Match List-I with List-II relating to microbes and their products: List-I (Microbes) A. Streptococcus B. Trichoderma polysporum C. Monascus purpureus D. Aspergillus niger List-II (Products) I. Citric acid II. Clot buster III. Cyclosporin A IV. Statins
An air bubble in a glass slab with refractive index 1.5 (near normal incidence) is $5\text{ cm}$ deep when viewed from one surface and $3\text{ cm}$ deep when viewed from the opposite face. The thickness (in cm) of the slab is:
Two similar thin equi-convex lenses, of focal length $f$ each, are kept coaxially in contact with each other such that the focal length of the combination is $F_1$. When the space between the two lenses is filled with glycerin which has the same refractive index as that of glass ($\mu = 1.5$), then the equivalent focal length is $F_2$. The ratio $F_1 : F_2$ will be:
In a p-n junction diode, the change in temperature due to heating:

For a biocontrol agent to be part of an integrated pest management, it should be:
Which of the following alkane cannot be made in good yield by Wurtz reaction?
In an astronomical telescope in normal adjustment, a straight black line of length $L$ is drawn on the inside part of the objective lens. The eye-piece forms a real image of this line. The length of this image is $l$. The magnification of the telescope is:
Which set of colours would be observed in the air under the conditions depicted in the figure?
Match List I with List II: List I A. Clostridium butylicum B. Saccharomyces cerevisiae C. Trichoderma polysporum D. Streptococcus sp. List II I. Ethanol II. Streptokinase III. Butyric acid IV. Cyclosporin-A

A good producer of citric acid is:
In total internal reflection when the angle of incidence is equal to the critical angle for the pair of media in contact, what will be the angle of refraction?
The figure shows a logic circuit with two inputs $A$ and $B$ and the output $C$. The voltage waveforms across $A$, $B$ and $C$ are as given. The logic circuit gate is:
Which of the following in sewage treatment removes suspended solids?
Trichoderma harzianum has proved to be a useful micro-organism for:
Cyclosporin A, used as an immuno-suppression agent, is produced from:
Given below are two statements: Statement I: Bacterial infection by Bacillus thuringiensis can kill only caterpillar larvae. Statement II: B. thuringiensis cannot kill adult moths. In light of the above statements, choose the most appropriate answer from the options given below:
Two amplifiers of voltage gain $20$ each, are cascaded in series. If $0.01\text{ V}$ a.c. input signal is applied across the first amplifier, the output a.c. signal of the second amplifier in volts is:
If the initial tension on a stretched string is doubled, then the ratio of the initial and final speeds of a transverse wave along the string is
