Answer:
eukaryotic
Explanation:
Fungi (or Mushrooms) are eukaryotic and have a complex cellular organization.
Algae are eukaryotic cells, or cells that contain a nucleus, which makes them slightly more complex than bacteria
Protozoa are single-celled eukaryotic (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy.
the right answer is by diffusion across a capillary wall
The period during which the presence of stromatolites decline is the Proterzoic period. Stromatolites are widely distributed sedimentary structures consisting of laminated carbonate or silicate rocks, produced over geologic time by the trapping, binding, or the precipitating of sediment by groups of microorganisms, primarily cyanobacteria.
