What else can I help you with?
Is the tendency of water to move from an area of higher water concentration to one of lower water concentration.?
osmosis. The water moves down an osmotic gradient from a dilute solution of ions to a move concentrated solution through a partially permiable membrane.
Use of hydrostatic force to move fluids through a membrane?
There are many mechanisms for water to move through a membrane. Passive diffusion (osmosis) and facilitated diffusion are common biological processes. Sometimes a fluid like water can be forced through with hydrostatic pressure (water pressure), although this is less common in normal physiology.
How do water molecules move through the cell membrane during omosis?
With a specific channel protein called aquaporins.
Which molecules are often embedded within the lipid to help substances move through the membrane?
Cholesterol and proteins are often embedded within the lipid bilayer to help substances move through the membrane. Cholesterol helps to stabilize the membrane's fluidity, while proteins act as channels or carriers for molecules to pass through the membrane.
What organelle moves substances across the cell in one direction?
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
What is the difference between osmosis and reverse osmosis?
Osmosis is the tendency of fluids to pass through a membrane with equal concentrations on both sides. Reverse osmosis is forcing fluids through a membrane with a lower concentration on one side than the other.
What is the tendency of a solvent to move through a thin porous membrane from a dilute solution to a more concentrated solution?
If the solvent is water, it would be osmosis.
How does diffusion occur through a semipermeable membrane?
Diffusion through a semipermeable membrane occurs when molecules move from an area of high concentration to an area of low concentration, passing through the membrane. This process is driven by the natural tendency of molecules to spread out and reach equilibrium. The semipermeable membrane allows only certain molecules to pass through based on their size and charge, regulating the movement of substances across the membrane.
Can water move through the middle of a membrane?
Yes, water can move through the middle of a membrane through a process called osmosis.
How does the process of flux through a membrane contribute to the movement of substances across biological barriers?
The process of flux through a membrane helps substances move across biological barriers by allowing them to pass through the membrane from an area of high concentration to an area of low concentration. This movement is driven by the natural tendency of substances to reach equilibrium, where the concentration is the same on both sides of the membrane.
What forms osmosis?
the tendency of a fluid, usually water, to pass through asemipermeable membrane into a solution where thesolvent concentration is higher, thus equalizing theconcentrations of materials on either side of themembrane. the diffusion of fluids through membranes or porouspartitions. Compare endosmosis, exosmosis.
What is the tendency of water to move from an area of higher water concentration to an area of lower concentration?
osmosis. The water moves down an osmotic gradient from a dilute solution of ions to a move concentrated solution through a partially permiable membrane.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
What is pressure is equal to the tendency of water to enter one solution from another due to a concentration gradient?
Osmotic pressure is the tendency of water to move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. This process helps to equalize the concentration of solute particles on both sides of the membrane.

What is the protein binds to Particle and uses energy to move through the cell membrane?
protein binds to a particle and uses energy to move through the cell membrane
