The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness...
For example, myelin contains 18% protein and 76% lipid.
In the case of a lunar eclipse, red light can pass through the Earth's atmosphere and is refracted - or bent - toward the Moon, while blue light is filtered out. This leaves the moon with a pale reddish hue during an eclipse.
Regional metamorphism takes place when rocks are buried deep in the crust. It is commonly associated with convergent plate boundaries and mountain range formation.
In other words<em><u> regional metamorphism takes place over wide areas and results from both pressure and temperature generated at convergent plate margins during subduction and continental collision.</u></em>
It results in deformation in non-hydrostatic and differential stress conditions and creates strongly foliated metamorphic rock (slates, schists, gneiss)
