Biology Zoology Botany QUESTION #1392

In which part of the plant does the Calvin cycle occur?

Stroma of chloroplasts✔️
Thylakoid membrane
Cytoplasm
Nucleus

Correct Answer Logic:

The Calvin cycle (light-independent reactions / dark reactions) takes place in the stroma of chloroplasts — the fluid-filled space surrounding the thylakoids. Here, CO$_2$ is fixed using ATP and NADPH (produced in the light reactions on the thylakoid membranes) to synthesise glucose via the enzyme RuBisCO. The light reactions occur on the thylakoid membranes.

Electronics Engineering QUESTION #11714

Question 386

A directional coupler has a coupling factor of $-20\,\text{dB}$ and directivity of $30\,\text{dB}$. The isolation between the input and isolated port is:

$10\,\text{dB}$
$30\,\text{dB}$
$50\,\text{dB}$✔️
$20\,\text{dB}$

Correct Answer Logic:

Isolation = Coupling + Directivity $= 20\,\text{dB} + 30\,\text{dB} = \mathbf{50\,\text{dB}}$. Coupling factor is the power tapped to the coupled port; directivity is the ability to discriminate between forward and reverse waves at the coupled port; isolation is the total suppression of backward signal at the isolated port.

Which environmental condition is considered most damaging to the long-term preservation of rare books and manuscripts?

Cool temperatures between 15–18°C
Fluctuating temperature and high relative humidity (above 65%)✔️
Dim, ultraviolet-filtered lighting
Acid-free storage boxes

Correct Answer Logic:

Fluctuating temperature and high relative humidity (above 60–65%) are the most destructive environmental conditions for rare materials — accelerating acid hydrolysis, mold growth, and insect infestation. Stable cool temperatures and controlled humidity (45–55% RH) are the recommended preservation standards.

Mathematics QUESTION #6982

Question 393

Two cards are drawn one after another with replacement from a well-shuffled standard deck of 52 cards. Let $X$ be the number of aces obtained. Find $P(X=1)+P(X=2)$.

$\dfrac{49}{169}$
$\dfrac{52}{169}$
$\dfrac{24}{169}$
$\dfrac{25}{169}$✔️

Correct Answer Logic:

$p=P(\text{ace})=\dfrac{4}{52}=\dfrac{1}{13}$, $q=\dfrac{12}{13}$. Binomial with $n=2$.

$P(X=1)=\binom{2}{1}\cdot\dfrac{1}{13}\cdot\dfrac{12}{13}=\dfrac{24}{169}$

$P(X=2)=\binom{2}{2}\cdot\left(\dfrac{1}{13}\right)^2=\dfrac{1}{169}$

$P(X=1)+P(X=2)=\dfrac{24}{169}+\dfrac{1}{169}=\dfrac{25}{169}$
