Hemp and marijuana plants contain another important cannabinoid: CBD. Hemp plants produce more CBD than THC, while marijuana produces more THC than CBD. Interestingly, research has shown that CBD acts to reduce the psychoactive effects of THC, separating hemp further from marijuana.emp and marijuana plants contain another important cannabinoid: CBD.

The reproductive organs of the male are different than that of a female hammer head shark. The males contain claspers which are elongated pelvic fin edges. The females contain a cloaca which is an opening that serves the digestive and reproductive functions.
1 This work has identified another remarkable example of convergence in the biological realm and, with it, raises questions about the validity of the evolutionary paradigm. Sperm Whale Bouyancy. The spermaceti, a large organ in the sperm whaleâs head, helps control this behemothâs buoyancy in the water.The organ contains a vast amount of fatty materials. When the whale is at the surface, the fat exists in liquid form. The fat solidifies when cold water enters the organ and restricts blood flow.rom an evolutionary standpoint, it looks as if an identical buoyancy control mechanism evolved independently in sperm whales and copepods. The very nature of the evolutionary process rests on sequences of improbable, chance events; thus, it should not generate identical outcomes multiple times.
