Since prokaryotic cells _______________________, they have the ability to adapt faster to changing environmental conditions than
I am Lyosha [343]

Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

<h3>What are prokaryotic cells?</h3>

Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.

On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.

Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.

Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.
