Answer:
it provides energy to the body.
The growth of rare earth metals market is driven by the rising use of the product as magnets in hybrid and electric cars and increasing shifts towards clean energy,
Billions of years ago, Earth's atmosphere lacked free oxygen.
Scientists call this a highly toxic atmosphere.
<h3>What kind of atmosphere was present on Earth in early times?</h3>
In the atmosphere of the primitive Earth there was no oxygen (O2) and nitrogen (N2), the air being composed of gases such as
- methane (CH4)
- ammonia (NH3)
- hydrogen (H2)
- and water vapors (H2O).
With this information, we can conclude that Early Earth's atmosphere may have been as toxic as that of Venus today. Earth is the only planet that harbors life (as far as we know)

During active transport proteins powered by ATP move substances up a concentration gradient. During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
