A tadpole is pretty much a baby frog and a frog is grown up.
The nucleotide triplet that encodes an amino acid<span> is called a </span>codon. Each group ofthree<span> nucleotides encodes one </span>amino acid<span>. Since there are 64 combinations of 4 nucleotides taken </span>three<span> at a time and only 20 </span>amino acids<span>, the code is degenerate (more than one </span>codon<span> per </span>amino acid<span>, in most cases).</span>
Option C - They show that the number of atoms of each element is the same in the products and reactants.
The conservation of mass essentially states that no matter can be created or destroyed. It is because of the conservation of mass that we have to balance chemical equations in order to ensure than no atoms are destroyed or created.
-T.B.
Speed of light is usually time and space so probably C
