Explanation:
Acute necrotizing ulcerative gingivitis (ANUG) occurs due to poor oral hygiene which encourages plaque to form on teeth, causing inflammation of the surrounding gum tissues. The microorganisms that are known to inhabit the damaged tissues are oral spirochaete which includes Borrelia,Fusobacteria, Bacteroidese and Peptostreptococcus. Streptococcus is not an oral spirochaete therefore is excluded. I hope this helps.
<span>Research partitioning is an adaptive evolution that when
species are have similar preys, they compete with each other and one species is
deemed to extinct in the process however if two species are of different preys,
then they can exist with one another. To exist with one another, organisms
belonging to a same species either compete for the resources or divide it
amongst themselves. This concept is important because it helps in diversified
ecology, where animals and plants of the same species co-exist and creates a
beauty with nature.</span>
