The start signal is AUG which codes fo methionine. The amino acid sequence will be as follows: <span>Met-Phe-Pro-Ser-Tyr-Pro-Lys-Asp-Lys-Lys-Glu. The first codon (GCC) codes for alanine but not in the amino acid sequence because it is not a start codon (the only start codon is AUG which codes for methionine).

C. Organize it into charts, graphs, do calculation if necessary.
Spread of disease is density dependent because it is more severe the greater the population density as the disease would spread more easily. If there is low population density it would spread slower.
Because you cannot test it or observe it.
A scientific theory are created through the scientific method, in the scientific method you need to be able observe it and experiment.
