  1. a two types, DNA and RNA. DNA forms our genes, RNA reads the genes and helps make proteins, __________ _____ are composed of joined monomers called nucleotides. These nucleotides are composed of a sugar - deoxyribose (DNA) or ribose (RNA), a nitrogenous base (adenine, thymine, cytosine, guanine, or uracil), and a phosphate group
  2. b are parts of a molecule that participate in a chemical reaction
  3. c larger vesicles, membranous sacs that help in digestion, storage, or water removal
  4. d Protons, Neutrons, electrons (subatomic particles).
  5. e some molecules have charged areas - this makes them polar. Polar areas of molecules can bond with polar areas of other molecules to form weak bonds called hydrogen bonds, hydrogen bonds make water cohesive
