### How many dogs years are in 1 human year?

But the conventional wisdom that one dog year equals seven human years is an oversimplified view of how old your dog is in human years. Although a dog’s age averages out this way, there is quite a bit of variation. For example, dogs mature more quickly than children in the first couple of years.

While it may be tempting to brush off warnings against looking up at this eclipse bare-eyed, don’t: The light of an eclipse really can damage your eyes — though warnings of total blindness are likely overstated.

By one year of age, that amount drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water.

Hence, Earth circumference is 2*Pi*r is about 40,030 km. Now is up to you to decide the amount of running per day. If you run a marathon 42.2 km per day, you’ll be done in around 2.5 years.

Apollo 11 was the spaceflight that landed the first humans on the Moon, Americans Neil Armstrong and Buzz Aldrin, on July 20, 1969, at 20:18 UTC. Armstrong became the first to step onto the lunar surface six hours later on July 21 at 02:56 UTC.

Fish need oxygen too, but since they don t have lungs, they take oxygen from the water in which they live. The oxygen in the water available to fish is called dissolved oxygen (oxygen that is dissolved in the water). Fish use gills to take oxygen from water just as we use our lungs to take oxygen from the air.

Candy store owner David Bradley’s shop was flooded during a major storm in 1883. As a result of the flood, his entire stock of taffy was soaked with salty Atlantic Ocean water. When a young girl came into his shop and asked if he had any taffy for sale, he is said to have offered some “salt water taffy.”

Antoine Lavoisier (lah-vwah-ZHAY), 1743-1794, introduced quantitative measurement into the study of chemistry with his discovery of the law of conservation of mass. He discovered the role of oxygen in combustion and established the principles for naming chemicals. He wrote the first modern chemistry textbook in 1789.
