1. Chloramine-T is an
Answer: (a); Disinfectants are chemical agents designed to inactivate or destroy microorganisms on inert surfaces. Disinfectants work by destroying the cell wall of microbes or interfering with their metabolism. It is also a form of decontamination, and can be defined as the process whereby physical or chemical methods are used to reduce the amount of pathogenic microorganisms on a surface. Disinfectants are frequently used in hospitals, dental surgeries, kitchens, and bathrooms to kill infectious organisms. Sanitizers/ antiseptic are mild compared to disinfectants and are used majorly to clean things which are in human contact whereas disinfectants are concentrated and are used to clean surfaces like floors and building premises.
- Glycols are effective air disinfectants in controlled laboratory environments.
- Alcohol and alcohol plus Quaternary ammonium cation based compounds comprise a class of proven surface sanitizers and disinfectants
- Aldehydes, such as formaldehyde and glutaraldehyde, have a wide microbicidal activity and are sporicidal and fungicidal.
- Oxidizing agents act by oxidizing the cell membrane of microorganisms, which results in a loss of structure and leads to cell lysis and death. A large number of disinfectants operate in this way. chlorine water, high voltage electrolyzed water, hydrogen peroxide, ozone, Potassium permanganate (KMnO4)
- Peroxycarboxylic acids and inorganic peroxo acids are strong oxidants and extremely effective disinfectants. Peroxyformic acid, Peracetic acid, Peroxypropionic acid, Monoperoxyglutaric acid. Monoperoxysuccinic acid, Peroxybenzoic acid, Peroxyanisic acid, Chloroperbenzoic acid, Monoperoxyphthalic acid, Peroxymonosulfuric acid
- Phenolics are active ingredients in some household disinfectants. o-Phenylphenol, Chloroxylenol, Hexachlorophene Thymol, Amylmetacresol, 2,4-dichlorobenzyl

3. Interferon is connected with
- ore of iron
Answer: (b) Interferons are a group of signaling proteins made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.
