Answer:
They all came from the big bang.
Explanation:
Fish breathe by drawing water in their mouths and forcing it out of the body via a number of gill slits. The gill slits are rich in blood vessels, enabling the direct absorption of oxygen. While all fish have gills, some fish are also able to extract oxygen from the air via gulping.
Most fish have swim bladders that are permanently sealed, but other fish have swim bladders that can hold varying amounts of air. Salmon have open swim bladders, and they must gulp air at the surface to keep them full. Some fish, such as sharks, lack swim bladders entirely. This causes them to sink if they do not maintain forward motion.
Fish have fins that are adapted to their lifestyle. Some have evolved into long, barbed structures, suitable for defense. Other fish have fins suited for achieving great speed or for walking along the bottom of the ocean.

Answer:
Where to Find Gold
According to estimates, all of the gold ever mined in the history of humanity amounts to about 152,000 metric tons. This sounds like a lot, but it is only about enough to fill up 60 trailers. Scientists believe that there is still eight times more gold in and under the oceans than has ever been mined close to the planet’s surface. Like the gold that is probably floating in the Earth’s molten core, most of this supply of the precious metal is inaccessible or simply too expensive to mine. Interestingly, gold has been discovered on all of Earth’s continents except for Antarctica. Of course, it is possible that even that continent holds some gold under all of the ice.
