Answer:

The 5' end has free phosphate group while the 3' end has free OH group.

Explanation:

Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.

Darya [45]

Since the speed of many physiological processes in marine organisms is determined by the temperature, the first consequence of the changes in the conditions of the medium becomes offset the timing of seasonal events, such as the timing of spawning fish. There have also offset migration routes and spawning areas. So, as a result of warming in the Sea of ​​Japan, spawning navaga shifted to an earlier date, because of the reduction of the area of ​​"cold spots" in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab are lengthened, but because of the temperature rise to the east of Japan, spawning saury expanding. These changes significantly affect the success of reproduction, resulting in changes populations of their fishery.
