Answer #1

Answer:- The two primary constituent molecules of peptidoglycan chains are N-acetylglucosamine acid (GlcNAc or NAGA) and N-acetylmuramic acid (MurNAc or NAMA) which are covalently bound to each other in alternating fashion.

Peptidoglycan or murein is a polymer consisting of sugars and amino acids that construct a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component has alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM).

Rayon and cotton swabs are both composed of cellulose. Rayon fibers have shorter cellulose chains. Which is more polar? Since the molecules in cotton consist of longer cellulose chains than those in rayon cellulose, the longer cotton molecules are also packed more in-line (crystalline areas) with each other than rayon’s more random (amorphous areas) molecules

Consider two different separated spheres in otherwise empty space that are bound to each other in a steady state by only gravity (they aren’t in contact, and no other forces are acting on either one of them). In order to maintain a steady state, they must be orbiting around each other. In this situation the center of mass must move with constant velocity; assume it is at rest. The two could follow elliptical paths, however assume the paths are both...

The two largest diner chains in Kansas compete for weekday breakfast customers. The two chains, Golden Inn and Village Diner, each offer weekday breakfast customers a "breakfast club" membership that entitles customers to a breakfast buffet between 6:00 A.M. and 8:30 A.M. Club memberships are sold as "passes" good for 20 weekday breakfast visits. Golden Inn offers a modest but tasty buffet, while Village Diner provides a wider variety of breakfast items that are also said to be quite tasty....
