Answer with Explanation:
This kind of "muscular dystrophy" is brought about by<em> "spontaneous mutation."</em> This means that the genes of Tracie's first born child mutated for no apparent reason. The mutation affected the function of the cells, thereby causing the disease.
It could also be that both Tracie and her husband (or probably one of them) has such a <em>recessive condition.</em> This means that the gene mutation wasn't apparent for them or for many generations, but it became apparent in their child when the child inherited the mutated gene.
Most of the time, muscular dystrophy is passed from generation to generation or is heritable. The case of Tracie's child is just one of the rare cases of "spontaneous mutation."
Thus, this explains the answer.
When the air is inhaled via the nose, it will go into the nasal passage, through the sinuses. It will then travel down the larynx to the trachea into the main bronchi and it will bifurcate into the left and right main stem bronchus. After that it will pass through the smaller branches of the bronchioles. Through there it will pass to the alveoli; which is the "bunch of grapes".
B. Muscular Strength. I'm almost positive that's the answer.
