Most soil forms in layers. The layers are horizontal, so soil scientists call them horizons. Which of the following sequences accurately explains the formation of the soil. A. Topsoil →Horizon C, which is made of weathered rocks →bedrock that has little or no weathered rock → Horizon E, which experiences leaching.

B. Topsoil →Horizon B, which is made of weathered rocks → Horizon C, which is bedrock that has little or no weathered rock → Horizon E, which experiences leaching.

C. Horizon A which contains topsoil → Horizon E, which experience leaching → Horizon B → Horizon C, which is made or weathered rocks → Bedrock that has little or no weathered rock.

D. Horizon A which contains topsoil → Horizon B, which experience leaching → Horizon B → Horizon E, which is made or weathered rocks → Bedrock that has little or no weathered rock.

Match the descriptions / definitions with the term they best describe 1. three dimensional relationship of the different polypeptide chains in a multisubunit protein or protein complex 2. common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen-bonding between polypeptide backbone atoms. 3. the amino acid sequence of a protein 4. a region on the surface of a protein that can interact with another molecule through noncovalent bonding. 5. three-dimensional arrangement of alpha-helices and beta-sheets within a single polypeptide, typically stabilized by a variety of noncovalent bonds, including ionic and hydrogen bonds, and nonpolar interactions / hydrophobic force. 6. the chain of repeating carbon and nitrogen atoms, linked by peptide bonds, in a protein. 7. common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone. 8. portion of a polypeptide chain that has a discrete tertiary structure of its own and can often fold independently of the rest of the chain 9. regular local folding patterns in a protein, including alpha-helix and beta-sheet a. primary structure b. beta-sheet c. protein d. coiled-coil e. polypeptide backbone f. secondary structure g. side chain h. tertiary structure i. binding site j. alpha-helix k. quaternary structure l. protein domain
