Answer:
its passive transport
Explanation:
The sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na+ and K+ at constant disequilibrium.
Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Once entering the atmosphere the heated up water vapor (that's the process of evaporation) cools back down (the atmosphere is cooler than the Earth you see). it makes clouds Their it will condense until it's heavy enough to fall to Earth as precipitation!
