In the wild, the only tiger subspecies in the wild that have been observed to carry the white color is the Bengal tiger. Even all the white tigers that have been held captive are partly Bengal in subspecies. It is believed that the rare recessive gene that carries the white color comes from Bengal tigers only.
It is difficult to classify viruses as living organisms because they are not made of cells. They only become alive when they find a host i.e. a living cell to live in.ome algae are difficult to classify because they sometimes do not properly fit in one of the kingdoms since they may have characteristics from a few of the kingdoms.
Virus classification is the process of naming viruses and placing them into a taxonomic system. Similar to the classification systems used for cellular organisms, virus classification is the subject of ongoing debate and proposals.This is mainly due to the pseudo-living nature of viruses, which is to say they are non-living particles with some chemical characteristics similar to those of life.imilar to the classification systems used for cellular organisms, virus classification is the subject of ongoing debate and proposals.
