What are the functions of carbohydrates on the surface of the phospholipid bilayer of the cell membrane?
they are signaling devices that are used to identify what is near the cell
What bilayer covers a cells surface and controls what enters or leaves the cell?
whats a lipid bilayer that controls what comes in and out of the cell
What is the membrane a phospholipid bilayer?
It is the double wall of a cell membrane that regulates material passage. The cell membrane is called the phospholipid bilayer because the phospholipids form two distinct layers. In each layer, the phospholipid molecules lie with the hydrophilic "heads" at the membrane surface and the hydrophobic "tails" on the inside, in association with cholesterol and small quantities of other lipids.
What do you call a fractured surface on earth's crust where a mass of rock is in motion?
A fractured surface on the Earth's crust where a mass of rock is in motion is called a fault.
Function of peripheral proteins?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. Peripheral proteins are not bonded as strongly to the membrane. They may just sit on the surface of the membrane, anchored with a few hydrogen (H) bonds.
Which is NOT an important structural feature on the surface membrane of an animal cell?
lipid bilayer
What Controls what goes in and out of the cell?
The phosopholipid bilayer of the cell membrane controls what moves into and out of the cell based on receptors on the cell's surface.

What molecules are apart of the cell membrane?
A cell membrane is made up of lipids (the lipid bilayer) was well as glycoprotiens and glycocalyses. The proteins can be on either or bothe sides of the lipid bilayer, allowing for various types of transport through the "semi-permeable membrane." The proteins on the surface may be used for identification purposes.
Which part of a cell controls what gets in and out?
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
Why is a cell membrane composed of a bilayer of phosolipids?
That's the structure of a stable "soap bubble", it's the surface tension of the monomolecular layer of water between them that holds cells (and you) together.
What does th cell membrane do?
The cell membrane allows food, water and unneeded wastes to travel in and out of the cell (it kind of acts like a filter in a way). While protecting and supporting the cell in place. Cell surface membrane: phospholipids bilayer with protein forming a partially permeable membrane It restricts movement and supports shape.

How does gneiss feel?
A fractured surface--rough. A polished or worn surface--smooth.
What makes up the surface of a cell?
In a plant cell it is the cell wall. In an animal cell it is a cell membrane

A fractured surface on the Earth's crust where a mass of rock is in motion is called a fault.
