Answer: C. The C horizon is very deep.
Horizons are the layers of soil develops as a result of soil formation. Horizon lies parallel to the earth surface. Each horizon differs from the other on the basis of amount or organic matter present, color of the soil, texture of soil and other components making up horizon, and amount and type of minerals present in the soil.
C horizon is the horizon that lies deeper region of the collective soil horizon. It consist of unweathered or partially weathered rocks or their aggregates. Therefore, it retains the original chemical composition of the parent rock. This results in the higher mineral content as compared to other horizons. This horizon also lacks the organic matter as no or very little decomposition activity of plant and animal matter takes place. Therefore, color of soil in this horizon in the absence of organic matter remains light.
Hence, a sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar is because of the fact that the C horizon is very deep.
Answer:
A genetic disorder that is inherited as a recessive trait is sickle cell anemia.
Explanation:
Sickle cell anemia can be described as a disorder which is caused by a mutation in the hemoglobin beta gene which is found on chromosome number 11. The pattern of inheritance of sickle cell anemia is autosomal recessive which means that both the alleles of the gene shall be recessive for the trait to occur. A person with one recessive allele for the trait will not carry the disease but will be a carrier for the disease.
The answer your looking for is the insula. Hope this helps.
You can determine that the igneous intrusion is younger than layer C, because layer C is the oldest, acknowledging the fact that it is the deepest layer.
