Osmotic pressure is the pressure that stops the flow of a solvent and is related to the volume as:

Pentan-2-one and pentan-3-one can be distinguished by

Answer the question on basis of passage given below :
Molecular nitrogen is very little reactive chemically. During lightning discharge, atmospheric nitrogen and oxygen combines to form nitric oxide which also combines with oxygen to form nitrogen dioxide. Both NO and \(NO _2\) constitute smog which is very poisonous. It can cause burning sensation in the eyes and adversely affect respiratory system.
Oxidation state of nitrogen in nitric oxide and nitrogen dioxide respectively is :

The IUPAC name of the following compound is

Number of unpaired electrons in the square planar [Pt(CN)₄]^2- are :

The limiting molar conductivities for \(NaCl\), \(HCl\) and \(CH_3COONa\) are \(126.4\), \(425.9\) and \(91.0\ S\ cm^2\ mol^{-1}\), respectively. Calculate the limiting molar conductivity for acetic acid.

The points on the curve \(\frac{x^2}{9}+\frac{y^2}{16}=1\) at which the tangents are parallel to \(x\) - axis are:

If a line makes angles \(\alpha, \beta\) and \(\gamma\) with positive \(x\)-axis, \(y\)-axis and \(z\)-axis respectively, then the value of \(\sin ^2 \frac{\alpha}{2} \cos ^2 \frac{\alpha}{2}+\sin ^2 \frac{\beta}{2} \cos ^2 \frac{\beta}{2}+\sin ^2 \frac{\gamma}{2} \cos ^2 \frac{\gamma}{2}\) is

The value of \(\int_1^2 \frac{\sqrt{x}}{\sqrt{3-x}+\sqrt{x}} d x\) is:

There are two kinds of nucleases - exonucleases and endonucleases. Exonucleases remove nucleotides from the ends of the DNA whereas, endonucleases make cuts at specific positions within the DNA. The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis. Since DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix. Small volume cultures cannot yield appreciable quantities of products. To produce in large quantities, the development of bioreactors, where large volumes (100 - 1000 litres) of culture can be processed, was required. Thus, bioreactors can be thought of as vessels in which raw materials are biologically converted into specific products, individual enzymes, etc., using microbial plant, animal or human cells. PCR stands for Polymerase Chain Reaction. In this reaction, multiple copies of the gene (or DNA) of interest are synthesised in vitro using two sets of primers (small chemically synthesised oligonucleotides that are complementary to the regions of DNA) and the enzyme DNA polymerase.
Identify the incorrect fact about the PCR?

Read the passage carefully and give the answers to the question :
India was amongst the first countries in the world to initiate action plans and programmes at a national level to attain total reproductive health as a social goal.
These programmes called 'family planning' were initiated in 1951 and were periodically assessed over the past decades. Improved programmes covering wider reproduction-related areas are currently in operation. Creating awareness among the people about various reproduction-related aspects and providing facilities and support for building up a reproductively healthy society are the major tasks under these programmes.
'Saheli' - an oral contraceptive pill, also known as the 'Once a week' pill, was developed by :
