The possible answers are:
A. Variation in length of the amino acid backbone
B. Each protein is encoded by a distinct gene
C. Variations in the type of peptide bond
D. Variations in the glycosidic linkage
E. Variation in tertiary structure
<span>F. Variations in which amino acids are used
The correct answers are A,E and F
There are only 20 amino acids that make all of the proteins in our bodies. However, there are options for protein variation are almost unlimited.
Firstly, you can vary the number of different amino acid that you use to make a protein.
Secondly, you can also vary the length of the amino acid chain.
And thirdly, when an amino acid chain is formed different parts of the chain interact with each other, bonding chemically, forming different 3-dimensional structures of the protein.
All of this contributes to the vast variation in proteins.</span>

The Foucault Pendulum show that the Earth rotates because the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.
<h3>How does the Foucault pendulum work?</h3>
The Foucault pendulum was able to demonstrate experimentally that the Earth revolves around itself with an angular velocity Ω, in a period of 23 hours, 56 minutes and 4 seconds.
Thus, Foucault knew that the longer the string attached to the weight, the slower the swing of his pendulum. He could attach the string above to an almost frictionless pin, and if he used a very large weight, the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.
