Biochemistry and Macromolecules Quiz

What is a hydrogen bond?

• An attraction between molecules of the same substance

• A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule

• A substance that is dissolved in a solution

• A solution with a pH less than 7

What is cohesion?

• An attraction between molecules of the same substance

• A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule

• A substance that is dissolved in a solution

• A solution with a pH less than 7

What is adhesion?

• An attraction between molecules of the same substance

• A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule

• A substance that is dissolved in a solution

• An attraction between molecules of different substances

What is a solution?

• An attraction between molecules of the same substance

• A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule

• A homogeneous mixture of two or more substances

• A substance that is dissolved in a solution

What is a solvent?

• An attraction between molecules of the same substance

• A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule

• A substance that is dissolved in a solution

What is a solute?

• An attraction between molecules of the same substance
