Why does antarctica recive less of the suns heat then panama

The curve of Earth's surface means that solar waves hit Earth at different angles. Panama is located near the equator and receives more direct rays and more heat than Antarctica which is located near the south pole.

A) alveoli

Explanation:

Bronchioles are part of the respiratory system by which air passes from the nose  to the alveoli (air sacs). They are divided  into smaller terminal bronchioles which are  the conducting zone (involved in respiration) and these then divide into the smaller respiratory bronchioles - the beginning of the respiratory region. Terminal bronchioles are the most distant segment of bronchioles which divide to form respiratory bronchioles which contain a small number of alveoli.
