Answer:
Abiotic factors can be described as the non-living components of a biome. Abiotic factors that help to characterize a biome include:
Climate: The climate of a place will determine which species will be able to live in that area.
Temperature: Temperature changes in an area will lead to the changes in the changes in the biotic factors. For example, certain species will migrate due to temperature changes.
Soil type: The soil type of a place will determine the type and number of plants or trees which will be able to grow on the area.
Amount of sunlight: Sunlight is an important abiotic factor for species of an area.
Amount of water: The amount of water is a necessary abiotic factor as all species require water.

Correct Answer:
(C) the pipe passed through a diamond-stability field and thus may contain diamonds
Explanation:
The passage from which the question was gotten is attached below:
<u>Diamonds are almost impossible to detect directly</u>
<u></u>
Diamonds are almost impossible to detect directly because they are so rare: very rich kimberlite Line pipes, the routes through which diamonds rise, may contain only three carats of diamonds per ton of kimberlite. Kimberlite begins as magma in Earth's mantle (the layer between the crust and the core).
As the magma smashes through layers of rock, it rips out debris, creating a mix of liquid and solid material. Some of the solid material it brings up may come from a so-called diamond-stability field, where conditions of pressure and temperature are conducive to the formation of diamonds.
If diamonds are to survive, though, they must shoot toward Earth's surface quickly. Otherwise, they revert to graphite or burn. Explorers seeking diamonds look for specks of indicator minerals.
Answer:
Middle class
Explanation:
About 70% of all Americans consider themselves middle class. In reality however, the number is down to 50% and going down farther every year.
The belonging to middle class is measured based on income level, there are, however, many different factors that determine it farther: the level of education, access to private healthcare, employment situation, living in a specific neighborhood, cultural activities.
Middle class is slowly disappearing as the wage gap between high and low earners is getting wider. The are far more poor people than before, while the richness is in the hands of few only: big cooperations or business tycoons. Therefore, if the trends continues, there would be lower and upper class only.
