Each hemoglobin molecule is made of four subunits, each containing a heme group that can bind one molecule of oxygen. Therefore, one molecule of hemoglobin can bind four molecules of oxygen. Oxyhemoglobin is hemoglobin bound by oxygen, and it gives oxygen-rich blood a red color.ach hemoglobin molecule is made of four subunits, each containing a heme group that can bind one molecule of oxygen.

Hitler referred to Germany under his regime as the Third Reich. He wanted to create a new government that would rule Europe for 1000 years.  The Axis was the alliance of 3 countries, Germany, Italy and Japan, that fought against the Allies. Other countries also joined or were forced to join the Axis.
The Allies would govern Germany through four occupation zones, one for each of the Four Powers--the United States, Britain, France, and the Soviet Union. The establishment of zones of occupation had been decided at a series of conferences.
