There is definitely a strong relation between osmosis pressure and water activity. Osmosis is the movement of water from high pressure to low pressure.
concentration gradients, osmosis, and hydrostatic pressure
Water or liquid move naturally from lower concentration to higher concentration. The drive force is called osmotic pressure. No additional pressure need to drive osmosis process. Reverse osmosis, is apply pressure to fight against osmotic pressure. It do need additional pressure to reverse the osmosis process. It is comparing a zero additional pressure with any positive additional pressure thus of cause reverse osmosis require more pressure.
distillation
osmosis is affected by the concentration gradient the lower the concentration gradient the faster the speed of osmosis
Water enters into plants by Osmosis and water causes turgor pressure Tugor definition= the state of turgidity and resulting rigidity of cells (or tissues), typically due to the absorption of fluid.
Diffusion, Osmosis
a pressure greater than the osmotic pressure is applied in the opposite direction osmosis is occurring.
Enzyme activity, osmosis, and diffusion
The primary means of water movement between fluid compartments in the body is osmosis, which involves the movement of water across semipermeable membranes to maintain a balance of fluids and solutes between compartments. Additionally, water movement can also be influenced by factors such as hydrostatic pressure and oncotic pressure gradients.
It requires energy. With a pressure difference, you can revert osmosis.
The process of osmosis is reversed using high pressure to perform desalination.
