I believe that a 'dynamic low' is produced by The strong rise of air.
A dynamic low develops if the air flow converges in lower regions of the atmosphere and diverges in altitude while the air is kept up in the center of the low. A low pressure area is a region on the topographic map where the atmospheric pressure is lower than that surrounding locations. Low pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere.
This
reserve is home to terrestrial and marine mammals, including grizzly
and polar bears, caribou, wolves, and wolverine as well as beluga and

Answer:they won't for a pair
Explanation:Basically it all depends on process called complementary base pairing, the structure of thymine and adenine is such that it forms two hydrogen bonds and therefore pair up
2.guanine and cytosine have such structure that they form three hydrogen bonds and pair up
So Adenine complements only thymine and guanine complements cytosine and there aren't any chances of guanine pairing up with thymine.
