If a 10 percent sugar solution is separated from 20 percent sugar solution by a selectively permeable membrane in which direction will there be net movement?

The direction will be towards the more concentrated side so the 10% solution with go towards the 20% solution in an attempt to reach equilibrium.

What are the real world applications of tonicity?
Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. In other words, tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution.
What does flaccid mean?
flaccidity is when a cells absorbs water and goes soft and limp the water is absorbed through a partially permeable membrane but does not burst because it is protected by a cell surface membrane.Another Answer:limp, soft, or lacking firmness, lacking vitality, lacking energy, or enthusiasm.
What are three things found in a plant cell that are not found in an animal cell?
A Cell Wall.
What are the four functions of membrane proteins?
no one cares
What is a real life example of a nuclear Membrane?
The ozone or an eggshell
A membrane that allows some substances to pass through while excluding others would be called a?
selectively permeable membrane.
How is dialysis membrane selectively permeable?
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Does the membrane of a cell is selectively permeable?
no
What is the relationship between cell membrane and selectively permeable?
Cell membranes are indeed selectively permeable.
What does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
What is definition of selectively permeable?
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
Are cell membranes selectively permeable?
The membrane is selectively permeable because it has specific instructions on what the membrane can allow through based on the How_is_the_cell_membrane_semi_or_selectively_permeable, size, and ionization of the particle.
How cell membranes selectively permeable?
The membrane is selectively permeable because it has specific instructions on what the membrane can allow through based on the How_is_the_cell_membrane_semi_or_selectively_permeable, size, and ionization of the particle.
What is a membrane that allows some substances to pass through but excludes others?
A selectively permeable membrane allows only certain molecules or ions to pass through while blocking others based on size, charge, or other specific properties. This allows for regulation of what enters and exits a cell or organelle.
Do all cells have a membrane?
Cells have impermeable, permeable and selectively permeable membranes.
