| Question | Answer |
|---|---|
| endosymbiosis | a mutually benefical relationship in which one organism lives within another. Also, the theory that eukaryotic cells originated through endosymbiotic relationships with ancient prokaryotic cells |
| chemosynthesis | the production of carbohydrates through the use of energy from inorganic molecules instead of light |
| archaea | The Archaea constitute a domain of single-celled microorganisms. These microbes have no cell nucleus or any other membrane-bound organelles within their cells. |
| cyanobacteria | a group of bacteria that can carry out photosynthesis |
| evolution | a heritable change in the characteristics within a population from one generation to the next. also the development of new types of organisms from preexisting organisms over time |
| mutation | a change in the nucleotide base sequence of a gene or DNA molecule |
| homologous structures | anatomical structures that, compared to other anatomical structures in other species, originated from a single anatomical structure in a common ancestor of the two species |
| transitional species | species that are intermediate between those of hypothesized ancestors and later descendant species |
| convergent evolution | the process by which unrelates species become more similar as they adapt to the same kind of environment |
| divergent evolution | the process by which two or more related but reproductively isolated populations become more and more dissimilar |
| species | a group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies |
| embryological development | the embryos of certain species develop almost identically especially in the early stages |
| fossil | the trace or remains of an organism that lived long ago; most commonly preserved in sedimentary rock |
| geology | The science that deals with the earth's physical structure and substance, its history, and the processes that act on it. |
| 14/14 | Your definition of archae would also fit bacteria. They differ based on rRNA differences and the fact that their cell membranes have a different composition that can withstand extreme conditions. |
