cytoplasm, cell wall, and dna
dna, cytoplasm, and nucleus
cytoplasm, dna, and ribosomes
nucleus, ribosomes, and dna
which of the following statements is true? it might help to remember that you are a eukaryotic organism.
prokaryotic organisms are always unicellular
prokaryotic organisms can be either unicellular or multicellular
eukaryotic organisms are neither unicellular nor multicellular
eukaryotic organisms are always unicellular

Explanation:

1. All cells have a cell - membrane, cytoplasm (the jelly - like substance inside the cell), DNA (the genetic material), and ribosomes (for protein synthesis). Not all cells have a cell wall (animal cells don't) and not all have a nucleus (prokaryotes lack a nucleus).
2. Prokaryotic organisms are always unicellular. Eukaryotic organisms can be unicellular (e.g., yeast) or multicellular (e.g., humans).

Answer:

1. Cytoplasm, DNA, and ribosomes
2. Prokaryotic organisms are always unicellular
