Need help finding the correct answer that I got incorrect. I don't understand the questions that are marked wrong since I got them incorrect.

Our growing understanding of how proteins fold allows researchers to make predictions about protein structure based on amino acid sequence data. Consider the amino acid sequence. Where might bends or turns occur? Where might intrachain disulfide cross-linkages form? residues 7 and 19 between residues 12 and 22 residues 10 and 11 between residues 4 and 18 residues 14 and 16 between residues 13 and 24 residues 9 and 19 between residues 14 and 16 Suppose that the sequence is part of a larger globular protein. Consider the probable location, either on the external surface or the interior of the protein, of each of the amino Which statements correctly describe the probable acid residues. locations of the amino acids? The table gives the hydropathy index values for selected Asp is located on the external surface of the protein because it is charged. amino acids in the peptide. Ile and Lys are located in the interior of the protein because they are not polar. Ala is located on the external surface of the protein because it is polar. Thr is polar and can be located on the external surface or in the interior of the protein. Gln is located in the interior of the protein because it is uncharged.
