Cross cultural studies or which can be called ethology is important in studying behavioral biology because ethology is the scientific and objective study of an animal well particularly focuses on its behavioral under natural conditions and viewing behavior as an evolutionary active trait. in some ways we can adopt the learning in this study to what we have.
Answer:
3.14 residues
Explanation:
This kind of sheets has the particularity that the distance between adjacent residues is 3.5 Angstroms. Furthermore, there are two residues per cycle.
Hence, we can calculate easily the number of residues in a segment, by using the expression:
Nr = (256 Å) / (3.5 Å/residue) = 3.14 residues
I hope this is useful for you
