1. Name the Organic Molecule
After the picture, state which organic molecule it is and how you know.

2. This is a nucleotide, a monomer of nucleic acids

3. This is a monosaccharide, as seen by the 6 C :12 H : 6 O ratio, the hydroxyl group, and the carbonyl group. This makes a carbohydrate.

4. This is an amino acid, the monomer for proteins
This is an amino acid, the monomer for proteins. Note the Amine group, the Carboxyl group, and the variable R group

5. This is a monosaccharide, as seen by the 6 C :12 H : 6 O ratio, the hydroxyl group, and the carbonyl group. This makes a carbohydrate.

6. This is a nucleotide, a monomer of nucleic acids

7. This is a disaccharide (carbohydrate), since there are 2 monosaccharides bonded.

8. This is a phospholipid, one of the lipid polymers
This is a phospholipid, one of the lipid polymers. Note the structure: 1 glycerol attached to 2 fatty acids and 1 phosphate group

9. This is a triglyceride, another lipid polymer
This is a triglyceride, another lipid polymer. Note the structure: 1 glycerol bounded to 3 fatty acids.

10. This is an amino acid, the monomer for proteins
This is an amino acid, the monomer for proteins. Note the Amine group, the Carboxyl group, and the variable R group

11. This is a nucleotide, a monomer of nucleic acids

12. This is showing the formation of a peptide bond between two amino acids through dehydration synthesis. Note that the Carboxyl group of one amino acid combines with the Amino group of a second amino acid, along with the formation (and release) of water.

13. This is a monosaccharide, as seen by the 6 C :12 H : 6 O ratio, the hydroxyl group, and the hexagonal ring shape. This makes a carbohydrate.

14. Here we see two types of fatty acids, one of the monomers of lipids
Here we see two types of fatty acids, one of the monomers of lipids. This is a fatty acid, since we see a Carboxyl head and a long hydrocarbon tail. The top FA is a saturated FA, as there are no double bonds between carbons in the hydrocarbon tail. The bottom FA is an unsaturated FA, as there is a double bond between two carbons in the hydrocarbon tail.

15. Name that Science Term
After the definition, description or picture, name the science term.

16. This is a covalent bond. We know this since both girls need a blanket and so decide to share it.

17. This is an ionic bond. Note that the Sodium atom gives away one of its electrons to become a Na+ ion, while the Cl atom accepts 1 electron to become a Cl- ion

18. This is a triple covalent bond
This is a triple covalent bond. Each nitrogen shares 3 electrons with the other Nitrogen, for a total of 6 shared electrons

19. This is a polar covalent bond (or polar water molecule)
This is a polar covalent bond (or polar water molecule). Note the partial negative charge on Oxygen and the partial positive charges on each hydrogen.

20. The green dashes show Hydrogen bonds: notice the attraction between the white Hydrogen and the red Oxygen

21. This is homeostasis, one of the characteristics of life
This is homeostasis, one of the characteristics of life. In response to feeling hot, the man is sweating.

22. This is growth & development, another characteristic of life
This is growth & development, another characteristic of life. Throughout its life, a frog develops from a single cell to a tadpole.

23. This is evolution, another characteristic of life.

24. This is a solution, note that it is composed of a solute in a solvent.
