<span>The inheritance of a trait in humans is best described as being determined by one or more alleles </span>
Explanation:
nonliving characteristics include the fact that they are not cells have no cytoplasm or cellular organelles and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. And viruses can infect animals, plants and even other microorganisms.
I would say the temperature of a biome, and the precipitation (rain, snow, etc.). For example, a desert can obviously be classified for its immense amounts of heat and lack of rain. Hope this helps.
