What happens when the number of water molecules is greater in one area than another area?

Water molecules, of course, also diffuse. They move across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. This process is called osmosis.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
