Quizplus · Accepted Answer

An artifact refers to any structure that is visible in an electron micrograph but is not present in the original specimen. These can arise due to a variety of factors, such as staining or sample preparation techniques. Antigen refers to a foreign substance that induces an immune response, biofilm is a community of microorganisms that adhere to surfaces, refraction is the bending of light as it passes through different media, and mordant refers to a substance used in staining to fix or enhance the color of the specimen.
