<span> answer: poor regulation of the brain's locus </span><span>ceruleus may lead to panic attacks</span>.
Locus ceruleus is a nucleus in the pons involved with physiological responses to stress and panic. When there is stress he responds by increasing norepinephrine (NE) secretion, which is a critical
regulator of numerous activities from stress response. Panic attacks result from alterations to NE.

Type of break is cervical and lumbar curvatures.
If there are no ossification centers, there are no osteoblasts, no osteocytes, no spongy bone, which in turn means no compact bone thus no flat bones which serves as a protection layer.
Osteoclasts are large bone cells with up to 50 nuclei. They remove bone structure by releasing lysosomal enzymes and acids that dissolve the bony matrix. Intramembranous ossification directly converts the mesenchymal tissue to bone and forms the flat bones of the skull, clavicle, and most of the cranial bones. While bone resorption is performed by large immune cells called osteoclasts, osteoblasts, a type of specialized connective tissue-related cells, is responsible for making new bone.

Answer:
A. VG = 80
B. Broad sense heritability = 0.80
C. Narrow sense heritability = 0.30
D. Average yield = 430 Units
Explanation:
A. Given that
VA = 30
VD = 50
VI = assumed not available
Therefore
Total genetic variance (VG) = VA + VD
= 30 + 50
= 80
VG = 80
B. Given that
VP = 100
VG = 80
Broad sense heritability, H2 = VG/VP
= 80/100
= 0.80
C. Given that
VA = 30
VP = 100
Narrow sense heritability, h2 = VA/VP
=30/100
= 0.30
D. The difference in selection = 500 - 400
= 100
Recall,
Selection response is heritability multiplied by selection differential.
That is
R = h2S
Selection differential = 100
Heritability h2 = 0.30
Selection response = 0.30 × 100
= 30units
Therefore, expected average yield = 400 + 30
= 430 Units
