Answer 2

HELLO MATE.....

Answer:

1. Some microbes, such as viruses, are even acellular (not composed of cells). Microorganisms are found in each of the three domains of life: Archaea, Bacteria, and Eukarya.
2. The fermentation of lactose by bacteria called “yogurt cultures” produces lactic acid, which helps in the formation of yogurt. ... Hence the process of making curd from milk using lactic acid bacteria is called curdling, while yogurt is formed by fermentation of lactobacillus bacteria.
3. The main use is that a fungi name penicillium notatum use for making medicene peniciline. Fungi are important as they can be used to decompose dead matter. It can help destroy green flies. It can also be useful for making citric acid, antibiotics and they can be useful for food e.g. wine, beer and bread.
4. Fermentation is the process in which a substance breaks down into a simpler substance. Microorganisms like yeast and bacteria usually play a role in the fermentation process, creating beer, wine, bread, kimchi, yogurt and other foods. Fermentation comes from the Latin word fermentare, meaning “to leaven.”
5. Antibiotics are powerful medicines that fight certain infections and can save lives when used properly. ... The first antibiotic was penicillin. Penicillin-based antibiotics, such as ampicillin, amoxicillin, and penicillin G, are still available to treat a variety of infections and have been around for a long time.
6. They are grouped into various groups like Bacteria, fungi, algae, protozoa and viruses. Many of these organisms are useful to human and nature.
7. List of Communicable Diseases--•CRE.•Ebola.•Enterovirus D68.•Flu.•Hantavirus.•Hepatitis A.•Hepatitis B.•HIV/AIDS.
8. Malaria is caused by Plasmodium parasites. The parasites are spread to people through the bites of infected female Anopheles mosquitoes, called "malaria vectors." There are 5 parasite species that cause malaria in humans, and 2 of these species – P. falciparum and P. vivax – pose the greatest threat.
9. Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.
