This question is incomplete. Here's the complete question.
Which would be an adaptation for living in the tundra?
funnel shaped leaves to help water runoff
deep roots to go into the permafrost
hibernation to lower metabolism in the winter
large ears to release heat
Answer: hibernation to lower metabolism in the winter
Explanation:
Hibernation is something many animals do to survive in the tundra. They hid in dens for several months during the winter. Their metabolisms get to a dormant state in which their bodies survive thanks to stores of fat gained during the summer. The Grizzly bear is an example of a tundra animal that hibernates during the winter.

It's true, Venezuela is the biggest supplier of oil to the U.S, also other countries like Saudi Arabia, Canada, Nigeria and Mexico.
Answer:
The passenger aircraft would take 10.542 years to reach the Sun from the Earth.
The passenger aircraft would take
years to reach the gallactic center.
Explanation:
The distance to the sun from the Earth is approximately equal to
, if the passenger travels at constant speed, then the time needed to reach the sun is calculated by the following kinematic formula:
(1)
Where:
- Travelled distance, measured in kilometers.
- Speed of the passenger aircraft, measured in kilometers per second.
- Travelling time, measured in seconds.
If we know that
and
, then the travelling time is:




The passenger aircraft would take 10.542 years to reach the Sun from the Earth.
The distance between the Earth and the galactic center is approximately equal to
. If the passenger travels at constant speed and if we know that
and
, then the travelling time is:




The passenger aircraft would take
years to reach the gallactic center.
