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.
 
        
             
        
        
        
I think you're talking about histones. Histones are proteins found in eukayotic cell nuclei. Histones are what DNA wrap around so it fits inside the nucleus and helps with the formation of chromosomes.

Answer:
Chloroplast
Explanation:
This organelle in cells indicates that an organism can harness energy from the sun and other abiotic factors like carbon dioxide to make their own ‘food’. Chroloplasts have chlorophyl piments that contains photosystems centers that harness energy from the sun for photosynthesis. This light energy from the sun is captured and transferred in chemical bonds of manufactured carbohydrates which are stored in the plants. These plants transfer this energy in an ecosystem when they are consumed by higher organisms in the food chain.

- Use 2 identifiers.
- Ask patient to identify himself/herself.
2. Right medication
- Check the medication label.
- Check the order.
3. Right dose
- Check the order.
- Confirm the appropriateness of the dose using a current drug reference.
4. Right route
- Again, check the order and appropriateness of the route ordered.
- Confirm that the patient can take or receive the medication by the ordered route.
5. Right time
- Check the frequency of the ordered medication.
- Double-check that you are giving the ordered dose at the correct time.
- Confirm when the last dose was given.
6. Right documentation
- Document administration AFTER giving the ordered medication.
- Chart the time, route, and any other specific information as necessary. 
7. Right reason
- Confirm the rationale for the ordered medication.  What is the patient’s history? Why is he/she taking this medication?
8. Right response
- Make sure that the drug led to the desired effect.  If an antihypertensive was given, has his/her blood pressure improved?
-  Does the patient verbalize improvement in depression while on an antidepressant?
