The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO).
<h3>Origin of the earth</h3>
The earth is believed to have originated in what scientists have referred to as the big bang in which several gases were formed.
The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO). The gases aggregated to form amino acids hence the origin of the initial life forms.

Explanation:
Palaeontologists study the fossil and once they found that the fossil of an organism in layer 2 and 3. The fossil present in layer 3 is very similar to the fossil present in layer 2.
From this, it could be concluded that the layer 3 possible might be evolved from the fossil present in layer 2. The fossil of layer 3 might be a close relative of the extinct fossil of layer 2 as they could have shared a common ancestor.
Many possibilities could be explained but these two are more valid.
Answer:It is this coupling of chemistry and movement that gives proteins the ... to place the protein in a particular location in the cell—an example is the SH2 ... At one level, the cell controls how many molecules of each enzyme it makes ... One of the best understood pump proteins is the calcium transport protein from muscle cells.
