The amount of the α-Fetoprotein gets increased in amniotic fluid at the time of neural tube defects. The maturity of lungs is not easily determined by the 35 weeks gestation. The amniocentesis cannot be used for the detection of diabetes and cardiac disorders.
Thus, the answer is neural tube defect.
The living factors in an ecosystem are called the biotic factors.
