Today scientists know that on average the ocean is 2.3 miles (3.7 km) deep, but many parts are much shallower or deeper. To measure depth they use sonar, which stands for Sound Navigation And Ranging. A ship sends out pulses of sound energy and measures depth based on how quickly the sound travels back.

An instrument used in measuring the depth of water by the time required for a sound wave to travel from surface to bottom and for its echo to be returned. It may also be used for measuring the rise and fall of the tides in offshore localities.

Choosing Appropriate Units of Measure

A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water. There are two yards (6 feet) in an imperial fathom.

What’s the smallest organ in the human body? You’ll find the pineal gland near the center of the brain, in a groove between the hemispheres. It’s not an organ like those in the abdominal cavity.

In males, nerve cell or a neuron and specifically motor neuron is considered to be the largest cell in the body. It is also the longest cell in the human body. It possesses a length of about 1 metre and a diameter of 100 microns.

The liver is the largest gland in the body and is an accessory organ of the disgestive system.

Here’s how the story goes: Every seven years (or 10, depending on which story you hear) we become essentially new people, because in that time, every cell in your body has been replaced by a new cell. There’s nothing special or significant about a seven-year cycle, since cells are dying and being replaced all the time.

The Top Four Elements Found in the Human Body Of the elements found in the human body, four of them make up the largest percentage of our body weight (96.2%). The four elements are oxygen, hydrogen, carbon, nitrogen.

Plenty of elements on the periodic table can be found in the human body, and gold is no exception. An adult human body weighing 70 kg contains about 0.2 milligrams of gold.

Pure gold is chemically inert and passes through the human digestive system without being absorbed into the body. Since 24-karat gold is very soft and fragile, most edible gold—whether leaf, flakes, or dust—also contains a little bit of silver, which is also inert.

Gold is a noble metal and for this reason it does not react inside human bodies. This means that it is not absorbed during the digestion process, so it is safe to eat. Purity of edible gold must be 23–24 karats, above that used in typical jewelry, which may contain other metals and can be toxic if consumed.

According to TIMES, Stanford economists Stefanos Zenios and colleagues have demonstrated that the average value of a year of quality human life is about $129,000. It concludes that the grand total of material cost for a typical human body is a meager $160. The result: theoretically, your body worths up to $45million.

Selling hearts, kidneys and tendons for transplant is illegal. But no federal law governs the sale of cadavers or body parts for use in research or education. Few state laws provide any oversight whatsoever, and almost anyone, regardless of expertise, can dissect and sell human body parts.

03/4​Is edible gold safe? Gold has been used since ancient times in medicines, dentistry and as a food decor ingredient. Scientifically, gold is inert and doesn’t break down easily. In fact according to experts, pure edible gold doesn’t break down and dissolve in the bloodstream.
