When exposed to smoke, hydrogen cyanide may play a role in rendering firemen and bystanders incapable of performing self-rescue.
HCN is a toxin that spreads throughout the body; it is hazardous because it inhibits cytochrome oxidase, which stops cells from using oxygen. Loss of awareness, respiratory arrest, and finally death arise from inhibition of the last stage of electron transport in brain cells.
Higher HCN exposures cause cardiovascular collapse, tremors, cardiac arrhythmia (which may not manifest for two to three weeks after the fire exposure), coma, respiratory depression, and respiratory arrest. Inhaling minute concentrations of hydrogen cyanide can result in headaches, weakness, nausea, and vomiting. Larger doses might result in fainting, convulsions, gasping, fast pulse, irregular heartbeat, and even death. In general, the severity of the symptoms increases with the seriousness of the exposure.

People frequently overestimate the frequency of these situations since they are widely reported when they do occur.
The three heuristics that attracted the greatest attention were representativeness, anchoring and adjustment, and availability.
<h3>What is an example of availability heuristic?</h3>
- The availability heuristic prioritizes sporadic events according to their recentness and vividness. For instance, aviation accidents might cause people to fear flying. But the chance of dying in a car accident is much higher than the chance of dying as an aviation passenger.
- The accessibility Heuristic is a cognitive bias in which you make a choice based on information that is readily available to you, such as an example, information, or recent experience, even though it may not be the greatest example to guide your choice.
- When faced with an instant choice requirement, the availability heuristic enables people to make decisions fast. When you're attempting to decide or pass judgment on the world around you, this can be useful.

D, all of the above. The scientific method goes through the process of making a hypothesis, testing it, and reviewing the results. It goes through a full lab report.
