Question

Quizplus · Accepted Answer

Filtration takes advantage of the size of microorganisms by using a filter with pores small enough to trap and remove them from a liquid or gas. Autoclaving uses heat and pressure to kill microorganisms, open flame is a form of incineration that doesn't rely on size, and the use of chemicals may kill microorganisms but doesn't necessarily take advantage of their size.
