saw5 [17]
The main factor that controls the rate of breathing is..
A.) concentration of carbon dioxide. 

If we think about it.. When we breath in oxygen, right away it enters your lungs and turns into carbon dioxide. Well since your lungs need to process oxygen and bring oxygen into the blood stream. Then as soon as the oxygen comes inside (inhale) the oxygen turns into carbon dioxide and you breath it out (exhale) to get a new oxygen load. 

Makes sense? lol

Good Luck! :)

klasskru [66]

Answer:

Explanation:

    Folic acid (folate) is a complex B vitamin. Along with vitamin B12, folic acid is required for the formation of normal red blood cells and for the synthesis of DNA (deoxyribonucleic acid), the genetic material of cells. Folic acid is also necessary for the normal development of the fetal nervous system.

  Pregnant women or women of childbearing age should take folic acid supplements to reduce the risk of having a baby with a birth defect, especially neural tube defects. The folate serves to ensure a healthy pregnancy and good development of the baby. If a pregnant woman has folic acid deficiency, there is an increased risk of having a baby with a congenital spinal cord or brain defect (neural tube defect).
