For a 2 year old patient who was severely dyspneic and now unresponsive and no longer breathing, you will instruct your EMT to insert an OPA and begin give positive pressure ventilations with a BVM with 100% O2 to the patient. Palpate for a pulse and if <10 seconds you cannot feel a pulse, you will begin chest compressions.
The good thing about respiratory codes in children is that they normally always code due to lack of oxygenation. Once they are finally re-oxygenated, they will typically come around with better vitals.
Answer:
The correct option is option C, nucleus
Explanation:
As the scenario described in the question, the medicine X functions on the DNA as it's characteristic shows that it is damaging the DNA. The DNA is present inside the nucleus of a cell. Hence, for a medicine to function on the DNA, the medicine must enter the nucleus of the cell as it is the location where the DNA is present.
Other options like, option D, is not correct because the process of conversion of mRNA into proteins takes place in the ribosomes and DNA is not present there.

Answer:
A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes
Explanation:
Endosymbiont theory deals with how eukaryotic organisms were formed from prokaryotic organisms. Prokaryotes such as Bacteria were documented as the first form of life on earth through fossil records before eukaryotes came into light.
Organelles such as Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes. This supports the endosymbiont theory that present-day eukaryotic cells are descendants of a successful symbiotic relationship between a host cell and an engulfed prokaryote
