Adaptations and Insulation in Animals

The video explores how polar animals adapt to extreme cold. It covers migration, insulation through fur and blubber, and unique adaptations like penguin waterproofing and countercurrent heat exchange. Hibernation and camouflage are also discussed as survival strategies.

Why do animals migrate to warmer climates during winter?

• To avoid predators

• To find new mates

• To explore new territories

• To escape harsh weather and find food

What is the primary function of a polar bear's fluffy white fur?

• To help them swim faster

• To trap dry, warm air next to their skin

• To make them look larger

• To camouflage in the snow

What unique feature do polar bear guard hairs have?

• They are hollow and transparent

• They are very short

• They are colored black

• They are waterproof

What is blubber primarily composed of?

• Proteins

• Minerals

• Carbohydrates

• Lipids

Why is blubber an effective insulator?

• It is made of water

• It has low thermal conductivity

• It has high thermal conductivity

• It is very thin

How do penguins keep their feet from freezing?

• By constantly moving

• By growing extra feathers

• By staying out of the water

• By using countercurrent heat exchange

What do penguins use to waterproof their feathers?

• Oil from a gland near their tail

• Water

• Mud

• Snow

What happens to an animal's heart rate during hibernation?

• It stops

• It increases

• It stays the same

• It slows down significantly

How do small mammals like Tundra Voles survive the winter if they can't hibernate?

• By migrating

• By using the snow to insulate their tunnels and nests

• By staying awake all winter

• By growing thicker fur

What adaptation helps the Snowshoe hare move through deep snow?

• Very wide hind feet

• Sharp claws

• Long ears

• Thick fur
