D. Silicon is the correct answer.
Answer:
migration is a strong force for equalizing the gene frequencies of sub populations in a species. Provided that the migration rate is greater than zero, gene frequencies will eventually equalize.
An example of self-determination is the creation of Czechia and Slovakia.
Explanation:
The self-determination basically means that through the will of the people, a certain goal is a achieved usually(not always though) in peaceful manner, in this case ending a country and creating two new ones. Initially it was one country, Czechoslovakia. This country was composed of two main groups of people, the Czechs and Slovaks, and they peacefully collaborated and coexisted as a unit for several decades.
With the fall of the communism though, it became clear that the Czechs and the Slovaks have different ideals, and that they move into different directions. The people voted in a democratic manner to end the existence of Czechoslovakia, and to form to separate countries roughly divided with a border based on ethnic base. The formation of the new countries happened indeed and it was in totally peaceful manner, with the two countries retaining good relations.
Other examples of self-determination are:
- Creation of Macedonia, Serbia, Croatia, Slovenia, Bosnia out of Yugoslavia
- Creation of Austria and Hungary out of the Austria-Hungary Empire
- Creation of the Baltic states out of the Soviet Union
- Creation of Bulgaria, Greece, Lebanon etc. from the Ottoman Empire

I belive it it O because <span>An O horizon has at least 20% </span>organic matter<span> by mass. Two main scenarios result in the formation of an O horizon: saturated, </span>anaerobic<span> conditions (wetlands) or high production of leaf litter in forested areas. Anaerobic conditions slow the </span>decomposition<span> process and allow organic material to accumulate. An O horizon can have various stages of decomposed organic matter: highly decomposed, sapric; moderately decomposed, hemic; and minimally decomposed, fibric. In a fibric O layer, plant matter is recognizable (e.g., it is possible to identify a leaf). Sapric material is broken down into much finer matter and is unrecognizable as a plant part. Hemic is in between sapric and fibric, with some barely recognizable plant material present. It is possible to have multiple O horizons stacked upon one another exhibiting different decomposition stages. Because of their organic content, these horizons are typically black or dark brown in color. The dominant processes of the O horizon are </span>additions<span> of organic matter, and </span><span>transformations </span><span>from fibric to sapric
