Document Summary
If something contains mitochondria, it is a eukaryote. One group of eukaryotes (protists) can be single celled or multicellular. So you can"t decide whether something is a prokaryote or eukaryote simply. Mitochondria are one of the things that distinguishes prokaryotes from eukaryotes. Prokaryotes are kind of unorganized inside; there is a bunch of dna floating all over the place. Review from last class: testable vs. non-testable questions. You can answer the question simply by looking at the thing you wish to test. You need to be able to come up with an experiment that would answer that question. )f you don"t need an experiment to test it, it is not testable. The goal is to determine the sort of question you can develop an experiment to test, or if you could figure out the answer to your question simply by observation. Change: inherited characteristics of a population that became different.
