Hydrophobic part
Explanation:
A protein is made up of amino acids. Some amino acids such as serine and threonine are polar and hydrophilic in nature as they have polar side chains. The other amino acids such as alanine and proline are non-polar as they have nonpolar side chains.
The polar amino acids of a polypeptide chain are folded towards the inside of the protein to avoid any interaction with the surrounding watery medium. On the other hand, the polar and charged amino acids are oriented towards the surface of a folded protein. This arrangement makes the proteins stable.
Beavers are descendants of land-dwelling rodents similar to rats. The beavers however have adapted their body shape to live in water bodies like ponds and lakes. This can be hypothesised by saying that the early rodents or the ancestors of beavers were forced to find food in the waters. They lacked the flat tail and the webbed feet. With time the need to increase their ability to catch fishes and floating insects, the rodents with flatter tail and a bigger flat webbed feet gradually evolved. The rodents with flatter tails and webbed feet became adjusted to the life on water and became the modern day beavers.
