The liver possesses the enzymes to synthesize ketone bodies but lacks thiophorase, required to reactivate acetoacetate back to acetoacetyl-CoA for further metabolism; this ensures ketone bodies are exported for use as fuel by extrahepatic tissues (brain, heart, skeletal muscle) rather than being consumed by the liver that produces them.

Maths QUESTION #4540

Question 6046

What is $\frac{3}{4} + \frac{1}{4}$?

$\frac{4}{8}$
$1$
$\frac{4}{4}$
Both B and C✔️

Correct Answer Logic:

$\frac{3}{4} + \frac{1}{4} = \frac{3+1}{4} = \frac{4}{4} = 1$. Both options B and C are correct.

Civil Engineering QUESTION #6609

Question 6047

Which of the following parameters is used to categorize a steel section as 'compact' for flexure?

The ratio of flange width to thickness ($b/t$)✔️
The total depth of the beam ($d$)
The span-to-depth ratio ($L/d$)
The poisson's ratio ($\nu$)

Correct Answer Logic:

Compactness is a measure of a section's ability to develop its full plastic moment without local buckling. It is determined by checking the width-to-thickness ratios ($b/t$ for flanges, $h/t_w$ for webs) against limits $\lambda_p$.

Dairy Food Science and Technology QUESTION #5931

Question 6048

Somatic cell count (SCC) in milk is used as an indicator of:

Antibiotic contamination
Fat content variation
Udder health — elevated SCC ($>200{,}000\text{–}400{,}000\;\text{cells/mL}$) indicates mastitis✔️
Bacterial contamination from the environment

Correct Answer Logic:

SCC measures white blood cells and mammary epithelial cells shed into milk. Normal SCC $< 200{,}000\;\text{cells/mL}$; SCC $> 400{,}000\;\text{cells/mL}$ (EU limit) indicates subclinical mastitis, which reduces milk quality (lower casein, higher plasmin, reduced shelf life).

Chemistry QUESTION #7502

Question 6051

Match the compounds in Item I with their correct detection reagents in Item II:

Item I (Compound)	Item II (Reagent)
(A) Lysine	(P) 1-naphthol
(B) Furfural	(Q) Ninhydrin
(C) Benzyl alcohol	(R) KMnO$_4$
(D) Styrene	(S) Ceric ammonium nitrate

(A)→(Q); (B)→(P); (C)→(S); (D)→(R)✔️
(A)→(Q); (B)→(P); (C)→(R); (D)→(S)
(A)→(R); (B)→(P); (C)→(Q); (D)→(S)
(A)→(Q); (B)→(R); (C)→(S); (D)→(P)

Correct Answer Logic:

Matching logic:

Lysine is an amino acid — detected by ninhydrin (Q), which gives a purple colour with primary amines/amino acids.
Furfural is an aldehyde from furan — detected by 1-naphthol (P) via the Tollens-type or colour reaction specific to furfural.
Benzyl alcohol (PhCH$_2$OH) is a primary alcohol — detected by ceric ammonium nitrate (S), which gives a red colour with alcohols.
Styrene (Ph–CH=CH$_2$) has a C=C bond — oxidized by KMnO$_4$ (R), which gets decolourized.

Correct match: (A)→(Q), (B)→(P), (C)→(S), (D)→(R)

Question 6052

MS Office provides built-in user assistance through features such as:

Help Menu
'What is this?' tool
Office Assistant
All of the above✔️

Correct Answer Logic:

MS Office provides help through all of the above: (A) Help menu (F1 or Help tab), (B) 'What's This?' (Shift+F1 in older versions — context-sensitive help), and (C) Office Assistant (Clippy in Office 97–2003). In modern Office, help is via the Tell Me search box (lightning bolt icon).

Law QUESTION #9679

Question 6053

Under Article 37, a confession made by an accused person is irrelevant in criminal proceedings if it was caused by inducement, threat or promise — from whom must such inducement come?

Any person
A co-accused

Paper-I (Anatomy/Physiology and Biochemistry/Microbiology) QUESTION #3528

Question 6054

Why is 'Cold Compression' used for extracting Lemon Oil rather than Steam Distillation?

Heat would destroy the delicate aroma and degrade the chemical constituents✔️
Cold compression is cheaper
Lemon oil is a solid
Lemon oil doesn't evaporate

Correct Answer Logic:

Many citrus oils are obtained by expression (pressing) to preserve their fresh quality.

Constitutional Law QUESTION #5831

Question 6055

A state law prohibits anyone from receiving an out-of-state shipment of wine unless they are a licensed wholesaler. In-state wineries, however, are permitted to ship directly to consumers. Is this law constitutional?

Yes, because the 21st Amendment gives states absolute power over the distribution of alcohol.
No, because it violates the Dormant Commerce Clause by discriminating against out-of-state wineries.✔️
Yes, because the state has a rational basis to regulate alcohol for health and safety.
No, because it violates the Privileges and Immunities Clause of the 14th Amendment.

Correct Answer Logic:

While the 21st Amendment gives states power to regulate alcohol, it does not override the Commerce Clause. Under Granholm v. Heald, states cannot allow in-state wineries to ship to consumers while prohibiting out-of-state wineries from doing the same.

Agronomy QUESTION #2069

Question 6056

The competition between component crops in intercropping systems is best quantified using the Competitive Ratio (CR), where $CR_A > 1$ indicates that:

Crop A is producing lower yield than crop B in the intercrop
Crop A is more competitive than crop B — it acquires a greater share of the growth resources (light, water, nutrients) relative to its share in sole cropping, usually at the expense of crop B✔️
The intercropping system has a LER greater than 1
Both crops are equally competitive and the system is in equilibrium

Correct Answer Logic:

Competitive Ratio $CR_A = \dfrac{LER_A}{LER_B} \times \dfrac{Z_B}{Z_A}$, where $Z$ is the proportion of each crop in the mixture. $CR_A > 1$ means Crop A acquires more than its proportional share of resources. Managing CR guides choice of species combinations, row arrangements, and relative densities to reduce dominance of one component and improve overall system productivity.

Geography QUESTION #6334

Question 6057

The concept of 'comparative advantage' in international trade, developed by David Ricardo, implies countries should:

Specialize in producing goods they produce most efficiently in absolute terms
Specialize in goods where they have the lowest opportunity cost relative to other countries✔️
Produce everything domestically to avoid trade dependence
Export only technologically advanced products

Correct Answer Logic:

Comparative advantage states countries should specialize in producing goods where they have the lowest opportunity cost (what they sacrifice least to produce). Even if Country A produces everything more efficiently than Country B, both benefit from specialization and trade based on relative efficiency.

Biology Zoology Botany QUESTION #10781

Question 6058

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.
