Document Summary
The specific heat of water: very high compared to most other molecules, due to the presence of hydrogen bonds extra energy must be put into the system to break these bonds. Hydrogen bonding in ice vs. water: because of the polarity, hydrogen bonds must be a certain distance away from each other, this distance is larger in water than ice, molecules are spaced out further. Carbon: the (cid:862)(cid:271)a(cid:272)k(cid:271)o(cid:374)e(cid:863) of orga(cid:374)i(cid:272) (cid:373)ole(cid:272)ules, due to having only 4 valence electrons very likely to bond/share e- with other. Classes of macromolecules atoms: carbohydrates, proteins, nucleic acids, lipids. Lecture 5: macromolecules of life and the antiquity of life. Lecture 6: radiometric dating and dendochronology; intro to prokaryotic life. Formation and acquisition of carbon-14: neutrons from cosmic rays collide with atmospheric nitrogen, producing carbon-14. Genesis of prokaryotic life: eubacteria, archaebacteria and eukaryotes came together and through a convoluted genetic path formed a common ancestor for all prokaryotic life.
