If the ambient temperature is very hot like in the Sonora Desert in summer like say 45 Degrees Celsius then the rate of body cooling will be slow and the body will heat up significantly though perspiring will help a little to cool the body. If the ambient temperature is like -40 degrees celsius, then the body will cool off very rapidly and warm clothes that cover most of skin will be required to prevent frostbite.
<span>Another valine would be added to a protein sequence in lieu of the lysine. A point mutation will happen in the protein, but would not change all lysines to valines, as there are multiple codons for lysine, and multiple tRNAs which carry it, and assume that this accident only happened to one of the lysine tRNAs.</span>
