Answer:
Answered below
Explanation:
Pepetidoglycans are the structural polymers which make up the cell walls of most bacteria.
It consists of the macromolecule, glycan chains, which are repeating N-acetylmuramic acid and N-acetylglucosamine residues. These glycan chains combine or cross-link with peptide side chains (proteins) to form a mesh-like layer outside the plasma membrane of most bacteria.
Peptidoglycan is the major structural component and the basic unit of the bacterial cell wall and provides protection to the cytoplasmic membrane, mechanical rigidity and also regulates the passage of fluid, amino acids, sugar and ions, in and out of the cell.
I think the right answer is B but I don’t know
Must have more protons. Protons are positively charged, so if the atom (or in this case ion) has a net positive charge, it must have more protons (+ charge) than electrons (- charge).
Answer:
42 kg.m/s if the two are moving in the same direction
Explanation:
momentum formula: p=mv
22kg.m/s+20kg.m/s= p
42kg.m/s=p
the momentum of both objects=42 kg.m/s
