Document Summary

Ex: paleontologists infer the functions of different features found in dinosaur fossils. In order for something to function well, it has to have certain features. The properties of a thing depend on what is made of. Properties of individual parts do not predict properties of a thing. As you increase level of organization new properties appear. Dna based chromosomes carries our genetic information. Prokaryotes very small, little cellular diversity to our eyes, a lot of biomechanical diversity. Set of internal membranes that are all connected and related. Hypothesis: organelles evolved from captured bacteria living symbiotically. The molecules of life: the chemistry of life in water. A substance that cannot be broken down to other substances by chemical reactions. Chemical reactions and structures are determined by characteristics of atoms. In a normal atom, # electrons = # protons. The behavior and distribution of electrons in atoms is the basis for chemistry.
