<span>Herpesviridae is a large family of DNA viruses that cause diseases in animals, including humans.
When a person infected once, his immune system develops antidot against the virus, so he becomes immune for that virus for rest of his life. In other words, he can't be affected from that virus again

Answer and explanation:
One of the unordered forms of the dying cell is necrosis.
Necrosis is caused by lesions that impede internal balance control: water and some ions, especially sodium and calcium, normally pumped out, flow freely into the swelling and rupturing cell. The necrosis rupture releases into the surrounding tissue cellular content, rich in proteases, enzymes that "cut" other proteins, and other toxic substances. In addition to direct toxicity to neighboring cells, the stroke generates substances that attract immune cells, causing an intense inflammatory reaction: some types of white blood cells, especially neutrophils and macrophages, converge to necrosis tissue and ingest dead cells. Inflammation, typical of necrosis, is important for limiting infections and removing cell debris, but white blood cell activity and secretions can also damage neighboring, sometimes devastating, normal tissues.
A control is the normal behavior you are testing the variable against. There are two types of variables. The independent variable is what you change to test what the dependent variable is, which is the variable that changes due to the independent variable, and what you generally record your data over.
<span>The role that Stratigraphic dating have played in determining the occurrence of mass extinctions is in its ability to identify different sediment debris. This includes rock and other materials that form or accumulate as the result of natural processes, human activity, or both</span>
