A polar body is a small haploid cell that is formed concomitantly as an egg cell during oogenesis, but which generally does not have the ability to be fertilized.When certain diploid cells in animals undergo cytokinesis after meiosis to produce egg cells, they sometimes divide unevenly.herefore, the formation of the first polar body is an especially important factor in forming a healthy zygote. However, chromosomally abnormal polar bodies are not guaranteed to induce the development of an abnormal zygote.
A polar bear's stomach can hold an estimated 15% to 20% of its body weight. A polar bear generally eats this much only when its energy demands are high. A bear can assimilate 84% of the protein and 97% of the fat it eats. Polar bears need an average of 2 kg (4.4 lb.) of fat per day to obtain enough energy to survive. A ringed seal weighing 55 kg (121 lb.) could provide up to eight days of energy for a polar bear. Hibernating polar bears do not eat.
