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.
Answer:
b. flat rotation curves in spiral galaxies
Explanation:
Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.
Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.
The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.
Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
Description The Fermi paradox, named after Italian-American physicist Enrico Fermi, is the apparent contradiction between the lack of evidence for extraterrestrial civilizations and various high estimates for their probability. Michael H. Hart formalized the basic points of the argument in a 1975 paper.
