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.

I would say false, because to find the ABSOLUTE age of a rock, scientists have to preform radioactive dating.
I hope this helped! :-)

The correct answer is B. Possible side effects of a new medical treatment or product.
Explanation
A side effect is a concept that refers to the effect that a drug or treatment produces on the patient. Generally, when a drug is produced, a clinical trial is necessary to prove its effectiveness. This requires the participation of several volunteers who will test the drug and verify its effectiveness. However, these clinical trials have risks for volunteers since they can bring them negative effects because they are going to test drugs that have never been used before, so they must give their consent through a document called "informed consent. "where the volunteer is informed about the possible risks that the clinical study may have on him and if he is willing to undergo the test. Therefore, one of the main topics discussed during an informed consent is the possible side effects that the clinical study can bring to inform the volunteer of these conditions and confirm that he agrees with them. Therefore, the correct answer is B. Possible side effects of a new medical treatment or product
Answer:
The Correct answer is 50%
Explanation:
The gametes produces are T, T by 1st parent and T, S by 2nd parent
T T
T TT (tall) TT (tall)
S ST (medium) ST (medium)
So, the fraction of giraffes that are tall = 
= 0.5×100% = 50%
So, The Correct answer is 50%
