Answer:
A hammerhead shark that gave birth in a Nebraska aquarium reproduced without mating, a genetic analysis shows. This form of asexual reproduction, called parthenogenesis, has been found in other vertebrate species, including some snakes and lizards. But this is the first time it has been documented in a shark.
Am certain that Creatine phosphate functions in the muscle by storing energy that will be transferred to ADP to resynthesize ATP. All muscle cells have a little ATP within them that they can use immediately, however, only enough to last for about 3 seconds. Therefore, all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly.
