The pyloric valve control food movement from the stomach into the small intestine.
Energy changes forms from heat, to kenetic, to potential energy. However, the total energy is the atmosphere is conserved, meaning energy can only change forms, but cannot be produced.
The answer is anticodon.
Anticodons are base triplets on transfer RNA (tRNA). t<span>RNA carries amino acids to the ribosome for protein synthesis. </span>The prefix<em> anti-</em> suggests that anticodons are complementary to the codons on mRNA. Codons are base triplets on mRNA. So, anticodons of tRNA pair with codons of mRNA in the process of protein synthesis.
