Working of a spectrophotometer - In a spectrophotometer, commonly used UV radiation sources are hydrogen and deuterium lamps and for visible radiation, atungstenfilament lamp is used. For IR radiation Nernst Glower is used. A monochromator is used to resolve polychromatic radiation into individual wave...

Cladistics aims to create nested hierarchies of interrelated groups, each of which includes a common ancestor and all of its descendants. Groups that share many unique traits are often nested within the same hierarchy and are considered more closely related than groups that share fewer traits and ...
