Answer:
only if you give me a brainliest!!!!
Explanation:
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.

Answer: Level of processing
Explanation:
This experiment shows that the level of processing is very important when it comes to memory.
The group of words when related to its meaning is remembered more efficiently as compared to the group of words without meaning.
The reason is level of processing which states that memory depends on how the information is programmed into the mind.
Deeper the processing better encoding so group B had a better retrieval as compared to group A.
The Louisiana Purchase is important because it gave the U.S. control of the Mississippi River and the port city of New Orleans, both of which were used by farmers to ship their crops and get paid.
