Organisms are found by complex combinations of non-living things. For this complex combination, there are some new properties are formed in organisms. Through non-living things that have an impact on the formation of organisms, these new properties are absent in non-living things. So, the properties of organisms differ from non-living things though non-living things have … Read more
Microbiology discusses the structure, biological functions, life cycle, and reproduction of different microorganisms like viruses, bacteria, fungi, etc. along with their produced diseases and their prevention. Besides, since it deals with ways to deal with the prevention of diseases produced by microorganisms through antibiotics and vaccines produced by microorganisms and their application in genetic technology … Read more
