Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.

Answer:

The virus that generates chickenpox disease is a virus of the family called "herpes" where once they infect the human organism they are not eliminated by human defense, but are reserved and coexist in the organism in the lymph nodes, and when faced with immunodeficiency situations for certain reasons, it generates their reactivation, manifesting a recurrence of the disease.

Explanation:

The chickenpox virus is called the Zoster chickenpox virus, once it infects the human in his childhood, it settles in the ganglion near where it is inactively inoculated.

This is reactivated again manifesting shingles or herpes zoster in adulthood and in situations of immunodeficiency as in those malnourished humans, or who are exposed to long hours in the sun, or who suffer stressful situations.

Shingles is a disease that manifests itself in a very painful way (more than chickenpox) in the form of scabs and vesicles in different possible areas.
