Water moves down its concentration gradient when: A. there is not enough water in the ICF B. there is not enough water in the ECF C. there are more permeable solutes on the other side of the membrane D. there is a concentration gradient of water because there is a difference in the number of non-permeable solutes on one side of a membrane compared to the other side. 5. Solutes driven by the process of osmosis could cause a cell to swell or crenate. A. True B. False 6. Amino acid are linked together to form peptides and proteins for use in the body.
