Final answer:
A person who becomes dangerously overheated may face organ failure that can lead to death, as high body temperatures disrupt essential metabolic processes.
Step-by-step explanation:
When a person becomes dangerously overheated, such as during a heat stroke, they face the danger of organ failure which can lead to death. This is because extreme body temperatures can cause critical proteins like enzymes to lose their structure and function, leading to a breakdown in essential chemical reactions within the body. This results in the failure of metabolic processes which are vital for life, ultimately leading to organ failure.
