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:
Cross-bridges would form in the absence of an action potential from a motor neuron.
Explanation:
The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.
