Explanation / Answer

1. The correct order of taxonomic categories, going from most specific to general is

species->genus->family->order->class->phylum/division->kingdom

Here, the most specific is species and most general is kingdom.

2. Woese- Fox model of classification divided living organisms in three domains also known as Thre domains of life, namely-

Archaea domain, Bacteria domain, and Eukarya domain.
