English QUESTION #11594

The two brothers are _____ in appearance, but not in personality.

like
same
alike✔️
None of these

Correct Answer Logic:

Alike is correct. It is a predicate adjective meaning “similar” and is used after a verb (e.g., “They are alike”). Like is used as a preposition before a noun (e.g., “He looks like his father”). Same requires the definite article “the” (e.g., “They look the same”) and cannot stand alone without it.

Correct Answer: C — alike.

Question 2

Hemophilia A results from deficiency of which clotting factor, producing an isolated prolongation of the activated partial thromboplastin time (aPTT) with a normal prothrombin time (PT)?

Factor VII
Factor VIII✔️
Factor IX
Factor XI

Correct Answer Logic:

Factor VIII deficiency (Hemophilia A) selectively prolongs the aPTT (intrinsic pathway) while the PT (extrinsic pathway, factor VII-dependent) remains normal. Factor IX deficiency causes the clinically similar Hemophilia B, with an identical aPTT/PT pattern, distinguished only by specific factor assays.

Bio-Technology QUESTION #10609

Question 5

Inclusion bodies formed during recombinant protein overexpression in E. coli are:

Membrane-bound vesicles containing properly folded protein
Dense intracellular aggregates of misfolded or partially unfolded recombinant protein✔️
Plasmid DNA aggregates that form when copy number is too high
Peroxisomes containing oxidised protein

Correct Answer Logic:

Inclusion bodies form in E. coli when recombinant protein accumulates faster than the cellular chaperone machinery can fold it. The misfolded protein aggregates into dense, insoluble intracellular particles. Recovery requires: cell disruption → centrifugal isolation of inclusion bodies → solubilisation with chaotropic agents (6–8 M urea or guanidinium chloride) → controlled refolding by dilution or dialysis into native buffer. Despite the extra steps, inclusion bodies offer high-purity protein and protection from proteolysis.

Physics QUESTION #7034

Question 7

A student records the length of a rod as $3.50 \text{ cm}$. Identify the instrument used for this measurement based on its precision.

A screw gauge with a pitch of $1 \text{ mm}$ and $100$ circular scale divisions
A screw gauge with a pitch of $1 \text{ mm}$ and $50$ circular scale divisions
A standard metre scale
A vernier calliper where $10$ divisions of the vernier scale coincide with $9$ main scale divisions (main scale has $10 \text{ divisions per cm}$)✔️

Correct Answer Logic:

The recorded value $3.50 \text{ cm}$ has a precision of $0.01 \text{ cm}$. We must find an instrument with a least count (LC) of $0.01 \text{ cm}$.

Option A: $LC = \frac{1 \text{ mm}}{100} = 0.01 \text{ mm} = 0.001 \text{ cm}$
Option B: $LC = \frac{1 \text{ mm}}{50} = 0.02 \text{ mm} = 0.002 \text{ cm}$
Option C: $LC = 0.1 \text{ cm}$
Option D: $1 \text{ MSD} = \frac{1 \text{ cm}}{10} = 0.1 \text{ cm}$. Since $10 \text{ VSD} = 9 \text{ MSD}$, $1 \text{ VSD} = 0.9 \text{ MSD}$. $LC = 1 \text{ MSD} - 1 \text{ VSD} = 0.1 \text{ MSD} = 0.01 \text{ cm}$.

Thus, Option D matches the required precision.

Question 9

Which one of the following is a vascular cryptogam?

Cedrus
Equisetum✔️
Ginkgo
Marchantia

Correct Answer Logic:

Equisetum (horsetail) is a vascular cryptogam — it has a well-developed vascular system but reproduces by spores (not seeds). Pteridophytes are vascular cryptogams. Cedrus and Ginkgo are gymnosperms (vascular but phanerogams/seed plants). Marchantia is a liverwort — non-vascular.

Question 12

A merchant sends a signed purchase order to a manufacturer for 1,000 widgets at $\text{\$5}$ each. The manufacturer sends back a signed acknowledgment form that says, 'We accept, but all disputes must be settled by arbitration in New York.' The original order was silent on arbitration. Under UCC 2-207 (Battle of the Forms), is the arbitration clause part of the contract?

No, because it is a 'material alteration.'✔️
Yes, because both parties are merchants and the merchant did not object.
No, because the manufacturer's form was a counter-offer.
Yes, because the manufacturer's signature makes it a 'firm offer.'

Correct Answer Logic:

Under UCC 2-207, between merchants, additional terms become part of the contract unless they materially alter it. Courts generally hold that an arbitration clause is a material alteration.

Question 17

Allopurinol, commonly used in the long-term management of gout, lowers uric acid production by inhibiting which enzyme?

Hypoxanthine-guanine phosphoribosyltransferase (HGPRT)
Xanthine oxidase✔️
Adenosine deaminase
Phosphoribosyl pyrophosphate (PRPP) synthetase

Correct Answer Logic:

Xanthine oxidase catalyzes the final steps of purine catabolism (hypoxanthine to xanthine to uric acid); allopurinol (and its active metabolite oxypurinol) inhibits this enzyme, reducing uric acid production and shifting excretion toward the more soluble precursors hypoxanthine and xanthine.

Question 19

The bandwidth $\omega_b$ of a closed-loop control system is defined as the frequency at which the closed-loop magnitude $M(\omega)$ drops to:

$M(\omega_b) = M(0)/2$
$M(\omega_b) = M(0)/\sqrt{2}$ (i.e., $-3$ dB below $M(0)$)✔️
$M(\omega_b) = 0$
$M(\omega_b) = M(0) \cdot \sqrt{2}$

Correct Answer Logic:

Bandwidth: $M(\omega_b)=M(0)/\sqrt{2}$, i.e., the response is $-3$ dB below its low-frequency value. In dB: $20\log M(\omega_b)=20\log M(0)-3$ dB. Larger bandwidth means faster system response.
