It causes it because the cell of the membrane are not moving. So therefore it is not moving.

What is a fluid mosaic model?
Simply put, the fluid mosaic model is a description of the membrane of a cell. The fluid part refers to the phospholipids of a cell membrane, which, like liquid, flow. The mosaic part refers to proteins embedded in the phospholipid bilayer that act as conduits through which molecules enter and exit the cell.____________The currently accepted model of cell membrane structure, which envisions the membrane as a mosaic of individually inserted protein molecules drifting laterally in a fluid bilayer of phospholipids.Fluid mosaic is a term used to describe the current model of the cell membrane.Cell membranes are basically double layers (bilayers) of molecules called phospholipids. 'Floating' in the phospholipid bilayer are molecules of protein. a mosaic is a structure made up of many different parts. Viewed from above the membrane would look something like a mosaic - a 'sea' of lipid with many 'islands' of protein.The lipid bilayer is not rigid, and the lipid and protein molecules are able to move sideways in the membrane i.e. the membrane is fluid.This model of the cell membrane was proposed by Singer and Nicolson in 1972, and has been supported by many experiments since then.model for cell membrane given by SJ singer and GL Nicholoson
Where should you use geotextile in roof above the membrane or below the membrane?
above waterproofing membrane and insulation
What part of the protein is within the membrane itself?
Ahh, the fluid mosaic model... any such above named protein is 'bound' to have three parts, or Regions. These are namely, the extracellular domain, the intracellular domain and the Trans-membrane Region. This latter is a segment of protein that is comprised mainly of non-polar amino acids that makes it particularly hydrophobic, suitable for residence within the bi-lipid layer.
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.
What is the altitude of polaris above the horizon at the tropic of cancer?
Polaris will be 23.5 degrees above the northern horizon when viewed from the Tropic of Cancer.
What does the fluid mosaic model describes?
It describes the structure of the cell membrane. It is called fluid because the individual phospholipid molecules can move freely within their own monolayer. It is called mosaic because of the pattern produced by the scattered protein molecules when the membrane is viewed from above.
Explain what a mosaic is and then explain why the term fluid mosaic model is used to describes the plasma membrane?
Fluid mosaic is a term used to describe the current model of the cell membrane.Cell membranes are basically double layers (bilayers) of molecules called phospholipids. 'Floating' in the phospholipid bilayer are molecules of protein. a mosaic is a structure made up of many different parts. Viewed from above the membrane would look something like a mosaic - a 'sea' of lipid with many 'islands' of protein.The lipid bilayer is not rigid, and the lipid and protein molecules are able to move sideways in the membrane ie the membrane is fluid.This model of the cell membrane was proposed by Singer and Nicolson in 1972, and has been suported by many experiments since then.Read more: What_is_meant_by_the_term_'fluid_mosaic'

Why is the cell membrane said to be a fluid mosaic?
Generally water and gases are described as fluid. In this context cell membrane is said to have a fluid mosaic model just because of it super flexible nature. Lipid bipolar molecules in the cell membrane can exhibit a flip flop movement. It can easily reseal after any breakage. So as fluid have an ease in changing their orientation likewise cell membrane posess a similar property. shankha LOL

What did the trilobite look like?
See the related link. The uppermost of the specimens is viewed as a cross section, and the lower is viewed from above.
What is countershading?
Counter shading is a common color pattern in animals in which the dorsal side (upper side) of the animal is darker than the ventral (lower) side. Such a color pattern provides camouflage for the animal when viewed from above, below, and even from the side.Sunlight shines down from the sky and illuminates the top of an animal's body, casting its belly in shadow. The counter shading pattern balances the light from above and the shadow beneath the animal so as to blend the animal's side profile with its surroundings.Counter shading also helps animals blend into their surroundings when viewed from above and below, which is the case for many tree-dwelling and aquatic species. When viewed from below, a counter-shaded animal with a light belly blends into the light coming from the sky above. When viewed from above, the darker back of a counter-shaded animal blends into the darker ground colors below.Examples of counter-shaded animals include:many species of shorebirdssome species of dolphinsnumerous species of fish
