Answer 1

1. The microbiology is the study of microbes or microorganisms which are basically any organism too small to be seen by the naked eye. Microbiology encompasses several other sub-disciplines including immunology, virology, bacteriology, along with mycology, protistology, parasitology etc.

2. The general microbiology lab cultures, manipulates, and uses virulent and/or potentially pathogenic microorganisms. So, there may be a chance of infection if the precautions and safety measures are not followed properly. So, the general microbiology lab is a safe environment but only for trained personnel or individual who follow the safety measures and precautions properly.

3. No. Though proper steps are taken to sterile the microbiology lab as much as possible, but it should be remembered that a completely sterile working environment does not exist. So, it is impossible to get a complete aseptic environment in the microbiology lab. That's why, to get a adequate sterile environment where the microbiological work can be done without contamination, the laminar air hood is taken into account, which is basically an apparatus with a chamber that is adequately steriled using UV light and hepa filter.

4. All of the above options are correct. It is important to be able to culture the microorganisms to identify them, to study their metabolism and genetics, and to learn how to manipulate and control their growth.
