Eukaryotes are larger cells with membrane-bounded organelles.
Prokarotes are not that large and do not have a nucleus or any memberane-bound organelles.
So there are four types of mountains and these are fault block mountains, fold and thrust mountains, unwarped or dome mountains and volcanic mountains.
Based on the given locations above, the Sierra Nevada mountains of California are fault block mountains. The Alps of Europe is an example of a fold and thrust mountain. The Black Hills of South Dakota and Teton range of Wyoming are unwarped or dome mountains. Hope this answer helps.
Answer:
Every winter, Arctic sea ice grows around the pole, its frozen tendrils threading along northern coasts. Right now sea ice has just passed its peak coverage for the year, and will begin to shrink with the coming of spring. It’s a crucial time for polar bears, whose food supply is inextricably linked to sea ice.
And in recent decades, sea ice has been shrinking faster than ever. According to the National Snow and Ice Data Center, 2019 has the seventh-lowest sea ice cover in the Arctic since they began collecting satellite data 40 years ago.
This year “doesn't break any records, but it's the trend that matters,” says University of Alberta polar bear scientist Andrew Derocher. “The downward trend in Arctic sea ice across all months is the concern,” he says, and “now we wait to see what spring conditions bring.” (Read more about global warming’s link to polar bears.)
A cold spring allows ice to linger, giving polar bears easier access to one of their favorite foods: seals. A warm spring cuts short the availability of their food super-highway....
