A fungus and an algae grow together to produce what we call a lichen. When investigators separate out the fungus from the alga and try to grow them in the same habitat but each alone, they all die. What hypothesis most logically explains this phenomenon? Ans: The fungus and the algae have a mutualistic relationship. They only survive when they are together because each organism benefits from their interaction, thus when they are separated they do not get the benefits as when they ar...

Microorganisms are classified in various taxonomic categories: they can be prokaryotic (bacteria and archaea); or eukaryotic (animals, plants, protists, fungi). While virus, viroids, and other infectious agents such as prions are also microscopic, they are not considered living organisms because they are acellular (lacking a cell). Unicellular organisms (prokaryotes and eukaryotes) and many multicellular organisms (eukaryotes) are microscopic living organisms. An instrument called a ___...
