Which mechanism is a typical mammalian physiological response when surrounding tomperatures fall significantly below the body temperature? A. Shivering muscle activity produces heat B. Increasing blood flow to the skin surface stimulates heat absorption C. Maximizing the evaporation rate from body surfaces through sweating D. Panting to increase the airflow over a moist surface to dissipate excess heat

The correct answer is A. Shivering muscle activity produces heat.<br /><br />When surrounding temperatures fall significantly below the body temperature, a typical mammalian physiological response is shivering. Shivering is an involuntary muscle activity that generates heat to help maintain the body's core temperature. This response is triggered when the body senses a, contract rapidly to produce heat. This heat helps to and stable internal temperature.
