Document Summary
In our nucleus, there are 23 pairs of chromosomes (linear) Taxonomy: taxonomy is the branch of biology concerned with naming and classifying the diverse forms of life on our planet, human: homo sapiens (genus; species, red fish: sciaenops ocellatus (genus; species) There are 3 domains of life: bacteria, archaea, eukarya {eukaryote- animals, fungi, plants, protists} Taxonomic categories: the organization of taxonomic grouping arranges organisms in sets. **table of taxonomic categories: human, chimpanzee, wolf, sequoia tree, sunflower** The category genus groups together closely related organisms which may or may not interbreed: b. This separation based on interbreeding defines the category species. (biological. Species is the biological group which includes all the organisms which are (or have the potential for) interbreeding = biological species concept: b. Many species were originally distinguished by morphology; if two organisms look alike, they must be the same species: c. however, biological species are based on the ability to reproduce in nature.
