Answer:
Explanation:
Helium is the second most abundant element in the universe, but here on earth, it's rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Helium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas.
Helium is generated underground by the radioactive decay of heavy elements such as uranium and thorium. Part of the radiation from these elements consists of alpha particles, which form the nuclei of helium atoms. ... Helium can also be produced by liquefying air and separating the component gases
When the gas contains more than about 0.4% helium by volume, a cryogenic distillation method is often used in order to recover the helium content. Once the helium has been separated from the natural gas, it undergoes further refining to bring it to 99.99+% purity for commercial use.
Answer:
No the atomic mass is the same as the atomic number
Explanation:
It would be UGCCAG. This is because in mRNA, thymine is replaced by Uracil. That means the complementary base pairings are uracil and adenine (instead of thymine and adenine in DNA) and cytosine and guanine. So you need to change them to the other base in the pair. Meaning A (adenine) becomes the base it is paired with, being Uracil in this case and so on.
Answer:
because it is a moon of Saturn
because it is covered in ice
because it has a deep ocean beneath ice
because there is a chance it hosts life
because it has an atmosphere similar to Earth
Explanation:
In photosynthesis, using light energy, plants convert CO2 and H2O into O2 and C6H12O6
CO2= carbon dioxide
H2O= water
O2= oxygen
C6H12O6= glucose
