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.

Answer:
Small Intestine
Explanation: After the stomach in the alimentary canal comes the small intestine.
Answer:
the answer is " POPULATION".
Explanation:
A population is a group of individuals of same species living and inhabiting the same environment. in other words : All the inhabitants of a particular space forms a population in which the species interbreed.
so the correct answer is POPULATION.
Answer: The charges of the objects are A: Positive and B: Negative.
Explanation-
The electric field lines are pictorial representation of the electric field in terms of imaginary lines.
The direction of electric field is away from the positive charge and is directed towards the negative charge.
In this question, the electric field lines are emerging from A and coming towards B.
Thus, the right answer is A: Positive and B: Negative.
Answer:
true
Explanation:
Embryonic stem cells.
These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
