Select the valid comparison between eukaryotes and prokaryotes.
a. eukaryotes are far more metabolically diverse than prokaryotes.
b. prokaryote cells have simpler internal structure and genomic organization than eukaryotic cells.
c. the total biomass of eukaryotes is approximately ten times the total biomass of prokaryotes.

The answer is B.

Explanation:

Prokaryotes are organisms which are unicellular and have no internal membrane-bound organelles nor a nucleus. Instead they tend to have a single chromosome, which is a piece of circular, double-stranded DNA found in the nucleoid of the cell. Whereas eukaryotes are organisms with eukaryotic cells. These are cells that have a nucleus and organelles bounded in a plasma membrane. Examples of these organisms include humans, protozoa, fungi, plants and other animals.
