What is the role-played by luteinising hormones in males and females respectively.

Options:

None

Solution:
LH and FSH stimulate activity of gonads and hence are called gonadotropins.
Luteinising hormone $(\mathrm{LH})$ in males stimulates the synthesis and secretion of hormones called androgens from testis. Androgens along with FSH (Follicle Stimulating Hormone) regulate spermatogenesis.
LH induces ovulation of fully mature follicles in females and maintains the corpus luteum, formed from the remnants of the graafian follicles after ovulation. This secretes progesterone.

What is the set of all points, where the function
$f(x)=\frac{x}{1+|x|}$ is differentiable?

Options:
A $(-\infty, \infty)$ only
B $(0, \infty)$ only
C $(-\infty, 0) \cup(0, \infty)$ only
D $(-\infty, 0)$ only

The correct answer is:
$(-\infty, \infty)$ only

Solution:
Given $f(x)=\frac{x}{1+|x|}$
$=\left\{\begin{array}{c}\frac{x}{1-x}, x < 0 \\ \frac{x}{1+x}, x \geq 0\end{array} \quad\left(\because|x|=\left\{\begin{array}{lll}x & \text { if } \quad x \geq 0 \\ -x & \text { if } \quad x < 0\end{array}\right)\right.\right.$
$\therefore \quad$ LHD $=f^{\prime}\left(0^{-}\right)=\lim _{h \rightarrow 0} \frac{f(0-h)-f(0)}{-h}$
$=\lim _{h \rightarrow 0} \frac{f(-h)-f(0)}{-h}$
and $\mathrm{RHD}=f^{\prime}\left(0^{+}\right)$
$=\lim _{h \rightarrow 0} \frac{f(0+h)-f(0)}{h}$
$\quad$ Since, $\mathrm{LHD}=\mathrm{RHD}$
$\therefore \quad f(x)$ is differentiable at $x=0$
Hence, $f(x)$ is differentiable in $(-\infty, \infty)$.

What is the significance of leaching in the extraction of aluminium?

Options:

None

Solution:
Aluminium contains silica \(\left(\mathrm{SiO}_2\right)\), iron oxide \(\left(\mathrm{Fe}_2 \mathrm{O}_3\right)\) and titanium oxide \(\left(\mathrm{TiO}_2\right)\) as impurities. These impurities can be removed by the process of leaching. During leaching, the powdered bauxite ore is heated with a concentrated \((45 \%)\) solution of \(\mathrm{NaOH}\) at \(473-523 \mathrm{~K}\), where alumina dissolves as sodium meta-aluminate and silica as sodium silicate leaving \(\mathrm{Fe}_2 \mathrm{O}_3, \mathrm{TiO}_2\) and other impurities behind :
\(\mathrm{Al}_2 \mathrm{O}_3(s)+2 \mathrm{NaOH}(a q)+3 \mathrm{H}_2 \mathrm{O}(l) \stackrel{473-523 \mathrm{~K}}{\longrightarrow} \underset{\text{Sodium meta-aluminate}}{2 \mathrm{Na}\left[\mathrm{Al}(\mathrm{OH})_4\right](a q)}\)
\(\mathrm{SiO}_2(s)+2 \mathrm{NaOH}(a q) \stackrel{473-523 \mathrm{~K}}{\longrightarrow} \underset{\text{Sodium silicate}}{\mathrm{Na}_2 \mathrm{SiO}_3(a q)}+\mathrm{H}_2 \mathrm{O}(l)\)
The impurities are filtered off and solution of sodium metaaluminate is neutralised by passing \(\mathrm{CO}_2\) when hydrated alumina separates out while sodium silicate remains in solution. The hydrated alumina thus obtained is filtered, dried and heated to give back pure alumina.
Thus, by leaching, pure alumina can be obtained from bauxite ore.

Options:

None

Solution:
The significance of meiosis :
1. It reduces the number of chromosomes to half in the daughter cells.
2. It is very essential phenomenon in the life cycle of sexually reproducing animals as it restores the fixed number of chromosomes present in the somatic cells, characteristic of the species.
3. Gametes are formed as a result of meiosis. Each gamete possesses half the number of chromosomes present in the somatic cells.
4. It avoids the multiplication of chromosomes and thus maintains the stability and constant number of chromosomes of the species.
5. During the crossing over exchange of nuclear material (genes) cause genetic variations within the species. As a result new combinations of hereditary material are formed.

Options:
A A2BC
B AB2C
C AB3C
D ABC2
