What can be inferred from this excerpt is : ( D ) Individuals with favorable variations survive and reproduce.
<h3>Effects of genetic variations in species</h3>
When the insecticide was sprayed some of the cockroaches survived and continued reproduction due to their resistance to the spray.Therefore it can inferred that although the cockroaches share the same genetic materials, the variations in individuals within the same specie played a role in the survival of some of the cockroaches.
Hence we can conclude Individuals with favorable variations survive and reproduce.

Answer:
4. Peptidoglycan
Explanation:
"Most bacteria can be broadly classified as Gram positive or Gram negative.
Gram positive bacteria have cell walls composed of thick layers of peptidoglycan.
Gram positive cells stain purple when subjected to a Gram stain procedure.
Gram negative bacteria have cell walls with a thin layer of peptidoglycan. The cell wall also includes an outer membrane with lipopolysaccharide (LPS) molecules attached."
