2. Explain Urey and Miller’s experiment: What were they trying to recreate? What was put/added to the flask? Was there oxygen in the flask? Why or why not? What happened/what appeared? Earth 3.6 billion years ago Water = oceans Atmosphere = gasses Electric current = lightning No, oxygen was not in the atmosphere 3.6 billion years ago. The building blocks of proteins, which is a chemical of life.

3. Explain Redi and Pasteur’s experiment Red meat in three jars Open, sealed, and netting Flies/maggots appeared only on the open jar Disproved spontaneous generation – only life comes from life!

21. The more levels of classification organisms share… …the more characteristics they have in common.

22. These kingdoms only have prokaryotes? Archaebacteria & Eubacteria

23. What is the difference between prokaryotes and eukaryotes? Prokaryotes – lack a nucleus Eukaryotes – have a nucleus

24. Taxonomy is…. The scientific study of how living things are classifed

28. Binomial nomenclature is… A naming system in which each organism is given a two-part name.

29. Cladogram Diagram that displays evolutionary relationships among a group of species

30. Spontaneous generation is… The mistaken idea that living things arise from nonliving sources
