• B1.1.1

  Chemical properties of a carbon atom allowing for the formation of diverse compounds upon which life is based

• 
  

  Students should understand the nature of a covalent bond. Students should also understand that a carbon atom can form up to four single bonds or a combination of single and double bonds with other carbon atoms or atoms of other non-metallic elements. Include among the diversity of carbon compounds examples of molecules with branched or unbranched chains and single or multiple rings.
  NOS: Students should understand that scientific conventions are based on international agreement (SI metric unit prefixes “kilo”, “centi”, “milli”, “micro” and “nano”).
  

• B1.1.2

  Production of macromolecules by condensation reactions that link monomers to form a polymer

• 
  

  Students should be familiar with examples of polysaccharides, polypeptides and nucleic acids.

• B1.1.3

  Digestion of polymers into monomers by hydrolysis reactions

• 
  

  Water molecules are split to provide the -H and -OH groups that are incorporated to produce monomers, hence the name of this type of reaction.
