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.
Unduplicated chromosomes are single chromosomes with a single line strand and one DNA molecule (if that's what you are looking for).
They are both known to be heavy, hydrogen is one of the two stable isotopes of deuterium
So that it can sustain different life that requires different environments. Angler fish, for example, require a dark and cold environment to thrive while tuna require a light and warm environment.
