1. Oh Christmas tree, You stand there slowly dying. Oh Christmas tree, One spark, you’ll soon be frying. Needles falling on the floor, Soon we’ll throw you out the door. Oh Christmas tree, You stand there slowly dying.

2. Unit 2- Approx 10 % of final Identify and state what three particles make up atoms. Identify the types of charges associated with subatomic particles and describe how these particles interact based on charges. Differentiate between an element and an isotope. Distinguish between a compound, a molecule and an element. Identify and describe the three “types” of chemical bonds. Explain why atoms from bonds. Explain how van der Waals forces aren’t bonds. Define what a valence electron is and discuss why this is important in forming bonds. Describe and explain the trend in the number of bonds an element will make and the group it’s in on the periodic table. Define what is meant by electronegativity.

3. Unit 2 Chemical reactions (P-syn and Cellular Resp) Differentiate between monomers and polymers in molecules Identify the properties of and distinguish monosaccharides, polysaccharides, lipids and other organic compounds

4. Unit 3 ~ 10% Define and identify what a mixture is and provide examples of a mixture. Distinguish between a solution, suspension, solute and solvent Define what is meant by an acid and a base. Distinguish between acids and bases on a pH scale. Explain how acids and bases dissociate and describe why pure water has a pH of 7. Summarize why water is polar and explain properties of water based on polarity.

5. Identify the four macromolecules in living organisms and explain their roles in living organisms. Describe/identify the partial charges on the four macromolecules. Identify the monomers that make up three of the body’s main macromolecules and describe/identify the partial charges on those molecules. Evaluate/predict how these monomers and polymers will behave in water. Distinguish between monosaccharides, disaccharides and polysaccharides. Distinguish between structural proteins, enzymes and regulatory proteins. Explain the role of enzymes in bodily chemical reactions (activation energy) and discuss enzymes’ environmental sensitivities

6. Unit 4 ~ 13 % Define and discuss the cell theory (three parts). Discuss why cells are the basic unit of life. DISTINGUISH between prokaryotes and eukaryotes. Identify and discuss the role of: cytoplasm, nucleus, vacuoles, vesicles, lysosomes, microfilaments, microtubules, ribosomes, ER (rough and smooth), Golgi apparatus, chloroplasts, mitochondria, cell walls, cell membranes. Identify and discuss what the cytoskeleton is mostly composed of. Describe and summarize how proteins are assembled and “shuttled”

7. Formulate three predictions about chloroplasts and mitochondria if the endosymbiont theory is true. Identify the components of the lipid bilayer and explain the role of those components in limiting how/what substances can cross a membrane. Include hydrophobic and hydrophilic in your explanation. Compare and contrast cell walls in prokaryotes and eukaryotes. Explain why the lipid bilayer could not be reversed in structure.

8. Homework You may use a ‘cheat sheet’ for the test. Maximum 8.5x11 inches (standard notebook paper) SINGLE SIDED!!!! YOUR writing NO photocopies, reproduction, etc… Your notes on paper I have final say as to whether you can use it.
