Solution

Ans. Pasteurization is a process in which haet processing of liquid or food is done to kill harmful pathogens to make it fit for consuming. Pasteurization helps in killing pathogenic bacteria which ultimately reduces the chances to cause the disease.

Sterilization is a process that is used to deactivate the biological forms suvh as bacteria, virus etc

Sterilization could be done by heat, chemical , radiation, filtration etc

Disinfectants are antimicrobial agent usually chemicals that is used to kill the pathogenic microorganisms

2. Sepsis is a lifethreatning illness that is caused due to our body response to infection.

5. Moist heat can causes destruction of micro-organisms by denaturation of macromolecules, primarily proteins. Destruction of cells by lysis may also play a role. While \"sterility\" implies the destruction of free-living organisms which may grow within a sample, sterilization does not necessarily entail destruction of infectious matter. Prions are an example of an infectious agent that can survive sterilization by moist heat, depending on conditions. Moist heat can protein us from prion disease.
