Sa researcher in a protein lab, you analyze two different proteins for their shape and the amino acids they contain. your results show that the two proteins have exactly the same numbers and types of amino acids, but they have different shapes. what is the best explanation for these results?

The two proteins may have exactly the same numbers and types of amino acids but the sequence of the amino acids along their polypeptide chain may be different and that is reason enough for them to have different shapes. Amino acids side groups differ in polarity, charges, shape, and size and will determine how the polypeptide folds at local regions within the protein - based on interactions with other local regions within the same chain - or with another chain of a tertiary protein. This is due to the fact that the interactions between amino acid side groups of a polypeptide influence, for example, the number and positions of hydrogen and disulfide bonds within the protein.

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.  

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
