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.
My mind is Completely mush right now and I am drawing a blank here. Looking for two similarities and two differences between facilitated diffusion and osmosis. One similarity and two differences between facilitated diffusion and active transport.
