Maintaining the genetic diversity is long term solution which help to maintain polar bear population.
Explanation:
Polar bear from Norwegian way bears are genetically unique. These bears are only who survive in the world. they have lack genetic diversity so it is possible to they stay healthy and somehow survive in worst condition.
The climate and condition of Norwegian is way better so it is necessary to relocate the other polar bear. The other important thing is to ensure about their food. Polar bear mainly eat seal but due to the melting of ice they are unable to get proper food.

Answer:
The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Explanation:
In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.
In purine nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.
In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.

Answer:
The population is decrasing
Explanation:
As we can see from the chart, the diversity of animals in Africa are being affected year after year. In 10 year gap 53,000 lions, 42,500 cheetahs and 12,500 zebras are dead and this is a dangerous sign.
