Answer:
<em>Scientists should repeat quantitative experiments so they are 100% percent confident in their results. Without repeating the experiments, you could have a problem, and not realize you have a problem, because you didn't repeat your experiment.</em>

Pericardium is a membrane that surrounds the heart and the roots of the blood vessels. It is composed of two layers: the serous layer and the fibrous layer.
The Pericardium keeps the heart in place and in proper working order. Any disorders that occurs in the pericardium will also affect how the heart works.
Inflammation of the pericardium may be a result of infection, heart attack, heart surgery, and other medical side effects.
Answer:
a) phenylalanine
Explanation:
A triplet codon results into a particular amino acid. mRNA is read in 5' to 3' direction during translation. tRNA carrying an amino acid enters the A site first. Then a peptide bond is formed between the new and old amino acid. The polypeptide along with the tRNA moves to P site while the now empty old tRNA moves from P to E site and exits. Hence a tRNA is first in A site followed by P site and then finally E site.
Here, a tRNA with histidine amino acid is present in the P site. From the given sequence, only CAU codon can result into histidine. So if CAU region is present in P site that means that UUU will be present in A site. UUU codes for phenylalanine amino acid so the tRNA entering the A site will carry phenylalanine.
There are many types of mutations. Due to some properties of the DNA, some mutations can be harmless, some can change the function of a cell. A cancerous cell is a cell that don't stop to be made because of a malfuntion of the DNA or a chimical factor.<span>
