Answer:
B) The "lub-dub" sound originates from blood turbulence through the heart.
Explanation:
The systole and diastole in the heart produce the lub and dub sound in the heart.
The systole represents the contraction of both left and right ventricles and pumps the blood to the body and the right ventricle to the lungs. This involves the opening and closing of the valves. The closing of the atrioventricular valves produces lub sound.
At the end of the systole or ventricular contraction or when the blood has been pumped to the aorta and the pulmonary valves then the semilunar valves present in the aorta and pulmonary closes. This produces a sound dub.
Therefore,lub dub is associated with the physical contraction of the heart but not the turbulence of the blood.
Thus, the selected option is the correct answer.
In incomplete dominance, heterozygous<span> phenotype is intermediate between two homozygous phenotypes. In this case, the symbols for alleles are capital letters. For example, allele A is responsible for red color of a flower, allele B is responsible for white color of the flower. Red flower plants have AA genotype, and white flower plants have BB genotype. By crossing plants with red flowers and white flowers, due to incomplete variance, the offspring will be heterozygozs plants (AB) with neither red nor white flowers, but pink flowers. Pink flowers have intermediate color between red and white flowers.</span>
Answer: The Doctor is treating her for Carpal tunnel syndrome (CTS). It can be treated with Non Steroidal Anti-inflammatory Drugs (NSAIDS) and pain relief drugs

Carpal Tunnel Syndrome (CTS) is a disorder which is caused by the compression of the median nerve located in the wrist. As Kathy continually types on the keyboard the median nerve is being compressed for a longer time causing inflammation.
Carpal Tunnel is an area in the wrist where bones and ligaments create a small passage way for the median nerve. Carpal Tunnel Syndrome is therefore caused by the compression of the median nerve in the wrist. The symptoms include feelings of numbness, tingling, burning sensation over the surface of the thumb, forefinger, middle finger, half of the ring finger some feel pains from the wrist up to the arm.
They can be treated with Non Steroidal Anti-inflammatory Drugs (NSAIDS) and ibuprofen to treat the inflammation and for pain relief.
