Vitamin A helps form and maintain healthy teeth, bones, soft tissue, mucus membranes, and skin. Vitamin B6 is also called pyridoxine. Vitamin B6 helps form red blood cells and maintain brain function. This vitamin also plays an important role in the proteins that are part of many chemical reactions in the body.
Elevation can affect the amount of sunlight that plants receive, the amount of water that plants can absorb and the nutrients that are available in the soil. As a result, certain plants grow very well in high elevations, whereas others can only grow in middle or lower elevations.
For the answer to the question above, I think the answer is "will lack A and B red blood cell antigens"
Type O blood is lacking of some of the antigens that the A & B blood cells have. Hope this helps
