What else can I help you with?
Why is the cellophane membrane considered to be a selectively permeable membrane?
Only the water can enter into the bag and leave the bag, the tea leaves can not leave the bag.
Is a mirror selectively permeable?
A mirror is not selectively permeable. The mirror's surface is rigid since it cannot allow any substances to pass through it.
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.
How does oxygen cross a selectively permeable membrane?
diffusion
Cells have selectively what membranes?
Cells have selectively permeable membranes that allow certain substances to pass through while blocking others. This selectivity helps maintain the internal environment of the cell by controlling the movement of molecules in and out.
Why is the cellophane membrane considered to be a selectively permeable membrane?
Only the water can enter into the bag and leave the bag, the tea leaves can not leave the bag.
Cells have selectively what?
Selectively permeable.
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.
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).
What is the relationship between cell membrane and selectively permeable?
Cell membranes are indeed selectively permeable.
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.
Why is a plastic bag selectively permeable?
Does not allow matter to pass, but energy (light, heat, etc) is allowed to enter.
What is an example of a common item that performs similarly to a selectively permeable membrane?
cell walls are semi-permeable, that is, they selectively permit only certain things through.
Does the membrane of a cell is selectively permeable?
no
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.
Are cell walls and cell membranes selectively permeable?
Cell membranes are selectively permeable while cell walls are semi-selectively permeable. Keep in mind that only low level organisms, like plants, have cell walls.
Is the cell membrane selectively permeable?
There are different types of plastics and most of them are nor permeable or selectively permeable .Cellophane is a specific plastic used in biological experiments as it is selectively permeable .
