BIOL 1201 Lecture : Biology 1201 Fall Week 1 Lecture Notes
Document Summary
Pre-lecture video-scale of nature: scientific method- used to prove or disprove a theory. What happens as a result of this process: terminology, hypothesis-prediction of something that hasn"t been tested yet, theory-tested many times and always supported(has validity, law-theory that has continued to be tested and continued to gain support. What is life: characterizations of living systems, organization (how its arranged, energy use (all organisms exchange gases, development, reproduction, evolve, respond to the environment. What determines solubility: solubility, like dissolves like, like in terms of polarity, nonpolar solutes dissolve in nonpolar solvents, polar solutes dissolve in polar solvents. 6: atomic mass-sum of protons and neutrons. What determines the polarity of a molecule: the type of bonds within a molecule, the bond determines if its polar or nonpolar. Chemical bonds: form when atoms gain or lose electrons or share electrons, they are the result of electrical attractions between atoms.
