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.

<span>The process of gender role development.

Answer:
citric acid cycle intermediates
Explanation:
Many citric acid cycle intermediates can be siphoned off and thus can be used to generate the amino acids. The intermediates which can provide carbon skeletons for the synthesis of the amino acids are oxaloacetate which helps in the formation of aspartate as well as asparagine; and alpha-ketoglutarate which helps in the formation of the glutamine, proline, as well as arginine.
<span>The correct answer would be C. Cardiopulmonary resuscitation, commonly
known as CPR, is a procedure used in an emergency situation. An effort to
manually preserve intact brain function is performed until additional actions
are taken to bring back natural blood circulation and breathing in a person who
is in cardiac arrest. It is immediately performed in those who are impassive
with no breathing or abnormal breathing, for example, those who have just
drowned. Basically, CPR is performed in order to let oxygenated blood flow
through the heart and brain.</span>
Gender schema encourages stereotyping due to the teachings of the customs/traditions of the cultures they’re brought up in. for example, some cultures like in the middle-east teach children that women should stay in the house, cook, clean & be modest, whereas other cultures such as switzerland, denmark, and sweden teach children that women have the same rights as men and can live the lifestyle she wishes to live. this encourages stereotyping as some cultures stereotype a persons gender and automatically give them “roles” due to their gender.
