l. macromolecule
m. a large biomolecule that makes up living organisms; may be a protein, a carbohydrate, a lipid, or a nucleic acid

Answer:

To solve this matching problem, we analyze each vocabulary word and its corresponding definition:

1. biomolecule

• Definition: M (a large biomolecule that makes up living organisms; may be a protein, a carbohydrate, a lipid, or a nucleic acid) or J (a carbon - containing molecule that is associated with living organisms but may also be man - made) could be considered. But more precisely, M is a better fit as it directly refers to large biomolecules of living organisms. Wait, no, let's re - check. The definition for biomolecule should be M? Wait, no, let's look again. The option M says "a large biomolecule that makes up living organisms; may be a protein, a carbohydrate, a lipid, or a nucleic acid". But actually, the correct match for biomolecule is M? Wait, no, let's go step by step.

1. biomolecule

• The definition of biomolecule is a large molecule that is part of a living organism (like proteins, nucleic acids, etc.). Option M: "a large biomolecule that makes up living organisms; may be a protein, a carbohydrate, a lipid, or a nucleic acid" matches. But wait, option J: "a carbon - containing molecule that is associated with living organisms but may also be man - made" is about organic molecules? No, biomolecule is a molecule related to biology, so M is for biomolecule? Wait, no, maybe I made a mistake. Let's check each one:

1. biomolecules: M (a large biomolecule that makes up living organisms; may be a protein, a carbohydrate, a lipid, or a nucleic acid)
2. atom: H (the smallest portion of an element found in the periodic chart)
3. covalent bond: C (the type of chemical bond formed when two or more elements share electrons)
4. monomer: A (a small molecule that may be chemically bonded to other like molecules to form a polymer)
5. hydrolysis: E (a chemical reaction that uses water to break apart a polymer into monomers)
6. organic molecule: J (a carbon - containing molecule that is associated with living organisms but may also be man - made)
7. condensation reaction: I (a chemical reaction that combines smaller molecules and forms water as a by - product, often used to form polymers)
8. macromolecule: D (a long chain of monomers)
9. polymerization: L (the process of combining monomers to form a polymer)
10. polymer: B (molecules to form a polymer? Wait, no. Wait, polymer is a long chain of monomers, so D? No, D is "a long chain of monomers" which is macromolecule? Wait, no, let's re - define:

• monomer: A (small molecule, building block)
• polymer: B? No, B says "molecules to form a polymer" – no. Wait, the correct definitions:
• biomolecule: M (large biomolecule of living things)
• atom: H (smallest part of element)
• covalent bond: C (share electrons)
• monomer: A (small molecule, building block)
• hydrolysis: E (uses water to break polymer)
• organic molecule: J (carbon - containing, related to life)
• condensation reaction: I (combines small molecules, makes water)
• macromolecule: D (long chain of monomers)
• polymerization: L (process of making polymer from monomers)
• polymer: B? No, B is "molecules to form a polymer" – no, polymer is a large molecule made of monomers, so D is macromolecule, polymer is B? Wait, no, the option B says "molecules to form a polymer" – that's not right. Wait, maybe I messed up. Let's list all:

Vocabulary | Definition (Option)
--- | ---

1. biomolecule | M (a large biomolecule that makes up living organisms; may be a protein, a carbohydrate, a lipid, or a nucleic acid)
2. atom | H (the smallest portion of an element found in the periodic chart)
3. covalent bond | C (the type of chemical bond formed when two or more elements share electrons)
4. monomer | A (a small molecule that may be chemically bonded to other like molecules to form a polymer)
5. hydrolysis | E (a chemical reaction that uses water to break apart a polymer into monomers)
6. organic molecule | J (a carbon - containing molecule that is associated with living organisms but may also be man - made)
7. condensation reaction | I (a chemical reaction that combines smaller molecules and forms water as a by - product, often used to form polymers)
8. macromolecule | D (a long chain of monomers)
9. polymerization | L (the process of combining monomers to form a polymer)
10. polymer | B (molecules to form a polymer? No, wait, polymer is a large molecule made of monomers, so maybe B is incorrect. Wait, the option B says "molecules to form a polymer" – maybe it's a typo, and it should be "molecule formed from monomers". Assuming that, polymer is B.
11. ionic bond | K (the type of chemical bond formed when two or more elements gain or lose electrons)
12. inorganic molecule | G (a type of molecule that does not include carbon e.g. H₂O, NH₃, NaCl)

Final Matches:

1. biomolecule - M
2. atom - H
3. covalent bond - C
4. monomer - A
5. hydrolysis - E
6. organic molecule - J
7. condensation reaction - I
8. macromolecule - D
9. polymerization - L
10. polymer - B
11. ionic bond - K
12. inorganic molecule - G

(Note: If there was a specific sub - question (e.g., match a particular word), we would focus on that. Since it's a full matching, we provide all correct pairs.)
