If a report on the galapagos islands has a section that says "species of the islands" do you guys think i have to list every species on the islands or would you say that i just pick a few? ?

I think it would depend how many species are on the island. If there are a lot of species a would only list the major ones but if there aren't that many I would list them all.

It's probably because some types of violets are blue

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
