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 Axis of Power Usually there is known to be three main countries in the Axis Powers. Germany, Italy and Japan are the major three they are also known as the Tri Axis.However there are more countries in the Axis Powers then just those three, there is Austria-Hungary, Romania, and Bulgaria among others.he Axis Powers, is just the title Germany and those allied with Germany gave themselves for World War Two, just like in World War One they were known as the Central Powers although in World War One these were not all the same countries allied with Germany. Hope this helps!
