Gas turbines provide a means of transferring energy from a pressurized fluid to mechanical energy in the form of a rotating shaft. The gas turbine compresses ambient air in a compressor and then channels the compressed air into a combustion chamber.
The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene of Colombia is indistinguishable from modern cane toads from northern South America.he cane toad is native to the Americas, and its range stretches from the Rio Grande Valley in South Texas to the central Amazon and southeastern Peru. This area encompasses both tropical and semiarid environments.
1 1. 2  The invasion of cane toads through Australia kills many large predators, that are poisoned when they try to eat large, highly toxic toads.3  2. 4  But most native species are not affected by toads, because they soon learn not to eat them; or else have a pre-existing tolerance to the toadâs poison.
