Answer:
a. preventing the cross-linkage of NAM subunits
Explanation:
The bacterial cell wall is made of peptidoglycan which is a polymer of alternating N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) residues. The NAM residues are crosslinked to impart additional strength to the cell wall.
Most of the antibiotics that target the cell wall synthesis in bacteria inhibit the enzyme of transpeptidation which in turn cross-links the NAM residues of the polysaccharide chains of the bacterial cell wall. Examples of these antibiotics include penicillins and cephalosporins.
The answer is; saturated soil turns into liquid that can't support buildings
Soil liquefaction occurs mainly in soils saturated, or partially saturated, with water such as in wetlands. During an earthquake, the waves pass through the soil and make it behave like a wave in a fluid. This causes the soil to loosen temporarily and become weak. The foundation of buildings in the soil fail and the structures collapse.
Answer:Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
