Answer:
- The following adaptations are made by these animals to survive in cold climates
Polar bears have blubber, a thick layer of fat under their skin to keep them warm. Their white fur provides insulation against cold and helps to hide from their prey to be able to hunt on land and in water. Female polar bears hibernate in the den during worst winter and cubs are also born there.
Arctic foxes have large furry paws that act as snow shoes that help them to move easily in the snow. Their furry and ears help to protect from cold.

a) The polar bear
thick layers of fat and fur - for insulation against the cold. a small surface area to volume ratio - to minimise heat loss. a greasy coat that sheds water after swimming - to help reduce heat loss. large feet - to distribute their load and increase grip on the ice.
b) Arctic fox
Arctic foxes have several adaptations that allow them to survive. there round, contact bodies minimise surface area that is exposed to the cold air. their muzzle,ears, on legs are short, which also conserves heat.. process also have thick fore on their paws, which allows them to walk on both snow and ice.
