The nitrogen fixation is a very important process because it is the principal source of nitrogen in the marine environment for photosynthetic plants. Nitrogen is a growth limiting nutrient, that is very important for the growth of photosynthetic plants. During the process of nitrogen fixation, nitrogen is absorbed from the atmosphere and it is fixed by nitrogen fixing organisms.
The answer is <span>C.silent.
Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.

Answer:
According to me answer no 4 is correct.
Explanation:
single cell amoebas can perform all life functions capture the food, digestion, respiration, excretion, and reproduction also. These all are similar to multicellular animals.
Answer:
Protein/enzyme synthesis
Explanation:
<em>The process of synthesis of protein in the cell is mainly responsible for the increase in the protein content of the cell.</em>
<em>The process which is also known as the translation process of gene expression takes place at the G1 and G2 phases of the interphase of the cell cycle.</em>
During protein synthesis, mRNA synthesized in the nucleus are transported to the cytoplasm and the genetic codes on the mRNA are translated into their respective amino acids linked together by polypeptide bonds. The protein are then folded in specific ways for specific enzymes.
The new species come from old ancestors of the animals that were there, over time they slowly evolved, and they adapted to that new environment.
