Question

Good morning everyone..

Give Answer this two questions..

1. List the usefulness of microorganisms is our lives.
2. How are the actions of microorganisms useful and harmful for us?​

Answer 1

Explanation:

1. They are used in winemaking, baking, pickling and other food-making processes.
3. Alcoholic fermentation by yeast is widely used in the preparation of wine and bread.
5. A bacterium Lactobacillus promotes the formation of curd.
7. Microbes are used to reduce pollution.
9. They are used to increase soil fertility by fixing atmospheric nitrogen.
11. Microbes are also useful in preparing many medicines and antibiotics.
13. Certain microbes are also used in the biological treatment of sewage and industrial effluents.
15. Some microorganisms are taken as probiotics, that are believed to provide health benefits when consumed.
17. Bacteria are also involved in making cheese.
19. Acetobacter acetic is used for producing acetic acid from alcohol
20. Microbes run the world. It's that simple.” (Committee on Metagenomics, 2007 blue right-pointing triangle). Microbial communities make the essential elements of oxygen, carbon, nitrogen, and sulfur available for other life on our planet. Without microbial decomposer communities, life would be smothered in dead organisms. Microorganisms also carry out almost half of the photosynthesis on our planet, increasing oxygen levels and lowering carbon dioxide (Pedros-Alio, 2006 blue right-pointing triangle). Both animals and plants are closely associated with microbial communities that make nutrients more available, provide protection from diseases, make essential vitamins, or a combination. For example, each human body hosts 10 microorganisms for every human cell, and these microbes contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals. And, of course, microbes are essential to making many foods we enjoy, such as bread, cheese, and wine.
22. Unfortunately, students often think of microorganisms in negative terms. Negative attitudes are supported by the public health and media focus on microbe-caused diseases as well as advertising for microbe-destroying soaps and cleaners. Although reducing disease transmission is important for individual and community health, students also need to understand the beneficial contributions microbes and microbial communities provide. Quite a few online resources focus on microorganisms and disease. For this review, I sought resources that educators can use to help students in introductory and nonmajors biology courses understand the beneficial contributions of microbes.
23. I am fine dear hw r u

Answer 2

1. (i) Microorganisms help us in food sector. They are used for curdling of milk, preparation of bread, cake, etc. ... (vii) Microorganisms are used to prepare vaccines for various diseases. (viii) They are useful for agriculture sector, as they enhance the fertility of soil by fixing nitrogen.
