Your book research must say something different then the classroom notes unless boxes are merged. Student conclusion may include more then one question and ALL new, major vocabulary should be circled. TopicsQuestionsBook ResearchClassroom NotesStudents conclusions1. Matter1. What is the difference between an atom and an element?2. What are the four elements that make up 96% of living matter?2. Elements properties are based on atomic structure.3. Draw and label the various parts of a carbon atom, including the atomic number atomic mass, valence electrons and dot structure.4. What physical properties give the atom its unique properties?5. What is an isotope and how can they be used in Biology?3. Bonding: Atom to Atom and Molecule to Molecule6. Explain the difference between nonpolar covalent, polar covalent and ionic Bonds 7. Why are both strong covalent bonds and weak attractions between molecules both important in Biology?8. Distinguish between the four weak attractions between molecules.  9. Explain how these attractions can alter the shape of a macro molecule intern effecting its biological function.  10. What is a chemical Equilibrium?  4. Polarity of water.11. What are 5 properties of water that make it so important to life on earth?12. Draw a water molecule and explain why it is polar and where the potential hydrogen bonds could be.  5. Emergent properties of water.13. How does adhesion and cohesion contribute to the movement of water through plants.14. How does water moderate heat? 15. How does water act as an insulator? 16. How is water a solvent? 17. Explain the difference between hydrophobic and hydrophilic and why are these properties responsible for the compartmentalization of cells?6. How does water affect the acidic and basic conditions of various environments?18. What are the products of dissociation of water? 19. Define acids and bases and pH.  20. What is a buffer and why is it so important in Biology?    2 % I J 3 5   &'(˽˨{mfff\h%h%5\ hpp5\hpphc556>*\]hpphc55\ h>hc5 hc55\ h*85\ h!x5\ h^7"5\ h%5\hxO56CJ\]aJh%56CJ\]aJh%5CJ\aJh] 56CJ \]aJ h6356CJ \]aJ h%56CJ \]aJ #2 $$Ifa$gd%gd%$a$gd63 ( kd$$Iflr\b/; S  t200<644 lap2yt!x    $Ifgd% $$Ifa$gdxO   ` 5) $Ifgd% $$Ifa$gdxOkd,$$Ifl4\\/;` `  t00<644 lap(yt!x` a b c ,kd$$Ifl4\\/;     t00<644 lap(yt!x $Ifgd%c  ! $Ifgd% $$Ifa$gdxO!
