<span>Early life was too simple to fully fix the sun or use higher functions to provide it's own energy. They were probably more like archaea that are seen around vents in extreme regions, such as the floor of the ocean or in high temperature pools in Yellowstone. These items "eat" the sulfur and other energy to create their needs. This would develop by necessity into mitochondria and chloroplast like bacteria as they ventured out from the vents to other areas and competed for heat and energy</span>
Then cleansing process that removes organic material and reduces the number of microorganisms to a safe level is called Sanitization.
The purification procedure required by public health regulations to get rid of organic matter and bring the number of germs down to a safe level.
For restaurants and other facilities that make food, for instance, there are sanitizing procedures. Depending on your demands, the sanitizing procedure you use will change. You might be using a mop, a chemical, and water to clean a floor. Dishwashers can be used to sterilize the dishes. Or you might be wiping a TV remote with an antibacterial wipe.
Hence, proper sanitization is required during the spread of diseases like COVID 19 and thus, with the help of proper guidelines and sanitization disease spread can be prevented.

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.
