There once were lush forests and a variety of terrestrial and aquatic habitats that today are found only at much lower latitudes. Churchill, manitoba and resolute, nunavut are home to enormous numbers of fossil brachiopods. Puijila darwini, an extinct mammal that is thought to be a transitional form in the evolution of modern seals. Osmosis is the passive movement of water across a membrane from a solution of low solute concentration to a solution of high solute concentration. The terms hypertonic , isotonic , and hypotonic describe the effect that solutions have on cells. When tissues are exposed to temperatures below freezing, ice crystals form in the extracellular fluid and they reduce the amount of free water outside the cell, which creates an increase in osmotic pressure. Osmosis occurs from a solution with lower osmotic pressure to one with higher osmotic pressure.
