BIOL 1201 : Bio Exam 1 Study Guide
Document Summary
Barophile: bacteria: halophile bacteria that live in osmotic equilibrium with 3 molar urea. Love salt: thermophile love the heat , exists at temperature up to 132 degrees. Endotherms: penguins, polar bear, humans, tiger, tuna | ectotherms: fish, reptiles, amphibians. Number of protons and neutrons in the nucleus. 2 max in the first shell and 8 max in the second and third shell. Number of electrons needed to fill the outermost shell of an atom. Know how to calculate this for atoms important in biological systems. Valence: number of electrons needed to fill the outermost shell of an atom and valence electrons: the electrons contained in the outermost electron shell of an atom. Know how to calculate the mass of a molecule. Strong bonds: covalent bonds (polar and nonpolar) form when pairs of electrons are shared. Surface tension- spiders on water: ionization - dissociation into acid(hydronium ion) and base (hydroxyl ion)
