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.

Traits that are sex-linked are carried on either the X or Y chromosome. If they are carried by a female, they are X-linked traits, and if they are carried by a male, they are Y-linked traits.
        
             
        
        
        
As the fertility rate increases, the population will increase. That will probably also have an effect on the region by increasing food security. Hope this helps! So it is as population increases, it also increases food security. Have a BLESSED day! :-) :-)
