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.
Transcript of DIFFUSION, OSMOSIS, AND ACTIVE TRANSPORT. DIFFUSION, OSMOSIS, AND ACTIVE TRANSPORT. Today, I shall be explaining what Diffusion, Osmosis and Active Transport are, how they work, and their role in both plants and animals. OSMOSIS. Osmosis is the movement of water through na partially permeable membrane along a concentration gradient.
