It is a basin
Explanation:
The Midwestern region is made up of sedimentary rocks because it is a basin. In a basin, sediments accumulates and they form sedimentary rocks there.
- Sedimentary rocks are rocks that are laid down in natural depression on the earth surface.
- These depressions serves as the collection point of sediments from different sources.
- When wind, water glaciers brings materials here, they settle and accumulate.
- Compaction, cementation and lithification of sediments occur here and sediments are transformed into sedimentary rocks.
Therefore, the Midwestern region must have been a basin for sedimentary rocks to have formed there.

Answer:
Epigenetics.
Explanation:
Epigenetics is the study of phenotypic changes which are heritable but not related to changes in the DNA sequence. It is influenced by several factors including the environment.
An example of epigenetics is DNA methylation: addition of methyl group to some part of the DNA that prevents that part from being expressed. Other examples include history modifications.
In summary, Epigenetics describes inheritance through other mechanisms than through the DNA sequence.
