The terms "polar" and "nonpolar" describe the ways in which individual particles of matter, or atoms, interact with water in a living organism and the ways in which groups of atoms that are stuck together, or molecules, interact with water. Annual Rev Microbiol 58:649–690. Because water is a polar solvent, and like dissolves like, these non-polar amino acids are hydrophobic, and tend to occur more commonly in the interior of proteins or in contact with non-polar membranes.

The term “glacier” comes from the French word glace (glah-SAY), which means ice.Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets. There are two key requirements for glaciers to form:. What does polar glacier mean? Straka RP, Stokes JL (1960) Psychrophilic bacteria from Antarctica. Not logged in Priscu and Christner (2004) calculated the total number of bacterial cells in the Antarctic and Greenland ice sheets to be 9.61×1025, which corresponds to a significant carbon pool of 2.65×10−3 Pg (1 Pg = 1015 g) and represents a considerable reservoir of microbial diversity.

Low temperature: for a glacier to form temperatures need to be low enough for snow to remain all year round, this is why glaciers tend to be found only at high latitudes (polar regions) and at high altitudes (in mountain ranges).
