Answer:

The most important are the lungs, more precisely the alveoli.

Explanation:

Alveoli are structures of the lungs where gas exchange occurs. They allow oxygen from the air to pass into blood. Oxygen diffuses through the walls of alveoli into the capillaries that surround it. Oxygen is then bonded with the iron in red blood cells and travels to the heart. The heart then sends the oxygenated blood out to all the cells in the body.

The ___ biome is characterized by moderate temperatures and high quantities of precipitation.
diamong [38]

Answer:

The temperate rain forest.

Explanation:

Temperate rain forests are similar in structure and precipitation amounts to a tropical rain forest. The difference is in the location and temperature of each. Tropical rain forests are located on and near the equator, and are incredibly warm and humid, with large amounts of precipitation. Temperate rain forests are found north of the Tropic of Cancer and have moderate temperature and humidity levels. The way to remember the difference is to notice that Temperate is a combination of 'moderate' and 'temperature' and can be said to mean "moderate temperature". I hope this is the answer you were looking for!
