Answer:
In the case study of the Chicago cyanide murder, the oxygen levels were very low which lead to the death of the cells in the body (there would be signs of dead cells in the victims' bodies).
Explanation:
The mitochondrion is the powerhouse of all cells in the animal body, it is responsible for cellular respiration and production of adenosine triphosphate or ATP.
When the cyanide stops the activities of the mitochondrion, each cell in the body begins to die as a result of hypoxia, which is a condition where the body or a part of the body is deprived of oxygen.
