Where are the strongest jet streams located?

The correct answer is far away from the equator.  

Explanation:

The formation of jet streams takes place due to enormous bodies of air. The polar jets are the strongest of the jet streams, they are situated at high altitudes, that is, about 30000 to 39000 feet above the level of the sea. There are southern and northern polar jet streams.  

The northern streams are found in Europe, North America, and Asia, while the southern streams are mostly confined to Antarctica. The jet streams are stronger at the time of winters, as these are the bodies of fast-moving air, which can turn into threatful typhoons and cyclones.  

cell regulation is conducted by special proteins.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
