<prompt> A 10-degree decrease in temperature causes decreases in cerebral metabolic rate by :10305070  <response>: D i.e. 70With each degree fall in temperature, the metabolic rate is reduced by 70.So by reducing temperature by 10-degree celsius, the metabolic rate is reduced by 70.Cerebra coex is protected for 10 mins at 30-degree celsius and for 1 hr at 15-degree celsius.
