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.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
