question 1 of 10
why are archaea in a different domain from bacteria?
a. they both evolved from eukaryotes.
b. they shared a common ancient ancestor.
c. they developed along different evolutionary paths.
d. they are prokaryotes, but bacteria are eukaryotes.

Explanation:

Archaea and bacteria are both prokaryotes. They are placed in different domains because they evolved along separate evolutionary paths with distinct molecular and cellular - level characteristics. Option A is incorrect as they did not evolve from eukaryotes. Option B only mentions a common ancestor but not the divergence. Option D is wrong since both are prokaryotes.

Answer:

C. They developed along different evolutionary paths.
