Macromolecules in Organisms (CLASS ACTIVIТY) Most common elements in living things are carbon, hydrogen, nitrogen, and oxygen. These four elements constitute about 95% ofyour body weight. АН compounds can Ье classified in two broad categories --- organic and inorganic compounds. Organic compounds are made primarily of carbon. Carbon has four outer electrons and can form four bonds. Carbon can form single bonds with another atom and also bond to other carbon molecules forming douЬle, triple, or quadruple bonds. Organic compounds also contain hydrogen. Since hydrogen has only one electron, it can form only single bonds. Each small organic molecule can Ье а unit of а large organic molecule called а macromolecule. There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (СНО). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON PJ.

Then Color code the squirrel with the correct proportion of each element's color. Now color code the carrot with the same colors as you used on the squirrel. 18.5% Ыасk -� [}{] 9.5% yellow ([J �1.0% pink 65% red 0.3% green 3.3% Ыце � � � 0.4% brown 1 (Cc[) p ��i Questions: (1)_ 2.
