Question

characteristics

• single - celled
• has ribosomes
• dna found in nucleoid
• found living in pond water
• lacks membrane - bound organelles
• has cell wall

based on these characteristics, the student claims that the organism must be prokaryotic. which two characteristics can be used to defend their claim?
a single - celled
b has ribosomes
c dna found in nucleoid
d found living in pond water

Explanation:

Prokaryotes have DNA in a nucleoid region instead of a membrane - bound nucleus and lack membrane - bound organelles. These are key defining features of prokaryotes. Single - celled can apply to eukaryotes too (like yeast), having ribosomes is common to both prokaryotes and eukaryotes, and living in pond water is not a defining characteristic of prokaryotes.

Answer:

C. DNA found in nucleoid, Lacks membrane - bound organelles (not listed as an option but the key ones; if choosing from given options, C is the most relevant as it is a unique prokaryotic feature among the choices)
