Options:
A Kingdom, phylum, class, order, family, genus and species.
B Kingdom, phylum, class, order, family, species and genus.
C Kingdom, phylum, class, species, order, family and genus.
D Kingdom, species, phylum, class, order, family and genus.

The correct answer is:
Kingdom, phylum, class, order, family, genus and species.

Solution:
Taxonomy is the branch of biological science which includes nomenclature and classification of the organisms into groups based on their shared features and characteristics.
Classification is the process of grouping organisms based on observable features in to categories called 'taxa'. This process involves hierarchy of steps where each taxa represents a rank. All the steps/taxon collectively is referred as taxonomic hierarchy. The ranks/taxa have the following sequence from largest to the smallest with similarities in organisms increasing at each step. Kingdom, phylum, class, order, family, genus and species form the hierarchy in classification where Kingdom is the largest rank and species is the lowest with maximum similarities.

What is the correct order of osmotic pressure of 0.01M aqueous solution of
(1) Al2(SO4)3
(2) K3PO4
(3) BaCl2
(4) Urea

Options:
A π4>π3>π2>π1
B π1>π2>π3>π4
C π1=π2=π3=π4
D π2>π4>π1>π3

What is the correct order of the stages during aerobic respiration?

Options:
A Kreb's cycle - Electron transport chain - Glycolysis
B Electron transport chain - Krebs' cycle - Glycolysis
C Glycolysis - Krebs' cycle - Electron transport chain
D Glycolysis - Electron transport chain - Krebs' cycle

The correct answer is:
Glycolysis - Krebs' cycle - Electron transport chain

Solution:
Cellular respiration is the process in which energy stored in a glucose molecule is released by oxidation. During glycolysis, glucose is broken down into two molecules of pyruvate, which due to link reaction, get converted into acetyl CoA. This acetyl CoA enters the Kreb's cycle and gets converted into CO2 producing NADH2 and FADH2. This NADH2 and FADH2 are oxidized through oxidative phosphorylation to regenerate NAD and FAD and produce ATP.

What is the correct relationship between the $\mathrm{pHs}$ of isomolars solution of sodium oxide $\left(\mathrm{pH}_1\right)$, sodium sulphide $\left(\mathrm{pH}_2\right)$, sodium selenide $\left(\mathrm{pH}_3\right)$ and sodium telluruide $\left(\mathrm{pH}_4\right)$ ?

Options:
A $\mathrm{pH}_1>\mathrm{pH}_2>\mathrm{pH}_3>\mathrm{pH}_4$
B $\mathrm{pH}_1>\mathrm{pH}_2=\mathrm{pH}_3>\mathrm{pH}_4$
C $\mathrm{pH}_1 < \mathrm{pH}_2 < \mathrm{pH}_3 < \mathrm{pH}_4$
D $\mathrm{pH}_1 < \mathrm{pH}_2 < \mathrm{pH}_3=\mathrm{pH}_4$

The correct answer is:
$\mathrm{pH}_1>\mathrm{pH}_2>\mathrm{pH}_3>\mathrm{pH}_4$

Solution:
It is given that the isomolar solutions are sodium salt of Group 16 elements are present in equal molar concentration. The salts on hydrolysis with water, it produces an acid and base, as follows:
I. $\mathrm{Na}_2 \mathrm{O}+\mathrm{H}_2 \mathrm{O} \longrightarrow 2 \mathrm{NaOH}$
II. $\mathrm{Na}_2 \mathrm{~S}+\mathrm{H}_2 \mathrm{O} \longrightarrow 2 \mathrm{NaOH}+\mathrm{H}_2 \mathrm{~S}$
III. $\mathrm{Na}_2 \mathrm{Se}+\mathrm{H}_2 \mathrm{O} \longrightarrow 2 \mathrm{NaOH}$ $+\mathrm{H}_2 \mathrm{Se}$
IV. $\mathrm{Na}_2 \mathrm{Te}+\mathrm{H}_2 \mathrm{O}>2 \mathrm{NaOH}$ $+\mathrm{H}_2 \mathrm{Te}$
The acidic strength of the hydrides is in the order $\mathrm{H}_2 \mathrm{O} < \mathrm{H}_2 \mathrm{~S} < \mathrm{H}_2 \mathrm{Se} < $ $\mathrm{H}_2 \mathrm{Te}$, due to increase in the atomic size.
As the acidic character of the hydride increases down the group, the basic character of the salt decreases down the group. Therefore, the order of basic character of the salts will be: $\mathrm{Na}_2 \mathrm{O}>\mathrm{Na}_2 \mathrm{~S}>\mathrm{Na}_2 \mathrm{Se}>\mathrm{Na}_2 \mathrm{Te}$
Therefore, the order of $\mathrm{pH}$ of the given aqueous solution is $\mathrm{pH}_1>\mathrm{pH}_2>$ $\mathrm{pH}_3>\mathrm{pH}_4$
Related Theory
The $\mathrm{pH}$ of the isomolar solution, can be determined with respect to the basic character of the sodium salts of the Group 16 elements. These salts undergo hydrolysis, forming hydrides, whose acidic character can account for the basic character of the salt, formed through neutralisation.
A Caution
In the reverse reaction of neutralisation, from the acidic strength of the hydrides, we can obtain the order of ease of neutralisation of the sodium hydroxide with the hydrides. As more the acidity of the hydride, more will be the neutralisation to form the salt.

What is the correct sequence of the increasing basic nature of the given oxides?

Options:
A K 2 O<N a 2 O<A l 2 O 3 <MgO
B A l 2 O 3 <MgO<N a 2 O< K 2 O
C MgO< K 2 O<A l 2 O 3 <N a 2 O
D MgO< K 2 O<N a 2 O<A l 2 O 3

The correct answer is:
A l 2 O 3 <MgO<N a 2 O< K 2 O

Solution:
Basic nature is directly proportional to the metallic nature.

Metallic nature is inversely proportional to the ionisation enthalpy.

Lesser the ionisation enthalpy, ease of donation of electron and more metallic character due to this most basic oxide will form.

Most metallic oxides are the alkali metal oxides like K 2 O and Na 2 O are more basic than the MgO because magnesium belongs to the alkaline earth metals and it is less metallic than the alkali metals.

Al 2 O 3 belongs to the amphoteric oxides p-block metal.

Therefore the correct order of the basic strength of the oxides is

A l 2 O 3 <MgO<N a 2 O< K 2 O

What is the criterion for DNA fragments movement on agarose gel during gel electrophoresis?

Options:
A The smaller the fragment size, the farther it moves.
B Positively charged fragments move to farther end.
C Negatively charged fragments do not move.
D The larger the fragment size, the farther it moves.

The correct answer is:
The smaller the fragment size, the farther it moves.

Solution:
Gel electrophoresis was developed by Tiselius and is based on the principal that charged molecules move to electrode of opposite charge when placed in electric field and the movement depends on the charge and size of the molecule.
Due to the sieve-like texture of the gel, smaller DNA fragments travel faster toward the electrode than the larger fragments.
