DNA double helix is made of 2 complementary DNA strands . These strands are held together by hydrogen bonding between the complementary bases on each strand.
Nucleotides are the building units of nucleic acids. Bases are components of the nucleotides.
Bases on one DNA strands pairs with bases on the complementary DNA strand through hydrogen bonds.
bases can pair with the complementary base.
Complementary base of thymine is adenine .
Therefore thymine pairs with adenine.
The Arctic Fox lives in the Arctic Tundra (more or less around Alaska, Iceland I think, and other places like that). During the winter, their fur is very thick and solid white (not always SOLID but generally speaking). During the summer and spring, their fur turns brown.
1. Of course, during the winter in those regions, it's going to be snowing and ice is going to be all over the ground. By having a white coat, they're able to blend in and hide from predators, such as the Arctic Wolf and Polar Bears. By turning brown, they'll be able to blend in with the dirt after the snow and ice melts, and again, hide from predators. For the other fox, their brown coat blends in with the dirt, trees, dead leaves, etc. and they'll be able to hide from prey and predators alike.
2. The Arctic Fox also has very thick fur during the winter, which allows it to survive the extreme temperatures. They also dig burrows in the snow for shelter in blizzards. This gives them the ability to survive natural disasters (at least one of them).
I can't think of a third one but these should give you a pretty good idea of how their adaptations help them survive. I really love the Arctic fox so I know quite a bit about them. I really hope this helps you.

Answer:
Fat is hydrophobic and it repels water due to the polarity of the fat molecules. Fat will not dissolve in water but some water can dissolve in much fat. And some fat can dissolve in much water.
