<span>Erwin Chargaff's research found that there are two pairs of nucleotides in the DNA molecule, adenine-thymine, and guanine-cytosine. Those two pairs of nucleotides are complementary and since they pair up in the DNA molecule, the amount of one nucleotide in the pair must be equal to the amount of the other nucleotide of the pair. He also found that different species have different proportions of nucleotides, which proved that DNA is the carrier of genetic information, not the proteins.</span>
Answer: They store energy because they may need it for winter. Take pine trees for example. They are fine through the winter because they have stored enough energy to keep their leaves. this works with regular trees to. The reason why trees don’t die in winter is because they store energy to last.

It could be concluded from their reluctance that they will eat only their normal diet rather than something they have never eaten before.
