Read the following passage carefully and answer the given questions.
Bioactive molecule, cyclosporin A, that is used as an immunosuppressive agent in organ-transplant patients, is produced by the fungus Trichoderma polysporum. Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents. It acts by competitively inhibiting the enzyme responsible for synthesis of cholesterol. Baculoviruses are pathogens that attack insects and other arthropods. The majority of baculoviruses used as biological control agents are in the genus Nucleopolyhedrovirus. These viruses are excellent candidates for species-specific, narrow spectrum insecticidal applications. They have been shown to have no negative impacts on plants, mammals, birds, fish or even on non-target insects. BOD refers to the amount of the oxygen that would be consumed if all the organic matter in one liter of water were oxidised by bacteria. The sewage water is treated till the BOD is reduced. Cheese, is one of the oldest food items in which microbes were used. Different varieties of cheese are known by their characteristic texture, flavour and taste. For example, the large holes in ‘Swiss cheese’ are due to production of a large amount of CO₂ by a bacterium named Propionibacterium sharmanii.

A small standing crop of phytoplankton supports a large standing crop of zooplankton. This can be correctly represented by:

Read the paragraph given below and answer the question.
Insulin used for diabetes was earlier extracted from slaughtered cattle and pigs. Insulin from an animal source, though caused some patients to develop allergy or other type of reactions. Insulin consists of two short polypeptide chains: chain A and chain B, that are linked bridges. In mammals, including human, insulin is synthesised as a pro-hormone.
Bonds which link 'A' and 'B' peptide chains of human insulin are

A lens is formed by placing the plane faces of two identical plano-convex lenses (each of focal length 40 cm) touching each other. It is used to obtain a real, inverted image of the same size as the object. The distance of the object from the lens is:

The process used for the conversion of sugar into Ethanol is :

If \(x y+\frac{x^2}{y}=x^3 y+y\), then \(\frac{d y}{d x}\) is equal to

Find the least non-negative remainder obtained when \(3^{128}\) is divided by \(7\) .

Embryological support for evolution was proposed by :

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
