Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins.
<span>In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.</span>

Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.
