When we think of membrane transport, we often think first of ATP-dependent, active mechanisms. However, it is also true that passive diffusion of ions and molecules plays an important role in many physiological systems. For each of the following situations, indicate whether ACTIVE or PASSIVE membrane transport is used, or if BOTH forms of transport may be used.

Match the descriptions to the terms in the list below. Assume nothing: choices may be used more than once, or not at all. More than one listed answer may be correct.

Select the equations used when solving the above problem:  (The original problem: A concrete cube with side 2.00 m and emissivity 0.55 is heated to T.  If the ambient temperature is 25.0°C, what net power (in kW) does the cube radiate?  

An underground gasoline tank can hold {V} gallons of gasoline at 52.0°F.  The tank is being filled on a hot day by a truck when the outdoor temperature is {T}°F.  How many gallons of gasoline from the truck can be poured into the tank? Assume the temperature of the gasoline quickly cools from {T}°F to 52.0°F upon entering the tank. (The coefficient of volume expansion for gasoline is 9.6  10-4 (°C)−1.)

For a physics experiment, a solid cube is suspended from a spring scale. The gravitational force exerted on the cube is 0.714 N as measured when the object is suspended from a spring scale. When the suspended cube is submerged in water (ρ = 1000 kg/m3), the scale reads 0.450 N.   What is the mass of the object in g (grams)?
