Correct answer: B). Easy to cultivate and fertile
The prairie is grassland soils that possess a dark colored surface and these soil are highly fertile in nature. These soils are rich in minerals like calcium and magnesium.
The dark color of soil comes from the added organic matter to the soil that comes from the roots of prairie plants. They are formed in the areas that are too dry to be forested, but too wet to be desert.

Answer:
A is a eukaryotic cell while B is a prokaryotic cell
Explanation:
The researcher can conclude that cell A is eukaryotic while cell B is prokaryotic.
In eukaryotic cells, the DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.
Prokaryotic cells, however, lack a nucleus. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.
