The musk ox has a large body size and small appendages. How do these characteristics enable it to survive in the tundra?
The large body size and small appendages of the musk ox help minimize its heat loss. The smaller the surface area of an animal compared to its weight, the more slowly it loses heat. The musk ox has a large weight relative to its surface area.
How does the Alaska blackfish survive in waters with temperatures of 5ºF?
The Alaska blackfish survives in water with temperatures of 5ºF by producing chemicals that lower the freezing temperature of cellular fluids. This keeps the fluids of the fish from freezing, allowing it to survive.
Explain how the woolly lousewort has adapted to the cold climate of the tundra?
The woolly lousewort has dense hairs that surround its flowers. These hairs trap the heat from the sun and allow its temperature to be maintined, keeping the flower at a warm enough temperature for it to germinate its seeds.
Why is there limited vegetation in the tundra?
The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.
Why are plants and animals able to survive in the tundra?
Plants and animals have developed specific adaptations that allow them to survive the extreme climate of the tundra. These adaptations include thick fur, dense hair, retention of dead leaves, and feathered feet.
