In a group of mushrooms exposed to a poisonous chemical, only a few of the mushrooms survived. The best explanation for the resistance of the surviving mushrooms is that the resistance
resulted from the presence of mutations in the mushrooms
a lack of genetic variability in the species
offspring with more variety
