Leokris [45]
I would say the answer is either A or B, the Law of Consevation of Energy states that,"<span>the total energy of an isolated system remains constant</span>" so this energy isn't destroyed, it's simply useless.

Luda [366]

Answer:

substitution, missense mutation, and transition

Explanation:

A mutation is any change in the genetic information of an organism. A substitution is a point mutation by which a single nucleotide base pair is replaced by a different nucleotide. Moreover, a missense mutation is a point mutation that results in the incorporation of a different amino acid in the polypeptide chain since this mutation generates a new codon which codes for a different amino acid. Finally, a transition is a point mutation where a purine (either Adenine or Guanine) is changed to another purine, or a pyrimidine (either Thymine or Cytosine) is changed to another pyrimidine (in this case, Cytosine is changed to Thymine).
