The tertiary structure of a protein is a complex arrangement formed as the polypeptide chain folds and twists. the folding and twisting of the polypeptide chain is caused by different interactions between the side chains of the amino acids. the side chains of the amino acids also interact with the surrounding aqueous environment. identify the different types of attractive forces or interactions present in the given tertiary structure of a protein molecule.

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
