User: Many animals have body symmetry with distinct front and back ends. This type of symmetry is A. unilateral symmetry.
Cumulonimbus, from the Latin cumulus (heap) and nimbus (rainstorm, storm cloud), is a dense towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents.
This can also occur on nimbostratus clouds (stratus nimbostratogenitus) and on cumulonimbus clouds (stratus cumulonimbogenitus). Stratus fractus clouds can also form under the base of precipitation-bearing clouds and are classified as pannus clouds. Mutatus mother cloud. Stratus only has one mutatus mother cloud.
