What does the net flow of water molecules in osmosis depend on?
The magnitude of the concentration gradient across the membrane.
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What is the physical difference in the number of molecules between two regions of space A.concentration gradient B.plasma membrane C. receptor proteins D. phospholipid layer?
Concentration gradient.
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
What does the net flow of water molecules in osmosis depend on?
The magnitude of the concentration gradient across the membrane.
What is a diffused molecule from a semipermeable membrane?
What is the situation? Provided a concentration gradient and a molecule that passes through a membrane, diffusion will happen. Generally small and nonpolar molecules will pass through a membrane down a concentration gradient. That doesn't answer your question but it may be the answer your looking for.
When molecules such as oxygen are moved into Cells along their concentration gradient directly through the Cell membrane - this is called?
Trans-membrane diffusion.
If the concentrationof molecules on both sides of a membrane is the same the molecules will?
When the concentration of molecules on both sides of a semi permeable membrane are the same, there is no concentration gradient. Therefore, the system is at a state of equilibrium and the molecules remain static

Concentration gradient.
What is osmosis gradient?
Osmosis is the diffusion of water across a water permeable membrane. The gradient is the tendency of the water molecules to move from the side of higher concentration of water to the side with lower concentration of water in an attempt to achieve equilibrium.
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
