulation means:

A GM food must be identical in all measurable parameters to its conventional counterpart
A GM food that is as safe and nutritionally equivalent as its conventional counterpart requires no further safety testing✔️
GM and non-GM foods are always equivalent and require no labelling
Substantial quantities of GM material must be present before labelling is required

Correct Answer Logic:

Substantial equivalence (developed by OECD/WHO) is a science-based safety assessment framework: if a GM food is compositionally, nutritionally, and toxicologically similar to its conventional counterpart, it is considered as safe. Assessment involves comparing: gene expression patterns, protein profiles, metabolite compositions, and allergenicity/toxicity indicators. Critics argue it focuses on known components and may miss novel unintended effects. It is the regulatory basis in the USA and Canada but is supplemented by pre-market approval in the EU.

Correct Answer Logic:

Perfectly inelastic demand ($E_d = 0$) means quantity demanded stays fixed no matter how price changes.

Question 8

Which of the following does NOT have the ground-state configuration $1s^2 2s^2 2p^6$?

Ne
Na$^+$
Cl$^-$✔️
None of these

Correct Answer Logic:

Ne has 10 electrons: $1s^2 2s^2 2p^6$ ✓. Na$^+$ has lost one electron from Na (11e$^-$), giving 10e$^-$: $1s^2 2s^2 2p^6$ ✓. Cl$^-$ has gained one electron from Cl (17e$^-$), giving 18e$^-$: $1s^2 2s^2 2p^6 3s^2 3p^6$ — this is the Ar configuration, NOT $1s^2 2s^2 2p^6$. So Cl$^-$ does NOT have this configuration.

Aptitude QUESTION #10997

Question 10

A cylindrical tank of radius $R$ and height $H$ is half-filled with water. A solid metal cone of base radius $\frac{R}{2}$ and height $H$ is completely immersed in the tank with its base facing down. By what fraction of $H$ does the water level rise?

$\frac{1}{6}$
$\frac{1}{8}$
$\frac{1}{12}$✔️
$\frac{1}{24}$

Correct Answer Logic:

Volume of cone: $V = \frac{1}{3}\pi (\frac{R}{2})^2 H = \frac{\pi R^2 H}{12}$. The tank's cross-sectional area is $\pi R^2$. Rise in water level: $\Delta h = \frac{V}{\pi R^2} = \frac{H}{12}$. So the water level rises by $\frac{1}{12}$ of $H$.

Statistics QUESTION #1960

Question 18

If $P(A)$ is the probability of event A, which expression correctly gives the probability of its complement $A^c$?

$1 + P(A)$
$1 - P(A)$✔️
$P(A)$
$P(A) - 1$

Correct Answer Logic:

By the complement rule of probability, $P(A^c) = 1 - P(A)$. Since $P(A) + P(A^c) = 1$, the complement probability is always $1 - P(A)$.
