Tundra can be found on the tops of some mountains.
Dense fat, with thick fur that covers all external surfaces
Special bones in their nose that help them save water
Keeping their extremities relatively cold
All of the above
Some plants of the tundra can perform photosynthesis at lower than normal light levels.
What happens to plants when they freeze
Permanent frost
Any frozen soil
Soil that stays frozen for two or more years
The cold causes fur to change colors
The changing fur has no real purpose
Shedding one color coat for another helps them stay camouflaged in most seasons
The animals try to keep up with the newest styles
