| Genotype | The complete genetic makeup of an individual |
| Haploid | A cell that contains half the total number of chromosomes |
| Heterotroph | An organism that can't produce its own energy, so must consume energy from other sources |
| Heterozygous | Having unmatched alleles for a trait |
| Homeostasis | The ability to stabilize internal conditions when surrounded by changing external condition |

| Population | A group of species that lives in a defined area in a specific time |
| Prediction | A statement that forecasts what will happen based in past facts and evidence |
| Prokaryotic | Describes unicellular organisms that lack a defined nucleus |
