Question

As the forensic scientist on a poisoning case, Aaliya is conducting a color test on a sample from the victim. The victim was reportedly suffering from

headaches and nausea before a respiratory failure occurred. Which poison is Aaliya MOST likely testing for?
O A. arsenic
OB. cyanide
OC. strychnine
O D. ricin

Answer 1

Aaliya is most likely testing for cyanide poisoning, as the symptoms mentioned are consistent with early signs of this type of poisoning, which inhibits oxygen utilization in the body's tissues.

Step-by-step explanation:

Given the symptoms described in the case, such as headaches, nausea, and respiratory failure, Aaliya is most likely testing for cyanide poisoning. These symptoms align well with the early signs of cyanide exposure, which include headache, dizziness, fast heart rate, shortness of breath, and vomiting. Cyanide is a potent inhibitor of cytochrome c oxidase (Complex IV), a critical enzyme in the oxidative phosphorylation pathway. Therefore, cyanide poisoning leads to histotoxic hypoxia, as the body's tissues become unable to utilize oxygen effectively. Considering that cyanide can come from various sources, such as smoke inhalation from fires, exposure in workplaces, and certain insecticides, it's important to identify and confirm its presence quickly due to its high toxicity.

Answer 2

Step-by-step explanation:

Based on the symptoms mentioned, the poison that Aaliya is most likely testing for is B. cyanide. Cyanide poisoning can cause headache, nausea, and respiratory failure, which are the symptoms the victim reportedly experienced. Arsenic and strychnine poisoning can also cause headaches and nausea, but respiratory failure is not a common symptom. Ricin poisoning can cause respiratory symptoms, but it does not typically cause headaches and nausea.
