    3. Cthe number of protons, neutrons, and electrons
  2. 2What does the atomic number mean?
    1. AThe number of electrons the atom has
    2. BThe number of protons the atom has
    3. Cthe number of neutrons the atom has
  3. 3Which shows correct Lewis dot structure?
    1. AImagen de la opción A
    2. BImagen de la opción B
  4. 4What is the order of chemical bonding from strongest to weakest?
    1. Aionic, van der waals, hydrogen, covalent
    2. Bvan der waals, hydrogen, ionic, covalent
    3. Chydrogen, ionic, van der waals, covalent

  5. 5Water is a [blank_start]polar[blank_end] molecule. When water molecules stick together, it is called [blank_start]cohesion[blank_end]. When water molecules stick to other objects it is called [blank_start]adhesion[blank_end]. Capillary action is when water is soaked up in a plant through [blank_start]adhesion[blank_end] and [blank_start]cohesion[blank_end] working together. (hint for last part: alphabetical order)
    1. Apolar
    2. Bcohesion
    3. Cadhesion
    4. Dadhesion
    5. Ecohesion
  6. 6Hydrophilic means __________________
    Hydrophobic means _______________
    1. Awater "loving" (dissolved in water), "hating" water (repels, wants to get away from water)
    2. B"hating" water (repels, wants to get away from water), water "loving" (dissolved in water)
  7. 7When water molecules at the top of water cohere together to avoid outside molecules, it is called [blank_start]surface tension[blank_end].
    1. Asurface tension
  8. 8What are the four essential organic compounds for life?
    1. ACarbohydrates
    2. BProteins
    3. CNucleic Acids
    4. DWater
    5. ELipids
    6. FAlcohol
  9. 9Carbohydrates create [blank_start]sugars[blank_end] for energy. Lipids store [blank_start]energy[blank_end] with fats. Proteins are important for the [blank_start]structure[blank_end] of cells. Nucleic acids contain the [blank_start]genetic[blank_end] code for cells.
    1. Asugars
    2. Benergy
    3. Cstructure
    4. Dgenetic
  10. 10What is the difference between phospholipids and triglycerides?
    1. APhospolipids have a phosphorus "head" and 2 tails of fatty acids
    2. BTriglycerides have 3 tails of fatty acids
    3. CTriglycerides store fat
    4. DPhospholipids create the cell membrane
    5. EAll of the above
