Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
Answer:
The first graph is the correct one.
Explanation:
The first graph shows a bell-shaped curve. This type of curve is used in results that present a normal distribution of variables, where the conclusive values are grouped around an average. This makes this type of graph ideal for representing data that shows that four-year-olds score higher on a self-control assessment related to how much longer they listened to classical music while reading. This is because these data are grouped around an average that allows this type of conclusion to be taken.
The parts of the moon that are elevated and made up of jagged rocks are called the Lunar Highlands. These are actually the light-colored parts of the moon that we can see from Earth. These parts are made up of mountains. The darker parts that we see from Earth are the craters. The Highlands make up most of the near side of the moon (the part we can see). On the other side of the moon, called the far side, it is made up mostly of Islands, parts of the moon that are wide and said to be once covered in water.

The air
Explanation:
the air has a component of 79% of nitrogen gas (N2)
