How does random motion create directed movement in the cell?

Several molecules must work together for proper joint lubrication. In this illustration, the lubricin molecules anchor the long hyaluronan chains to the cartilage collagen network; these hyaluronan chains in turn attach the phospholipid molecules in either single layers (green) or double layers (blue)

A chicken heart muscle cell under a fluorescent microscope; the filaments consist of repeated subunits (bright dotted lines). The schematic representation shows three neighboring filaments; the black lines are the boundaries of their subunits, such that the lower filament is aligned with the middle one, while the upper one is not

A satellite image of Olympus Mons, Mars, the largest volcano in the solar system at about three times the height of Mount Everest. Around 3.5 to 4.0 billion years ago, the release of volcanic gases, especially the greenhouse gas sulfur-dioxide, may have warmed the surface of Mars episodically, thereby explaining the presence of geomorphological features indicative of the flow of water on the planet's ancient surface
