Several methods to assess the severity of psoriasis are available including Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA) for psoriasis, and the National Psoriasis Foundation Psoriasis Score (NPF-PS). In terms of body surface area, psoriasis is generally classified as mild when it affects less than 5% of the body, moderate when it affects 5-10%, and severe for >10%. Based on PASI, which includes a rating or score for the surface area of the body affected by psoriasis, the "Area Score" would be 2.

Answer:
It is important to classify the millions of species on Earth because it makes study of organisms easier. Classification occurs on the basis of similarities and differences that is present among the organisms. Organisms are placed in one group if they are similar in characteristics. For example, those organisms which are placed in animals have the ability to move from place to place and unable to make their own food.
