Using the template below that represents the four levels of protein structure, place an X on each level that is expected to be altered as a result of the amino acid substitutions shown in figure 1

The given question is incomplete as there is no figure attached. However, the correct figure is attached to the

Due to the amino acid substitutions, there will be alteration or modification in all the levels of protein structure, since there is an interchange n between two very crucial residues and two amino acids extremely different in nature.

Amino acid substitution is a change in one or more amino acids to another amino acid that takes place in the primary structure. This results in a change in secondary structure and then further. Thus the X should be placed on all the levels of protein structure.

the answer is d.) homologous; have mammary glands

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
