Because the small area of that desert provides the provisions the organism needs. They adapt to their climate, so as long as the desert keeps its supply, the organism will stay
<span>because “Barrow is ground zero for climate-change science, and because we worry that climate change is shrinking the sea ice and we don’t know how that will affect the animals that depend on it. But at this time there is no effective plan if a catastrophe such as a ship collision or oil spill occurs. The Coast Guard hasn’t decided what its presence will be in the Arctic. Someone needs to monitor whats going on there.</span>
1. The right answer is in a discontinuous manner.
During DNA replication, the DNA polymerase synthesizes complementary DNA by mating on both strands, since the two strands are antiparallel, the replication is bidirectional, which means that one of the two strand is synthesized in a direction opposite to that of the direction of the enzyme, to do this, the DNA polymerase is obliged to synthesize DNA in the form of small fragments which are called Okazaki fragments, and its synthesized discontinuously (these fragments are not glued together by phosphodiester liasons, it is only after that another enzyme will intervene to ligate these fragments (DNA ligase).
Evolution maybe?
Hope this helped
