Because freezing will often burst the cell walls and destroy tissue. The crystals of ice are very sharp and hard to control AFAIK. Note what happens to a banana or many types of fruit after you dethaw — it becomes all mushy and not of the same structure, fiber and cell form as before, like a bad beam up in Star Trek.
Answer:
See the answer below
Explanation:
<em>An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.</em>
<u>Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons. </u>
The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.
Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

If it helps, the answer is Mutualism (let me know if it is for some reason incorrect)
