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:
It has adapted to feed on available food
Explanation:
The apples from Washington state traveled fewer kilometers.
Buying apples from Washington improves the quality of air better than buying apples from Chile
Explanation:
Washington state is a state in the United States where the Boston market is located. Both the market and the producing farm are within the same country.
Chile is a country in South America. The country is located south of United States of America in another continent.
The distance between Chile and the Boston market is farther compared to the local distance between Washington state and Boston market.
Buying apples from Washington will improve the quality of air. What conditions the quality of air in a particular region is the amount of materials released to the environment. In importing the apples from Chile, ships conveying them or airplanes as the case may be will use up more fossil fuels and contribute the anthropogenic release of greenhouse gases.
In transporting the apples from Washington to Boston, lesser fuels are used and the greenhouse gases released are lower.

Answer:
In order to change any part of the cell theory, we will have to prove that the cells are not the basic unit of life. We will have to provide evidence that a cell does not distinguish a living thing from a non-living thing. We will either have to prove the spontaneous generation to be true or have to prove that if not cells, then what are the basic units of life. We will also need evidence to prove that a cell does not arise from a pre-existing cell.
