The body was preserved because the body was frozen in the cold temperature of the Alps shortly after he died and remained frozen until it was found.

<h3>How is a body preserved?</h3>

It is common to observe that bodies are often preserved at a very low temperature hence the body was preserved because the body was frozen in the cold temperature of the Alps shortly after he died and remained frozen until it was found.

The reason why the AIDs virus which contains RNA, to insert into the DNA of a host of T-cells after the AIDs virus enters the cell is because of receptor proteins located on the surface of the virus.

The organism that lacks the ability to maintain their own metabolic pathways and can only reproduce inside of a host cell are the viruses.

The chemicals released by one type of immune cell to directly activate another type of immune cell are the cytokines.
