Answer:

Explanation:
Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

<span>Human sweat is a result of our body getting over heated. We sweat through our pores so our temperatures don't go up and as a result we stay at a normal temperature. We may feel hot but that's because we are hot from the heat of something. If we didn't sweat then our temperature would become very high and we would die.</span>
