That is correct. They can transition from one gender to another at any time. The switch is determined by which is most suitable for mating at the time. Oysters normally begin as males and mature into females. Another fascinating oyster truth is that the substrate to which it attaches itself shapes this sea species!

Popsicles could end up being one of the world's most happy accidents if we have our way. According to National Public Radio, the magnificent summer treat was created in 1905 on a winter's night by a little boy by the name of Frank Epperson.

That's when a popsicle appeared!

A microphone can convert sound waves into electrical signals that fall and rise in a manner that is comparable to the sound wave pattern you are attempting to record. Analog recording techniques, which save sound wave patterns as a wavy groove etched into a plastic disc, can be used to store auditory waves. The model can also be saved as a magnetic print on plastic tape.

Climbers from all around the globe like putting their abilities to the test on climbs up these volcanoes.

Antarctic krill are not tiny, despite a common misconception. Yes, Antarctic krill (hence referred to as krill) are categorised as zooplankton, but they are not minuscule; they are larger than several commercially available shrimp species and are around the size of an adult human pinkie. In fact, this variety of krill's Latin name, Euphausia superba, implies that it is the largest and finest species of krill.

Clip-ins, believe it or not, are not a new idea; in fact, wigs and hair extensions date back to 3400 BC in ancient Egypt. Back then, wigs were sewn-on hair pieces composed of human hair and sheep wool. Beeswax and resin were used to glue and attach extensions, while the Egyptians used to lead and henna to colour their hair and sheep wool. Wigs and extensions were not quite as good quality or realistic as they are now, but the Egyptians had some incredibly elaborate braided and layered extensions.

The blue whale is the world's largest living creature, dwarfing even the largest dinosaurs. Blue whales can grow to be over 100 feet long and weigh more than 100 tonnes. Their hearts are the size of a small car and can weigh up to 1,300 pounds. Blue whales have massive arteries that pump blood through their massive hearts and into their vital organs, which is unsurprising. These arteries are so large that a fully grown human could swim through them; however, you should not attempt this.

Although no one knows for certain, it appears that cricket started in the hands of shepherds as a simple method to pass the time while protecting a sheep. Our first impression of cricket was that the cricket balls were made of cotton and that the bowlers' speed was likely unattainable. Cricket has been recorded in English history since 1597, when in a dispute over land possession, he cited the game of "creckkett." However, it took over ten thousand years until the first formal cricket match was held in 1877.

Brakes that do not lock up under full pedal pressure are becoming commonplace. They've saved numerous lives by letting the driver to keep steering the car and, hopefully, avoid a collision while braking hard. Mercedes-Benz improved the technology with Bosch in the 1970s before incorporating it into the S-Class in 1978. Anti-lock brakes were soon made standard on all Mercedes-Benz models.
