It’s d I think I’m not sure
Tbh I don’t know. Sorry ❤️❣️
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
Cell membrane is made up of Lipid Bilayer which are fluid in nature , means they move continuosly , due to this fluid nature they are selectively permeable to compounds.
