What creates selective permebility of plasma membrane?
It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
What is a function of the cell membrane that cannot be modeled with a plastic bag?
One function of the cell membrane that cannot be accurately modeled with a plastic bag is selective permeability. The cell membrane is selectively permeable, allowing only specific molecules to pass through based on size, charge, and other factors. This selective permeability is crucial for maintaining homeostasis within the cell and regulating the passage of nutrients and waste products. A plastic bag, on the other hand, does not possess the complex proteins and channels necessary for selective permeability and cannot accurately replicate this function of the cell membrane.
What best describes the structural arrangement of the plasma membrane?
The plasma membrane has a phospholipid bilayer structure composed of two layers of phospholipid molecules. Proteins are also embedded within this bilayer, serving various functions such as transport, signaling, and cell recognition. The structure allows for selective permeability, controlling the passage of substances in and out of the cell.
Why is it important that the root of endodermis permits only one way passage of materials?
Rate This Answer0 CommentsThe root endodermis permits only a one way passage of materials because the root doesn't want certain things entering. It's called selective permeability.
What is permeable tissue?
the definition of the of tissue permeability is: - The absorption of substances within the body tissues. cell permeability, which allows nutrients and other substances to enter the cells more readily and allows the removal of waste products from the cells.
When living things regulate their internal environment within limits that sustain life what is it called?
homeostatis

Why does the permeability of blood vessels increase during acute inflammation?
vasodilation causes increased pressure within the blood vessel which causes gaps within endothelium to form-this allows for the increased permeability.
What is the function of homeostasis?
Homeostatis is a function that maintains natural balances within the body. For example, temperature and water levels are kept controlled in the body.
Why does water have to pass through a transport protein?
The lipid bilayer in the cell cell membranes is essentially impermeable (or have a low permeability) to water and is necessary for cells to maintain their homeostasis. The water transport proteins and other transmembrane proteins are necessary for water to cross the cell membrane.
Why is permeability of ferromagnetic material is so high?
The high permeability of ferromagnetic materials is due to the alignment of magnetic domains within the material, which allows for easy movement of magnetic flux. This alignment creates a strong magnetic response to an applied magnetic field, leading to high magnetic permeability.

What is permeability in electromagnetism?
Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself.(Degree of magnetization that a material obtains in response to an applied magnetic field.) It is represented by the Greek letter μ.
Is a measure of the speed at which water can travel through porous soil or bedrock?
Permeability is a measure of how quickly water can move through porous soil or bedrock. It is determined by the size and connectivity of the pore spaces within the material, with greater permeability indicating faster water flow. Materials with high permeability, such as gravel or sandy soils, allow water to move more quickly compared to materials with low permeability, like clay or solid rock.
