Answer:
Neural tube defect.
Explanation:
Amniocentesis may be defined as the medical procedure that are used for the prenatal diagnosis of the chromosomal abnormalities and genetic defects. The sex of a baby can also be determined by this technique.
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.
Answer:
Three primary components of axial skeleton are skull, vertebral column and ribs.
Explanation:
Axial skeleton forms the central axis f the body. Three primary component of axial skeleton are:
Skull: Skull protects the brain and supports the face structure. Twenty two bones are present in the skull. Two main categories of skull bone are cranial bone and facial bone.
Vertebral column: Vertebral columns support and protects the spinal cord. The vertebral column serves as the attachment site for the muscles and neck.
Ribs cage: Ribs cage is also known as thoracic cage and includes the structure of sternum, ribs, coastal cartilage and thoracic cartilage. Ribs consists of twelve bones.
Answer:
These are classified as the Main Sequence Stars.

Answer:
D. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.
Explanation:
If we assume that one gene is involved in Ellis-van Creveld syndrome and we name that gene with A, then the genotype of the syndrome would be aa.
In population 1, the frequency of the syndrome is 1/150000=0.0000066(it is the frequency of the aa gentotype)
In population 2, the frequency of the syndrome is 1/500=0.002
According to Hardy-Weinberg equilibrium
p2+2pq+q2=1 (p2 is the frequency of the dominant homozygous, 2pq is the frequency of heterozygous and q2 is the frequency of the recessive homozygous).
q or the frequency of the Ellis-van Creveld allele in Population 1 is 
=0.0026
q or the frequency of the Ellis-van Creveld allele in Population 2 is 
= 0.0447
