Sometimes called earth's twins
Serhud [2]
My answer -

<span>There are typically two planets that are dubbed as Earth's twin. The first one, Venus, is called Earth's twin because of its similar size, and how it is the closest planet to Earth. But, scientists discovered that Venus's atmosphere and temperature were totally different from Earth's. The other planet also called Earth's twin is Mars. Mars is believed to have a large ocean on the past. Some even say that life may have developed on Mars for a short period of time. Furthermore, Mars has an average temperature of -70 degrees Fahrenheit, closest to Earth than any other planet. It seems that water and life define the Earth, and if Mars has these characteristics, it would truly be Earth's twin.


P.S

Have an AWESOME!! day :)

The creatine phosphate in the absence of oxygen provides phosphate to produce ATP. This provides greater mitochondrial power, in the rest the CP and ATP remain stored in the muscles. The enzymatic activity enhances with the phosphagen system.
