Question

which of the following processes would ensure homeostasis using positive feedback? a high fever that raises the metabolic rate shivering to increase body temperature a persons blood pressure drops when they stand, causing the heartbeat to accelerate vasodilation to decrease body temperature

Explanation:

Positive - feedback loops amplify a physiological change rather than reverse it to maintain homeostasis. A high - fever raising the metabolic rate is an example of a positive - feedback mechanism. Shivering, blood - pressure regulation, and vasodilation for temperature control are negative - feedback mechanisms that work to restore the body to a stable state.

Answer:

A. A high fever that raises the metabolic rate
