Explanation:
It was Carl Woese who divided the prokaryotes into 2 kingdoms, Eubacteria and Archaebacteria based on RNA studies. So. this led to additional 6th classification added to Whittaker's classification of 5 kingdoms.

Purebred can be described as organisms that result from true-breeding. True breeding occurs parents who have a homozygous genotype are crossed so that the offspring produced might be similar to them.

However, the phenomenon of pure breeding limits the gene pool and genetic variety becomes limited by such methods.
Binary fission is for reproduction of a cell by division into two equals parts
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey
