Question

based on this information, which statement best describes e. coli?
a. e. coli are eukaryotic, multi - celled organisms because they are highly complex and can perform many functions.
b. e. coli are prokaryotic, multi - celled organisms because they are highly complex and can change to be damaging or beneficial.
c. e. coli are prokaryotic, single - celled organisms because prokaryotic cells can replicate very fast.
d. e. coli are eukaryotic, single - celled organisms because eukaryotic cells can replicate very fast.
e. coli are typically found in the intestines of humans and animals.
they are normally harmless, but some types of e. coli can cause illness. e. coli are known for the ability to rapidly undergo cellular reproduction, causing illness quickly.

Explanation:

E. coli is a bacterium. Bacteria are prokaryotic (lacking a nucleus and membrane - bound organelles) and single - celled. The passage mentions that E. coli can rapidly undergo cellular reproduction. Prokaryotic cells, like those of E. coli, can replicate quickly. Eukaryotic cells (options A and D) have a more complex cell structure with a nucleus and organelles and are not characteristic of E. coli. Option B is incorrect as E. coli is single - celled. Option C correctly identifies E. coli as prokaryotic and single - celled, which aligns with the fact that prokaryotic cells can replicate fast.

Answer:

C. E. coli are prokaryotic, single - celled organisms because prokaryotic cells can replicate very fast.
