Classifying things by observation can best be done by using a : Taxon
Taxon divided organisms into different groups based on their unique similarities, and these similarities can be recognized by observing parts and behavior of the organisms. For example, Organisms generally divided into two groups. Those who have a backbone (vertebrata, such as mammals and reptiles ) and those who don't have backbones (such as arthropoda)
This is the best way to classifying the organisms because the similarities between them do not exist in their backbones alone. This give more room/possibilities for the classification. For example, The organisms could also be classified by other similarities (such as how they obtain food, their body structure, how they reproduce, etc)
The biggest help for the scientists may be provided by the ground layer in which the bones were found. If the layer of ground is not disturbed, than the scientist can easily see the time periods from the structure and color of the ground, and thus determine the time period from when the fossil originates and the approximate age of it.
Epstein-Barr virus (EBV) is an important human pathogen that establishes a lifelong persistent infection and for which no precise animal model exists.Agents representing EBV and sets of B and T lymphocytes move and interact on a three-dimensional grid approximating Waldeyer’s ring, together with abstract compartments for lymph and blood.
Yes it can be studied by the scientific method because it is testable and observable.
