Antibiotics have greatly improved our capacity to treat deadly diseases such as plague, whooping cough (kali khansi), diphtheria (gal ghotu) and leprosy (kusht rog), which used to kill millions all over the globe.
Streptokinase produced by the bacterium Streptococcus and modified by genetic engineering is used as a 'clot buster' for removing clots from the blood vessels of patients who have undergone myocardial infarction leading to heart attack. Microbes are diverse-protozoa, bacteria, fungi and microscopic animal and plant viruses, viroids and also prions that are proteinacious infectious agents. The puffed-up appearance of dough is due to the production of CO₂ gas. Similarly the dough, which is used for making bread, is fermented using baker's yeast (Saccharomyces cerevisiae). Primary sewage treatment basically involve physical removal of particles - large and small from the sewage through filtration and sedimentation. These are removed in stages; initially, floating debris is removed by sequential filtration. Then the grit (soil and small pebbles) are removed by sedimentation. All solids that settle form the primary sludge, and the supernatant forms the effluent. The effluent from the primary settling tank is taken for secondary treatment. The primary effluent is passed into large aeration tanks, where it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs. While growing, these microbes consume the major part of the organic matter in the effluent.
Prions are made up of :

A plane E-M wave of frequency 48 MHz travels in free space along the positive x-direction. At a particular point in space and time \( \vec{E} = 10.2\hat{j} \text{ V/m} \). The corresponding magnetic field \( \vec{B} \) at that point will be:

Which one of the following 1 molal aqueous solutions will show maximum freezing point depression?

In an experiment, a student measures the terminal potential difference (\( V \)) of a cell (emf \( E \) and internal resistance \( r \)) as a function of current \( I \) and plots a graph with \( V \) on the y-axis and \( I \) on the x-axis.
The slope of the graph between \( V \) and \( I \) is:

The value of k for which \(k \frac{d y}{d x}=\sqrt{x}-\frac{1}{\sqrt{x}}\), where \(y=\sqrt{x}+\frac{1}{\sqrt{x}}\); is :
