What is the characteristic of polar?
Characteristics of polar areas include: Climate – long cold winters, with annual temperatures mostly below freezing. Polar areas are often windy, with very little precipitation.
What characteristics does a polar bear have to survive?
Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. Two coats of fur and a thick layer of blubber help insulate the polar bear’s body from the cold, keeping its temperature at an even 37° C (98.6° F).
What characteristics are common to animals who live in the polar regions?
Some ways that animals in polar habitats stay warm are:
- Developing a thick layer of fat that keeps them cosy.
- Having thick fur all over their body and feet.
- Having thick layers of feathers.
- Burrowing into the ground or into snowbanks (like igloos! )
- Migrating south during the coldest months.
What do you know about polar animals?
The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore.
How do you determine if something is polar or nonpolar?
(If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.) If there are no polar bonds, the molecule is nonpolar.
What is polar and non-polar?
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Where do polar animals live?
the Arctic
Polar bears live in the Arctic, on ice-covered waters. Polar bears rely on sea ice to access the seals that are their primary source of food, as well as to rest and breed. The total polar bear population is divided into 19 units or subpopulations. Sixty percent of the sub-populations are in Canada.
What are the characteristics of a polar bear?

What kind of animals live in the polar biome?
Some of those animals in a Polar Biome include: Arctic Fox, Polar Bear, Arctic Hare, Killer Whale, Arctic Wolf and the Snow Owl. The same goes with plants as it did with the animals. Except plants can’t survive and live in a Polar Biome. It is all too cold, and there is no soil for the plants to root in anyways.
What kind of teeth does a polar bear have?
Polar bears have 42 teeth, which they use for catching food and for aggressive behavior. Polar bears use their incisors to shear off pieces of blubber and flesh. Canine teeth grasp prey and tear tough hides. Jagged premolars and molars tear and chew.
How big does an adult polar bear get?
Polar bears use their claws to catch and hold prey and to gain traction on ice. Polar bear paws are ideal for roaming the Arctic. Adult males normally weight 350 to more than 600 kilograms (775 to more than 1,300 pounds). Adult females are smaller, normally weighing 150 to 290 kilograms (330 to 650 pounds).

How are animals adapted to live in the polar regions?
Polar animals have evolved to survive life in the deep cold. Some animals, such as birds and whales, migrate long distances each summer, drawn by the abundant food supply or ideal nesting grounds in the Arctic.

What kind of animals live in the north polar region?
The animals of the north polar region can be seasonal visitors at the edge, permanent residents of the High Arctic or anywhere in-between.
