significance in commercial products such as cheese and yogurt
sewage disposal
nitrogen fixation
Answer: All the four
Bacteria are single celled simple prokaryotic organisms. They perform different roles in nature:
1. decomposition: It is a process in which the complex organic matter from dead remains of plants and animals is converted into simple molecules. Many bacterial agents participate in this process, in order to obtain their nourishment. Decomposition is a natural waste management process.
2.significance in commercial products such as cheese and yogurt: Bacterial strain named as Lactobacillus is used in dairy products like cheese and yogurt. Bacteria are used to make organic acids in pickles and vinegar. Sourdough bread is made by the fermentation process of the yeast and bacteria is also used as an ingredient.
3.sewage disposal: The decomposing nature of the bacteria facilitates the degradation of organic waste present in the sewage. Therefore, they help in sewage waste management or disposal.
4. nitrogen fixation: Some bacteria lives in symbiotic relationship with plants, especially with leguminous plants. The bacteria trap the atmospheric nitrogen from the environment and supply it to plants, which is necessary for growth, in return the bacteria receives nutrition from plants.
Therefore, all the four options are correct.

Answer:
C) isopropyl alcohol and chlorhexidine gluconate
Explanation:
The World Health Organization (WHO) guidelines mandate that the venipuncture site be cleaned with an alcohol swab of 70 percent alcohol.
Document H3-A6 is also recommended by the Clinical and Laboratory Standards Institute (CLSI) that skin disinfection with 70% isopropyl alcohol or ethanol is required before venipuncturing tosterile the skin surface. chlorhexidine gluconate is a good repacment of isopropyl alcohol, hence used at venipuncture site.
Hence, the correct option is C.
