GAU to GAC is least likely to change phenotype of an organism.
<h3><u>Explanation</u>:</h3>
Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.
Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.
Both the GAU and GAC codes for aspartic acid. So the phenotype won't be affected much by this mutation
Answer: Coral reefs are important to the ecosystem because they are the pillars on which marine and coastal ecosystems are built. They keep plants, fish, and animals fed. They clean up our water and protect our coasts.

Answer:
The use of music
Explanation:
<em>The independent variable in the example is the use of music.</em>
The independent variable in research or experiment is a variable whose value is not affected by any other variable. That is, the value of an independent variable is not influenced by any other variable.
<u>In this case, the use of music stands alone and is not influenced by any other variable in the experiment. In actual fact, the use of music's effect is being tested in the experiment and hence, is not in itself influenced by any other variable.</u>
Answer:
telophase
Explanation:
Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.
