(Someone please help me) When muscles are active, cells use nutrients and oxygen at a higher rate and produce waste chemicals and heat more quickly. Describe how the interaction of two or more body systems helps to maintain homeostasis during periods of high muscle activity.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
