Which viruse reproduces & what reproductive cell ?
Thepotemich [5.8K]
<span>Viral reproduction is termed viral replication. Viral replication is the term used by virologists to describe the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. From the perspective of the virus, the purpose of viral replication is to allow production and survival of its kind. By generating abundant copies of its genome and packaging these copies into viruses, the virus is able to continue infecting new hosts. Replication between viruses is greatly varied and depends on the type of genes involved. After replication of the virus has occurred, the virus will generally exhaust all the cellular resources, leading to cell death and the next step of the viral life cycle: viral shedding. However, a virus may choose, depending on the virus and environment, to instead become dormant within the cell, to emerge later. This would be deemed viral latency.</span>

The correct way to calculate population size is by dividing the total population by the land area.
Iteru [2.4K]
I think this is false because using this formula, you find population DENSITY, not size.
