What else can I help you with?
What is a giant sphere with a light blue membrane that stretches across the entire surface of a cell?
That description fits the cell's plasma membrane, which separates the cell from its external environment and regulates the passage of molecules in and out of the cell.
What part describes the cell membrane structure because it is flexible and could be compared to an arrangement of tiles?
Fluid Mosaic Model
What is a description of cell membrane?
It encloses the cytoplasm, and is a protective barrier that controls what goes in and out of the cell.
What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
Explain why the term fluid mosaic model is used to describe the plasma membrane?
the arrangement of the molecules that make up a cell mebrane
What is a description of the cell membrane?
The cell membrane lets substances in and out of the cell.
The bilayer arrangement of molecules in a cell membrane give the cell a?
barrier
What would be appropriate for making the cell membrane in a cell model?
A good item for a cell membrane would be a thin plastic or cardboard
What is the description of endocytosis?
process of taking materials into the cell by means of infolding of the cell membrane

What is a description of the necleus?
Nucleus in an animal cell is a membrane covered sack which contains the cell's DNA. The DNA is the boss of the cell, and has the directions for forming a new cell.
What describes the cell membrane structure because it is flexible and could be compared to the arrangement of tiles?
Fluid Mosaic Model
Which technique can show that the cell membrane has two layers?
The technique that can show that the cell membrane has two layers is electron microscopy. By using transmission electron microscopy (TEM), the phospholipid bilayer structure of the cell membrane can be visualized, showing the double-layered arrangement of phospholipid molecules.
What part describes the cell membrane structure because it is flexible and could be compared to an arrangement of tiles?
Fluid Mosaic Model
How does cholesterol contribute to the structure and function of the cell membrane?
Cholesterol helps maintain the fluidity and stability of the cell membrane by preventing it from becoming too rigid or too fluid. It also plays a role in organizing the arrangement of lipids and proteins within the membrane, which is important for various cellular functions such as cell signaling and transport.
What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
