The cell membrane, also called the plasma membrane, is a selectively permeable membrane. The membrane is formed of a phospholipid bilayer and contains proteins that assist in cross membrane transport. The fluid mosaic model describes the way the proteins and lipids can flow along the surface of the membrane.

∙ 12y agoThe fluid mosaic model represents the structure of the plasma membrane. It shows that the plasma membrane consists of a phospholipid bilayer ( with hydrophilic heads- which face the interior and exterior of the plasma membrane- and hydrophobic tails) as well as transport proteins namely carrier proteins and pore proteins. The size and polarity of a molecule determines how it will pass through the semi-permeable plasma membrane whether by simple diffusion, osmosis, facilitated diffusion or active transport.

∙ 12y agohow the cell membrane works.
The cell membrane consists in eukaryotes out of a phospholipide bilayer with integrated proteins. The model shows, that the phosopholipids aren't fixed an glide along each other. Thus also the proteins in the cell membrane change their location constantly.
The fluid mosaic model was described after scientist in the 70s watched two cell membranes hybridize. They marked one cell and after they fused both together, they saw that the cell's phospholipids had mixed completley.
The fluid mosaic model also says that there happens to be so called "flip-flops", which means a phosolipide goes upside down and the part that lay inward before is now part of the other membrane.

What are the 2 models of evolution?
One model of evolution follows from simple to more complex forms as the life evolved. The other model states that in some cases the simplicity has resulted due to reduction. Both these models have sufficient examples to substantiate their view point.

What is the opposite view of the Theory of Evolution?
That depends on the aspect of evolutionary theory that you're focusing on.If it's evolution itself, the changing of life over time, then one might argue that the opposite is that life does notchange. Which is, of course, manifestly false.If it's the proposition of common descent, then one might postulate a model in which descent is uncommon - in which modern forms derive from separate origins. Which is contrary to the available data.If it's the proposition of natural selection, one might, for instance, posit that selection is unnatural - in some way.Evolutionary theory is a complex, coherent model consisting of a number of theses and observations. One might conceivably be able to formulate an opposite for any one of these theses or observations, but to ask somebody to formulate an opposite for the model as a whole is equivalent to asking 'what is the opposite of a skyscraper?'.
