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.
Poor sanitation allows rodents to settle in
Improper storage of foods encourages them to stay
Removal of the rodents' predators, such as snakes, also allows population to rise
