The "Spanish" influenza pandemic of 1918–1919, which caused ≈50 million deaths worldwide, remains an ominous warning to public health. Many questions about its origins, its unusual epidemiologic features, and the basis of its pathogenicity remain unanswered. The public health implications of the pandemic therefore remain in doubt even as we now grapple with the feared emergence of a pandemic caused by H5N1 or other virus. However, new information about the 1918 virus is emerging, for example, sequencing of the entire genome from archival autopsy tissues. But, the viral genome alone is unlikely to provide answers to some critical questions. Understanding the 1918 pandemic and its implications for future pandemics requires careful experimentation and in-depth historical analysis.

1) The six kingdoms in the six-kingdom system of classification are Archaebacteria, Eubacteria, Protista, Fungi , Plantae and Animalia
2)The two things that make archaebacteria difficult to study are that archaebacteria lived only in these extreme environments and that we don't know how to feed them for studying them
3) Protista is the most heterogeneous kingdom in terms of morphology
4) The difference between kingdom and domain is that the kingdom is one of the five major groups of living organisms while the domain is one of the three taxonomic categories of living organisms above the kingdom level.
Sorry if i’m late to answer it
I hope it’s correct
A theory which is tested again and again and found to fit the facts and from the valid predictions may be made is then known as scientif ic law or priciples..
