Answer:
Facilitated diffusion of solutes occurs through protein pores in the membrane.
Explanation:
Facilitated diffusion: It is known as a type a passive transport which diffuses the solutes through specific trans membrane integral proteins in the plasma membrane. Transport proteins helps in diffuse some ions, and molecules across the plasma membrane.
There are three types of transport proteins which are involved in this diffusion:
1) gated channel proteins.
2) carrier proteins.
3) channel proteins.
Some example of facilitated diffusion are: glucose transporter, ion channels, and aquaporins.
Alcohol risk that one is hard to answer sorry if i wasn't much help
Answer:
In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave.
