Use of moist heat can control microbial growth in many circumstances, but heat-sensitive items and those susceptible to moisture cannot be sterilized in this manner. which of the following correctly describes a method of physical control used to control microbial growth on or in such items?
select all that apply.

filtration is the passage of a liquid or a gas through a screenlike material with pores small enough to retain microorganisms. a vacuum is typically used to force the liquid through the mesh, and then the sterile liquid or gas is collected in a sterile container on the other side.
nonionizing radiation, such as uv light, has a wavelength longer than that of ionizing radiation. the wavelengths of uv light are absorbed by cellular dna in organisms directly exposed to the light.
desiccation is a process that removes water from microorganisms, leaving them unable to grow or reproduce, but still viable.
osmotic pressure is a process that uses high concentrations of salts and sugars to preserve food.
