The correct answer is: A.Prokaryotes have no nucleus and fewer genes.

Here's why:

The hypothesis that prokaryotes evolved before eukaryotes is supported by certain characteristics of prokaryotic cells that are simpler and more primitive compared to eukaryotic cells. Specifically:

Prokaryotes have no nucleus and fewer genes: Prokaryotes, such as bacteria and archaea, lack a membrane-bound nucleus and typically have a single, circular DNA molecule. They also have fewer genes compared to eukaryotes.

These simpler characteristics are considered more primitive, suggesting that prokaryotes likely evolved before eukaryotes, which have a more complex structure, including a membrane-bound nucleus, multiple linear chromosomes, and more genes.

Now, let's look at why the other options are incorrect:

B.This is false. Prokaryotes are generally simpler than eukaryotes. T...
