Answer:

C.

The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.

Explanation:

Since the aim of the study is to know the effect of folic acid on the process of DNA synthesis, the experimental system should be given a different amount of folic acid. Respective change in DNA synthesis would represent the effect of the amount of folic acid on the process. Therefore, the amount of folic acid is the independent variable which would affect the dependent variable, that is, the DNA synthesized.

NeTakaya

Answer:

(E) left atrium.

Explanation:

Pulmonary veins are veins that carry oxygenated blood from the lungs to the heart (left atrium). These veins are part of the pulmonary circuit:

Venae cavae are a vessels (vena cava interior and superior) that carry deoxygenated blood from the body to the right atrium. From the right atrium through the tricuspid valve the blood goes into the right ventricle. Then, from the right ventricle through the pulmonary valve the blood goes into the main pulmonary artery which carries deoxygenated blood to the lungs (to recieve oxygen). Oxygenated blood from the lungs travels to the heart: two pulmonary veins from each lung to the left atrium.
