Phospholipids will form a bilayer in water because they contain hydrophobic (Water fearing.. in this cause water "hating") tails and hydrophilic heads (water loving). So they form a bilayer to remove the tails from water likewise, this satisfies the hydrophilic heads because they are still exposed to water.

Explanation:
The water slowly takes off minerals of the rocks every time is splashes over them. Over time the rocks bumpy surface would be eroded away giving it a smoother surface.
It will all make more sense if you start from the beginning of the sequence with the structure of DNA. You will remember that messenger RNA contains a sequence of bases which, read three at a time, code for the amino acids used to make protein chains. Each of the sets of three bases is known as a codon.
