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
All elements are made of "atoms", and an atom is made up from 3 basic particles: Electrons are particles with a negative charge :)
Answer:
The answer is ectoderm. The mesoderm is the middle layer of lining. The endoderm is the innermost layer. You can remember it by:
Endo/ sounds like inner
Meso/ M for middle
Ecto/ sounds like exo, bugs have exoskeletons that are on the outside.

I honestly don’t know but I believe it’s A
