What is osmosis? Please help me
KIM [24]
First off, we need to understand that osmosis is typically used with the example of water---
To understand that, osmosis is taking water from a high concentration to a low concentration to make the membrane equal to one another .
Imagine you have a pea, and the pea is about to explode of water. And you have another pea that's shriveled up. You would take some of the exploding water's pea into the shriveled one, therefore making it equal. (Thats my example I like to use!)
I hope this helped!
