The answer is (a.) Mitosis

Ben's cut on his knees will be healed because of mitosis. Mitosis is responsible for the new tissue growth for the healing of Ben's cut. Mitosis is referred as the fundamental process if life. In Mitosis, a single cell will grow and reproduce to two identical cells.

Which of the following environments would not contain fossils

juin [17]

Answer:

as I know

Explanation:

Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.

Peptidoglycan is a polymer of millions of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) sugars based on glucose molec

padilas [110]

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, N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM). 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 (L-alanine, D-alanine, D-glutamic, and Lysin) 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.
