Answer Choice “A.” is the most sequentially correct answer choice from my understanding. Binding must occur before the making of mRNA, so Answer Choices C and D can be eliminated immediately. If the RNA Polymerase would detach from the DNA before, then how would it make mRNA? That’s when we are left with Answer Choice A, which seems like the best Answer Choice.
Answer:
<h3>The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.</h3>
Superposition of strata
Younger
Cross-cutting relationship
Explanation:
Barry says the lowest part of the section must have been constructed before the parts above it based on the principle of superposition of strata.
Using the cracks, the cracks are younger than the wall; Barry used the principle of cross-cutting.
- Relative dating places rock strata based on geologic event.
- Several principle guides the application of this dating method.
According to the principle of superposition "in an undeformed sequence of rock strata, the oldest layer is at the bottom and the youngest on top".
The principle of cross-cutting states that "intrusion and faults are younger than the rocks they cut through".

Answer:
This question includes some errors, the question should be written as:
The medulla oblongata controls the contraction and relaxation of the ______ causing the lungs to inflate and deflate during breathing.
Although there are no options, the answer is generally RESPIRATORY MUSCLES i.e. diaphragm and intercostal muscles
Explanation:
Breathing is an involuntary action required to take place in order to get oxygen into the system and carbon dioxide out of the system. However, the process of breathing is neurally controlled by brain portion called RESPIRATORY CONTROL CENTERS.
The Medulla oblongata located in the hindbrain is one of the two respiratory control centers (the other being the PONS). The medulla sends nerve signals to the muscles responsible for bringing about the ventilation process i.e. the DIAPHRAGM and INTERCOSTAL MUSCLES.
This nerve impulse brings about the contraction of the diaphragm, which is the major respiratory muscle, and intercostal muscle causing the lungs to inflate and allow the entry of oxygen-containing air. On the other hand, it also brings about the relaxation of these muscles causing the lungs to deflate allowing the expelling of air.
