until the late 1970s, there was no \domain\ as the broadest category in taxonomy. instead, there were five kingdoms: protista, plantae, fungi, animalia, and monera, which included all bacteria - like organisms. researchers proposed the domains to distinguish between the bacteria - like organisms. which information supported placing bacteria and archaea in separate domains?
cell shapes of bacteria and archaea were found to be more distinct, after microscope technology improved.

Explanation:

1. For the first question, an organ is a structure made up of tissues that perform a specific function. A flower in plants and a liver in animals are examples of organs. A cell is the basic unit of life, an organelle is a sub - cellular structure, a population is a group of the same species, and a molecule is a group of atoms bonded together.
2. For the second question, bacteria and archaea have significant differences in their cell wall composition, membrane lipids, and genetic machinery. These differences are more fundamental than just cell shape and led to their separation into different domains.

Answer:

1. B. organ
2. None of the provided options are correct as the main information supporting the separation of bacteria and archaea into different domains is differences in cell - wall composition, membrane lipids, and genetic machinery rather than just cell shape.
