Explanation / Answer

11. A disease is the actual tissue damage or product of infection by a particular pathogen.

12. Tissues of the skin are held together in part by hyaluronic acid.In order to facilitate virulence, some pathogens produce the enzyme hyaluronidase that breaks down the hyaluronic acid holding the cells together so that they can invade deeper tissues.

13. A virulence factor is a gene that codes for spmething that makes an organism pathogenic, such as an adhesin or toxin,usually these genes are from an exogenous source, the genes have a different %GC content.The region of the genome where the gene reside is known as Pathogenicity Island.
