Based on the 20 amino acids found in proteins, there are 6840 possible variations in a polymer composed of just three amino acids.
<h3>What are amino acids?</h3>
Amino acids are the molecules from which protein molecules are made from.
There are 20 common amino acids from which protein molecules are built up from.
The amino acids are joined one to another in the protein by peptide bonds.
In a polymer composed of three amino acids, the possible variations are calculated by permutation.
The possible variations are 20 permutation 3.
nPr = n!/(n - r)!
where n = 20 r = 3
nPr = 20!/(20 - 3)!
nPr = 6840
Therefore, there are 6840 possible variations in a polymer composed of just three amino acids.

An echinoderm uses its tube feet for attachment and feeding.
Explanation:
- Tube feets are usually considered as locomotory organ of Echinoderm.
- They have tube feets arranged around their oral groove.
- These tube feed help the organism to push the food into the oral groove.
- Tube feets also help the echinoderms to attach themselves to the floor of the ocean and locomote slowly in a sliding manner.
