The steam that can be seen coming out of a boiling kettle consists of condensing water droplets. These water droplets move upward with the hot water vapor coming out of the kettle. The process of hotter air rising and cooler air falling is called convection. What role does convection play in the atmosphere?
A. Convection makes the air warmer at higher altitudes.
B. Convection currents distribute heat in the atmosphere.
C. Convection prevents the air in the atmosphere from moving.
D. Convection transfers heat from the atmosphere to the ocean.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

a covalent bond, specfically triple bond
