Question

students are comparing two organisms in the table below. organism 1: has ribosomes, has a membrane - bound nucleus, multicellular, non - complex structure. organism 2: has circular dna, single - celled, no nucleus, has ribosomes. one student concludes that organism 1 must be eukaryotic because it has ribosomes. which statement about this conclusion is true? a. the student is completely correct because only eukaryotic organisms have cells with ribosomes. b. the student is completely incorrect because only prokaryotic organisms have cells with ribosomes. c. the student is correct that it is eukaryotic, but incorrect about only eukaryotes having ribosomes. d. the student is incorrect that it is eukaryotic, but correct about only eukaryotes having ribosomes. part b which two statements support the answer to part a? a. all organisms have cells with circular dna. b. all organisms have ribosomes. c. only eukaryotic cells have ribosomes. d. only eukaryotic cells have a membrane - bound nucleus. e. all organisms are single - celled. f. only prokaryotic cells have ribosomes.

Explanation:

Organism 1 has a membrane - bound nucleus, which is a characteristic of eukaryotic cells. All eukaryotic cells have a membrane - bound nucleus. Prokaryotic cells do not have a membrane - bound nucleus. Organism 2 is single - celled with circular DNA and no nucleus, which are prokaryotic features. Ribosomes are present in both prokaryotic and eukaryotic cells.

Answer:

C. Only eukaryotic cells have a membrane - bound nucleus.
