microorganiams are very harmful forces so we have to kill them do you agree with this?explain with examples
Answers
Answer:
No all the microorganisma aren't harmful... Some are present in our hands naturally and help us digest food... But usage of soaps and other things kill them causing harm to us... Hope hlpzzz
Answer:
Microorganisms
Microorganisms is a broad term used to encompass bacteria, yeast, fungi, and in some definition viruses. The classification is broad and includes both microorganisms that are capable of replication outside of any host and those that require a host to survive. They range in size from less than 100 nm to almost a millimeter, the latter exemplified by Thiomargarita namibiensis which is approximately 750 μm in length (Schulz and Jørgensen, 2001). The further classification of microorganisms can be rooted in a number of different frameworks but with the advent of DNA sequencing, a common framework has evolved to allow for relationships to be built across all of these different microorganisms. That framework based upon rRNA has given rise to the ‘tree of life’ a popular representation of all living organisms (except for viruses) (Figure 1). Within this framework, the relationship between man and the microorganisms that inhabit the Earth and our bodies can be examined.
Different ways to kill microorganisms are as follows:
1. Heat (Temperature) Sterilization:
Fire and boiling water have been used for sterilization and disaffection since the time of the Greeks, and heating is still one of the most popular ways to kill microorganisms. Microorganisms grow over a wide range of temperatures, and every type of them has an optimum, minimum and maximum growth temperature.
Temperatures above the maximum generally kill microorganisms subject to the fact that the parameters that influence heat (temperature) sterilization are favourable. However, heat is employed either in dry state (dry heat sterilization) or in moist state (moist heat sterilization). High heat combined with high moisture is one of the most effective methods of killing microorganisms.
2. Radiation: Radiation from radioactive substances also lead to killing of microorganisms.
3. Chlorination: In this process chlorine is added to water to kill microorganisms.
