The cardiac muscle has intercalated disk that allows rapid transmission of the impulse. This will allow the cardiac muscle to have a coordinated way. The heart muscle has pacemaker that will spread the signal in regular time. The transmission of impulse is also controlled by a few checkpoint like the bundle of his to make the signal to the Purkinje fiber of left and right ventricle at the same time.
This particular organism lives in an environment that is rich in organic material, particularly amino acids and proteins. Also the organism has low amount of amino acid biosynthesizing genes and relatively higher amount of peptide transporters.
In the model, a codon is identified as part of the mRNA strand. A codon is a series of three nucleotides on mRNA that codes for an amino acid.
mRNA
This is one form of RNA that serves as a template for protein synthesis. It is transcribed from DNA and then translated at ribosomes to produce a protein.
Explanation:First of all skin color is determined by how much melanin you have and the one thing that would show more variability in the human population is probably the one that uses less genes, because of how we come from only two genes which makes us different.
