By the way, I LOVE BIOLOGY!
the characteristics of prokaryotes are:
- Lack an organised nucleus and other membrane organelles
- Found in a central part of the cell which is known as the Nucleoid
- The cell wall of the prokaryotic cell acts as an extra layer of protection as it can help maintain dehydration and the cell shape

Answer:
Natural selection
Explanation:
Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.
This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
