Relative humidity indicates how moist the air is. Relative humidity is also approximately the ratio of the actual to the saturation vapor pressure. Actual vapor pressure is a measurement of the amount of water vapor in a volume of air and increases as the amount of water vapor increases.
Inbreeding: inbreeding brings out more recessive alleles in a population, as they are more exposed and then eventually become more common.
Isolation: if a group of a species becomes isolated from another group of the species, these individuals mate with eachother and as the population of the isolated species grows, the recessive alleles will show.
Produce nutrients and food, to convert light energy to chemical energy through the process call photosynthesis.
This would be bacteria ; aka a prokaryotic cell
