The earth was once formed by molten layers of the earth and over time layers began to form due to the relative melting points. hope this helps :D
The new hydrophilic amino acid would not form the same interactions with hydrophobic R groups. As a consequence, protein's 3D structure would likely be affected.
Different types of amino acids have different properties and thus form different interactions. For example, hydrophobic amino acids (water-repelent) such as alanine, valine, leucine, isoleucine, proline, phenylalanine, cysteine and methionine. participate in van der Waals type of interactions. They often form the hydrophobic core of the protein which doesn’t interact with water surrounding.
On the other hand, hydrophilic amino acids (arginine, asparagine, glutamine, aspartat..) are polar, can dissolve in the water and can join the hydrogen bond network.
<span>The word from the pick list that fits here is "enzyme". Enzymes are normally spcialised protein molecules and they act as catalyst ie agents to speed up a reaction in causing traits to develop in the genes of organisms in reaction to chemical stimulants.</span>
B I think(sorry if you get this wrong)
