Accounting & Finance QUESTION #1229

A zero-coupon bond sells for $ 250. At maturity in 16 years, it will be redeemed for $ 1,000. What approximate annual rate of growth does this represent?

8 percent✔️
9 percent
12 percent
25 percent

Correct Answer Logic:

Using the future value formula: $FV = PV \times (1+r)^n$. So $1000 = 250\times(1+r)^{16}$. $(1+r)^{16} = 4$. $1+r = 4^{1/16} = 4^{0.0625}$. $\ln(1+r) = \frac{\ln 4}{16} = \frac{1.386}{16} = 0.0866$. $1+r = e^{0.0866} \approx 1.0905$. So $r \approx 9\%$. Wait: $4^{1/16}$: $\log(4)/16 = 0.602/16=0.0376$, antilog $=1.089$, so $r\approx 9\%$ = option (B). Re-examining: $4^{0.0625}=1.0905\Rightarrow r\approx9\%$. Answer: option (B) = 9 percent.

Question 3

In the design of a rectangular RC beam, the depth of the equivalent rectangular stress block ($a$) is related to the neutral axis depth ($c$) by the factor $\beta_1$. For concrete with $f'_c = 5000$ psi, what is the value of $\beta_1$?

0.85
0.8✔️
0.75
0.7

Correct Answer Logic:

For $f'_c$ between 2500 and 4000 psi, $\beta_1$ is 0.85. For $f'_c > 4000$ psi, $\beta_1$ is reduced by 0.05 for every 1000 psi increment. $0.85 - 0.05 \times ((5000-4000)/1000) = 0.80$.

Question 6

During 'Depolarization' of an action potential, which ion rushes into the cell?

$K^+$
$Na^+$✔️
$Ca^{2+}$
$Cl^-$

Correct Answer Logic:

Opening of voltage-gated sodium channels allows $Na^+$ to enter, making the membrane potential more positive.

Question 7

Which of the following is true?

$\text{Na}^+$ is smaller than $\text{Na}$✔️
$\text{Cl}^-$ is less than $\text{Cl}$
$\text{Na}^+$ is greater than $\text{Na}$
None

Correct Answer Logic:

When $\text{Na}$ loses an electron to form $\text{Na}^+$, the electron cloud shrinks due to increased nuclear charge per electron, making $\text{Na}^+$ smaller than $\text{Na}$.

Bio-Technology QUESTION #10617

Question 12

Monoclonal antibodies (mAbs) are produced by hybridoma technology, which involves:

Immunising mice and isolating serum containing a mixture of all antibodies produced
Fusing antigen-specific B lymphocytes with immortal myeloma cells to create stable, antibody-secreting hybridomas✔️
Cloning antibody genes into phage display vectors for in vitro selection
Chemical conjugation of multiple antibody fragments to increase avidity

Correct Answer Logic:

Hybridoma technology (Köhler and Milstein, 1975 — Nobel Prize 1984) involves: (1) immunising a mouse with the target antigen, (2) isolating antigen-specific splenic B cells, (3) fusing B cells with myeloma cells (immortal, non-secreting) using PEG, (4) selecting hybridomas in HAT medium (unfused myeloma cells die; unfused B cells die naturally), (5) cloning and screening for the desired antibody specificity. Each hybridoma produces a single, uniform monoclonal antibody.

Question 13

A person has used a path across their neighbor's land for $\text{20 years}$, openly, notoriously, and without the neighbor's permission. The person may have acquired:

An easement in gross.
An easement by prescription.✔️
Title by adverse possession.

Question 14

A document contains 2,048 bytes of data. How many bits does this document contain?

2,048 bits
4,096 bits
16,384 bits✔️
8,192 bits

Correct Answer Logic:

Since 1 byte = 8 bits: $2{,}048 \times 8 = 16{,}384$ bits. This conversion is essential when working with file sizes, network speeds (measured in bits per second), and storage capacities.

Chemistry QUESTION #7157

Question 15

The significant reducing ability of hypophosphorous acid ($H_{3}PO_{2}$) is primarily due to the presence of:

Two $P-OH$ bonds
One $P-H$ bond
Two $P-H$ bonds✔️
One $P-OH$ bond

Correct Answer Logic:

The reducing character of oxoacids of phosphorus depends on the number of $P-H$ bonds present. In $H_{3}PO_{2}$ (Hypophosphorous acid), the phosphorus atom is bonded to two hydrogen atoms directly ($2 \times P-H$ bonds) and one hydroxyl group ($1 \times P-OH$ bond). These $P-H$ bonds are responsible for its strong reducing property.
