The layer below is called the subsoil, which is mainly composed of clay and sand. Below it is a frayed rock layer. And deep down is a solid rock layer called the bedrock.
Bedrock is the type of rock on which the soil rests. Through erosion and a weathering process, the parent rock enables the inorganic sector of the land to develop.

Answer:
The correct answer is ''All of these are circumstances in which a DNA microarray would be useful.''
Explanation:
A DNA microarray is used to determine the complete genetic expression of a tissue at a given time. DNA microarrays is one of the most important applications for the information obtained from the systematic sequencing of complete genomes. They consist of a membrane, which can be made of nylon, silicone or a simple glass slide. The DNA of many genes, arranged according to a specific pattern, is immobilized on this membrane. These DNA fragments, which are known as probes or oligos, are arranged in microscopic spots. Microarray technologies are used in research at the molecular level, they allow the study of simple changes in the DNA sequence and mutations in complex genes that are associated with a specific disease, helping to diagnose diseases.
