During heatstroke, the body can't dispose of excess heat. as a result, the homeostatic balance is disturbed, and internal body temperatures can reach as much as 110°. heatstroke is dangerous to people primarily because a. it causes pneumonia. b. blood vessels may rupture. c. blood pressure becomes too low. d. cells can't function properly at high temperatures.

option D - cells can't function properly at high temperatures.

Explanation:

Heatstroke is a severe case of abnormally high temperature in the body usually above 40.8°Celsius or 105.1 °Fahrenheit.

Cells function best at a particular physiological tempeature (usually 37°C), above which they malfunction.

Thus, at high temperatures cells can't function properly
