What kind of bi layer is the cell membrane?
The cell membrane is a phospholipid bilayer, consisting of two layers of phospholipid molecules. Each phospholipid molecule has a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, creating a barrier that controls the movement of molecules in and out of the cell.
What molecule moves across the phospholipid layer through endocytosis?
In endocytosis, molecules like proteins, lipids, and even viruses can be engulfed by the cell membrane and transported across the phospholipid bilayer in vesicles called endosomes. These vesicles are then processed by the cell to release their contents into the cytoplasm.
What is a fluid mosaic?
It is a theory proposed S.J. Singer and Garth Nicolson in 1972 to explain the properties of a cell membrane. 1. Cell membranes are made of 2 layers of phospholipids. 2. A phospholipid is a large molecule, based on a triglyceride. It has a phosphate head which is water-loving and a fatty acid tail which repels water. 3. The phosphate head forms the outside of the layer and attracts water. 4. The fatty acid is repelled by the water and points towards the middle of the molecule: http://upload.wikimedia.org/wikipedia/commons/f/f0/Lipid_bilayer_section.gif Molecule is a part of the mosaic. If you looked at the membrane from above, it would look like a mosaic of phospholipid. The 'Tiles' are not joined and have gaps between them. Google Phospholipid Bilayer for more info.
Where is the youngest rock usually found?
in the middle of the ocean ridge
What does it mean when the cell membrane is a phospholipid bi layer?
Phospholipids are a structural component of the environment
Does plasma membrane have phospholipid layer?
A phospholipid bi-layer.
What are found in the stratosphere?
The ozone molecule in found in the ozone layer. It is an allotrope of oxygen molecule.
What is the primary molecule of the cell membrane?
The primary molecule of the cell membrane is a phospholipid. Phospholipids have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, which allows them to form a double layer in the cell membrane called the phospholipid bilayer.

What is the component of the plasma membrane of eukaryote cells?
Phospholipid bi layer mainly.Otherthan proteins,carbohydrates,lipids canbe found
What is a phospholipid bilayer and where would you find it?
Phospholipids are polymers made up of two fatty acids, glycerol, a phosphate group and a polar molecule. A cell's membrane consists phospholipids where they form two layers (with the polar molecules facing opposite ends) to separate the interior of the cell from the outside environment. This is called a phospholipid bilayer.
What molecule moves across the phospholipid layer through endocytosis?
In endocytosis, molecules like proteins, lipids, and even viruses can be engulfed by the cell membrane and transported across the phospholipid bilayer in vesicles called endosomes. These vesicles are then processed by the cell to release their contents into the cytoplasm.
The cell membrane is made of what double layer?
Phospholipid bilayer

What type of bi-layer does the cell membrane have?
It is a bi-layer of phospholipids, also called the 'phospholipid bilayer'.
Which organelle contains the most proteins suspended in a phospholipid layer?
Vacuoles
How is the ozone layer formed?
elemental oxygen is normally found in the form of a diatomic molecule. however, in the upper reaches of the atmosphere, a molecule containing three atoms of oxygen is found. this is called ozone!
