Forensic scientists are able to use ink chromatography to solve crimes by matching documents or stains found at a crime scene to the marker or pen that belongs to a suspect. Forensic scientists analyze the unknown ink and compare it to writing utensils collected from possible suspects.
Symptoms of Variegate Porphyria The hepatic porphyrias primarily affect the nervous system, resulting in abdominal pain, vomiting, acute neuropathy, seizures, and mental disturbances, including hallucinations, depression, anxiety, and paranoia.
In nature these forms usually die out, being weaker growers because of the lack of chlorophyll, which plants use to make the food they need for growth. Variegation can also be the result of a viral infection, showing as discolored veins or leaf areas. This form of variegation is relatively rare, but it is stable. Lonicera japonica âAureoreticulataâ has this type of variegation, with golden yellow veins netting the leaves. Pictured: Lungworts (Pulmonaria) are plants more admired for their variegated foliage than for their flowers. This is Pulmonaria âSpilled Milkâ.
