High stratocumuliform clouds of the genus cirrocumulus form when moist air at high tropospheric altitude reaches saturation, creating ice crystals or supercooled water droplets. Limited convective instability at the cloud level gives the cloud a rolled or rippled appearance.
Some solutions found in living organisims are Carbon, Nitrogen, Oxegyn, and Hydrogen.
The remains of once living organisms found in sedimentary rock are called fossils. The most common elements found in living organisms are carbon,  hydrogen, oxygen, nitrogen, sulfur and phosphorous. These elements  are essential in order to sustain life.
