I think The upper midwest is the best choice.
It is 10 latitude 45 and longitude
latitude and longitude helps you if you are lost and you see a map lets say you were on the phone with 911 and they asked you were you are.That is when you wold say oh i am at 45 longitude and 10 latitude.
The answer to this question is D.
Climate change is causing the Earth to gradually increase in temperature, this is causing the warming waters.
Coral has this beneficial relationship with this algae called zooxanthellae. The coral provides a home where the algae provides some nutrients. Zooxanthellae uses photosynthesis to get its own food (It's not getting any inside a coral polyp!)
When there is an increased amount of sunlight there is more photosynthesis occuring, which means more and more algae.
To disprove C, the great barrier reef is KNOWN for its biodiversity. Theres LOTS goin' on down there.
Hope this helps!
