I’m confused on ur multiple choose “answers”
An herbivore is an organism that only eats plants, a carnivore is an organism that only eats meat, an omnivore is an organism that eats both plants and meat, a decomposer (fungi and bacteria) break down dead matter and feed off of that, I don’t know the rest
A unicellular protist is a eukaryotic cell because it has a nucleus enclosed by a membrane. Protist cannont be grouped with plants, animals or fungi. However they are still eukaryotic.
That would be the nuclear membrane. Eukaryotic cells have a nucleus that encases their DNA, so it stays safer than it would in a prokaryotic cell.
