In the quaternary structure of a protein the polypeptide is folded through the mechanism of amino acids rotating around bonds and folding into a alpha-helix or beta-pleated sheet structure and stabilized by bonds. amino are the building blocks of proteins. They are made up of a center carbon atom bound to a positively charged group and a negatively charged group and a side chain. In the secondary structure of a protein the amino acid side chains of the folded polypeptide interact, forming a complex three-dimensional shape. primary structure formed by amino reactions link amino acids together, forming a linear chain. The of a protein exists if multiple polypeptides bind together to form a functional protein.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
