Biology Zoology Botany QUESTION #1378

In dicot plants, the first leaf-like structure that emerges from the seed is called:

Hypocotyl
Cotyledon✔️
Epicotyl
Radicle

Correct Answer Logic:

Cotyledons are the seed leaves (embryonic leaves) present inside the seed. In dicots there are two cotyledons. They are the first leaf-like structures to emerge from a germinating seed and often serve as the primary source of nutrition for the seedling. The hypocotyl is the stem below cotyledons; epicotyl is above; radicle becomes the root.

Question 4703

If $\vec{a}\times(\vec{b}\times\vec{c}) = (\vec{a}\times\vec{b})\times\vec{c}$, what can be concluded about $\vec{a}$ and $\vec{c}$?

They are perpendicular
They are parallel✔️
Their magnitudes are equal
Their dot product is 1

Correct Answer Logic:

Expand both sides using the BAC-CAB rule. LHS: $\vec{b}(\vec{a}\cdot\vec{c})-\vec{c}(\vec{a}\cdot\vec{b})$. RHS: $\vec{a}(\vec{b}\cdot\vec{c})-\vec{b}(\vec{a}\cdot\vec{c})$. Setting equal and simplifying yields $(\vec{a}\times\vec{c})\times\vec{b}=\vec{0}$ for all $\vec{b}$, which implies $\vec{a}\times\vec{c}=\vec{0}$, meaning $\vec{a}$ and $\vec{c}$ are parallel.

Mathematics QUESTION #1321

Question 4710

The area enclosed between two curves $y=f(x)$ and $y=g(x)$ where $f(x)\geq g(x)$ on $[a,b]$ is given by:

$\int_a^b[f(x)+g(x)]\,dx$
$\int_a^b[f(x)-g(x)]\,dx$✔️
$\int_a^b[f(x)\cdot g(x)]\,dx$
$\dfrac{1}{2}\int_a^b[f(x)-g(x)]\,dx$

Correct Answer Logic:

The area between two curves is the integral of the top curve minus the bottom curve: $A=\int_a^b[f(x)-g(x)]\,dx$ where $f(x)\geq g(x)$ on $[a,b]$. The limits $a$ and $b$ are the $x$-coordinates of the intersection points.

Statistics QUESTION #2013

Question 4712

The relative efficiency (RE) of a Completely Randomized Design (CRD) relative to an RCB design is used to indicate:

Whether the F-test is significant
How many times more observations CRD would need to achieve the same precision as RCB✔️
The ratio of treatment means in both designs
The difference in error degrees of freedom between designs

Correct Answer Logic:

Relative efficiency $RE = \dfrac{MS_E(\text{CRD})}{MS_E(\text{RCB})}$ estimates how many times more replications a CRD would need to attain the same precision as the RCB design. An $RE > 1$ indicates blocking was effective in reducing error variance, justifying the use of the RCB design.

Mathematics QUESTION #1275

Question 4715

If $f(Z)=u+iv$ is analytic and $u(x,y)=\cos x\cosh y$, then $v(x,y)$ is:

$-\sin x\sinh y$
$\sin x\sinh y$✔️
$\cos x\sinh y$
$-\cos x\sinh y$

Correct Answer Logic:

Using C-R: $u_x=-\sin x\cosh y=v_y\Rightarrow v=\int-\sin x\cosh y\,dy...$ Alternatively, $u_y=\cos x\sinh y=-v_x\Rightarrow v_x=-\cos x\sinh y\Rightarrow v=\sin x\sinh y+g(y)$. Then $v_y=\sin x\cosh y=u_x$... Actually $v_y=-\sin x\cosh y$ from C-R. Integrating: $v=-\sin x\sinh y$. Wait: $u_x=-\sin x\cosh y=v_y\Rightarrow v=\int-\sin x\cosh y\,dy=-\sin x\sinh y$. Hmm, but then checking: $u_y=\cos x\sinh y$ must equal $-v_x=\cos x\sinh y$ ✓. So $v=-\sin x\sinh y$. However common result for this pair is $v=\sin x\sinh y$ when $u=\cos x\cosh y$. Recheck: $f(z)=\cos z=\cos(x+iy)=\cos x\cosh y - i\sin x\sinh y$. So $v=-\sin x\sinh y$. Answer: option (A).
