Which one of these is not an example using facilitated diffusion?
aquaporins facilitate the diffusion of water in the kidney tubules of many
mammals.
a carrier protein moves sucrose across the membrane with the
concentration gradient.
using the sodium-potassium pump involves the hydrolysis of atp and the
release of nat to the outside of the cell.
ca+2 moves from high cytoplasmic concentration to low concentration
inside the cell using a membrane-spanning protein.

C. "Using the sodium-potassium pump involves the hydrolysis of ATP and the

release of Nat to the outside of the cell."

Explanation:

The use of a sodium-potassium pump is a form of active transport, not diffusion. It also requires energy because the pump moves ions against their concentration gradient (low to high), unlike diffusion.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
