Animal viruses cannot replicate in:

Explanation

One of the most important features of viruses is that they can reproduce unity in living cells, where they reproduce by replication. Viruses cannot replicate in blood plasma. Blood plasma is the liquid part of blood that does not contain cells. It is made up of water, proteins, sugars, and other nutrients. Viruses need a host cell in order to replicate, and they cannot do so in blood plasma. Also Viruses cannot replicate in skin cells. Skin cells do not have the machinery that viruses need to replicate, such as the ribosomes that are needed to make proteins. Additionally, the skin is covered in a layer of dead cells that acts as a barrier to viruses. Viruses cannot replicate in plant cells. Viruses need to hijack the host cell's machinery in order to replicate, and plant cells have different machinery than animal cells. This is why plant viruses have evolved to specifically infect plant cells.
