Answer:
FSH, LH, and TSH all have a similar structure and are found in vertebrates and invertebrates alike. Therefore, they can be defined as HOMOLOGOUS
Explanation:
FSH, LH, and TSH are homologous because of similarities in their structure which are found across both vertebrate and invertebrate

Answer:
d) short amino acid chains, NAG, NAM, and some lipid proteins
Explanation:
Bacterial cell walls are made up of a rigid layer that is responsible for the resistance of the cell wall. This layer is called Peptidoglycan.
The basic structure of peptidoglycan is:
- A long chain of sugar derivatives, <u>N-acetylglucosamine (NAG) </u>and <u>N-acetylmuramic acid (NAM)</u>. These two sugars are linked together by glycosidic bonds. Although these links are strong and make up the structural backbone, they are not sufficient to give the wall rigidity.
- The amino acids (<u>L-alanine, D-alanine, D-glutamic, and Lysin</u>) play an important role as peptide bridges that cross-braced the chains, joining the N-acetylmuramic molecules (NAM) together, giving greater rigidity to the structure.
Lipid proteins embedded in the wall with structure functions can also be found in the cell wall.
