Answer the question on the basis of passage given below:
Proteins are the polymers of about twenty different a-amino acids which are linked by peptide bonds. Proteins perform various structural and dynamic functions in the organisms. Proteins which contain only a-amino acids are called simple proteins. The secondary or tertiary structure of proteins get disturbed on change of pH or temperature and they are not able to perform their functions. This is called denaturation of proteins. Enzymes are biocatalysts which speed up the reactions in biosystems. Vitamins are accessory food factors required in the diet. They are classified as fat soluble (A, D, E and K) and water soluble (B group and C). Deficiency of vitamins leads to many diseases. Nucleic acids are the polymers of nucleotides which in turn consist of a base, a pentose sugar and phosphate moiety. Nucleic acids are responsible for the transfer of characters from parents to offsprings. There are two types of nucleic acids DNA and RNA. DNA contains a five carbon sugar molecule called 2-deoxyribose whereas RNA contains ribose.
RNA and DNA differ due to presence/absence of oxygen at which carbon of sugar moiety?

Answer the question on basis of passage given below :
Adsorption is surface phenomenon and it differs from absorption which occurs throughout the body of the substance which absorbs. In physisorption the attractive forces are mainly van der Waal forces while in chemisorption actual bonding occurs between the particles of adsorbent and adsorbed more easily on the surface of a solid as compared to the gases which are liquified with difficulty. Adsorption increases with the increases in pressure and decreases as temperature is increased
The effect of pressure on adsorption is high if

The statement "all tax payers above 60 years in India" is an example of

(B) Finite population
(C) Infinite population
(D) Statistical Interference

In the circuit shown below, \(C_1 = 6 \mu F\), \(C_2 = 3 \mu F\) and battery \(B = 40 V\). Initially, switch \(A_1\) is opened and the switch \(A_2\) is closed. Now switch \(A_2\) is opened and \(A_1\) is closed. The charge on \(C_2\) will be

Arrange the given steps of decomposition cycle in a terrestrial ecosystem in correct sequence?
(A) Bacterial and fungal enzymes degrade detritus into simpler a inorganic substances and its catabolism.
(B) Earthworms break-down detritus into smaller particles and is called fragmentation.
(C) Leaching - water soluble inorganic nutrients go down into the soil horizon.
(D) Microbes release inorganic nutrients in the soil and it is called mineralisation.
