Symptoms of the prolapsed uterus can include feeling like something is coming out even though you aren't having a baby, lower back pain, trouble using the bathroom and painful intercourse. Lower back pain has lots of causes, but I've never heard of this particular one.
Facilitated diffusion is a passive process: The solutes move down the concentration gradient and don't use extra cellular energy to move. Channel proteins are another type of facilitated diffusion that allow the selective transport of one type of hydrophilic molecule across the cell membrane.
The three types of diffusion in an independent cell are simple  diffusion, facilitated, and active. The function of simple  diffusion is to transfer oxygen. Facilitated diff â¦ usion transports  water or non polar molecules.Active diffusion transports materials  against the concentration gradient.he function of simple  diffusion is to transfer oxygen.
